Grow Room too Cold? Here Are 7 Hacks & 6 Products That Actually Work!
Home»Environment» Is it too cold in the grow room? Here Are 7 Product Hacks6 Products That Really Do Work! 13888Views0 Plants are killed by cold temperatures. Indoor plants, in particular, require special care because they are not protected by ‘Mother Nature.’ And you, as a savvy grower, deserve to be recognized for your efforts. So, what are the dangers of having a grow room that is excessively cold? To be more specific, such a drastic drop in temperature may cause harm to the leaves and roots of plants, resulting in less germination and, ultimately, less production.
You could have have purchased heaters or made a few modifications to your growing system in order to cope with the problem.
This is especially true if your tent is situated in a poorly separated area.
Take a deep breath and congratulate yourself on the back since you have paid attention to this content.
How Cold is ‘Too Cold’ for A Grow Space?
The temperature of the grow tent never stays the same throughout the day. During the day and at night, it is more probable that the temperature may increase and decrease in cycles. It is expected that this temperature limit will be different for warm-season crops than it is for cool-season crops, depending on the crop. Ideally, daytime temperatures should be in the mid-70s and nighttime temperatures should not be lower than 60 degrees for Warm Season Crops. For Cool Seasoned Crops, the daily and overnight temperature limitations should be set at 60 and 50 degrees Fahrenheit, respectively.
Because opening the tent to check the temperature might cause the plants to be chilled, utilize a system that remotely monitors the temperature for you.
It computes the maximum inlet/outlet temperature for the last 24 hours and turns that information off.

Grow Room Too Cold Symptoms
Placing a thermometer in the grow room and recognizing the most comfortable temperature range is the most effective technique to identify a “too cold” growing environment. Apart from that, keep an eye out for the following signs and symptoms:
- Growth that is small and weak
- Damp regions and unwelcome mildew
- Root systems that have been let to cool down (Hydroponics)
- Plants with an unpleasant taste, smell, color, or density
Problems that A Cold Grow Room Suffers From
In addition to the numerous problems that a “too chilly” grow room might encounter, here are three of the most significant ones to consider:
The majority of growing plants germinate effectively at temperatures ranging from 65 to 75 degrees Fahrenheit. Some warm-season flowers and crops, such as tomatoes, like temperatures in the 80s and higher. However, if the temperature inside the grow tent is lower than 60 degrees, it is unlikely that the plants will even begin the germination process. Eventually, this results in a low and unsatisfactory yield.
Higher Oxygen Concentration
When the temperature is between 65 and 75 degrees Fahrenheit, most growing plants germinate effectively. When it gets to be over 80 degrees, several warm-season flowers and vegetables flourish. With a grow tent that is less than 60 degrees, you can’t even expect the plants to start their germination processes. The result is a low and unsatisfactory harvest in the end.
A Damp And Unhealthy Grow System
Because of the low temperature, a few cold or hot patches may appear in various locations across the whole room. This eventually results in a moist atmosphere and the growth of undesirable mould. Both of these concerns have the potential to cause significant harm to your plants, as well as over-purpling leaves.
7 Actionable Hacks to Deal Wih A Cold Grow Space
Let us now turn our attention to the more positive aspects of the article. From here on out, we’ll be talking about several hacks and ways for raising the temperature to a more comfortable level than usual. Instead of throwing money at the problem, examine the following few tricks that may help you get out of it:—
Insulate As Much As Possible
The temperature within your grow chamber is already quite low. Therefore, you never want the heat to escape before it has a chance to reach the plants and nutrients. And the most effective approach to achieve this goal is to insulate the room as much as is reasonably practicable. Now, insulating a grow room does not just imply ducting the airflows out of the space. Here is a comprehensive list of the insulating tasks you must complete:
- You’re already battling with a chilly temperature inside your grow chamber. Therefore, you never want the heat to escape before it has a chance to reach the plants or nutrients. And the most effective approach to achieve this goal is to insulate the room as much as is reasonably practicable. In order to properly insulate a grow room, it is not just necessary to divert airflows. A comprehensive list of the insulating projects you must perform is provided below-.
Keep Lights on Instead of Plugging In A Heater
Say, for example, that your plants are in the process of vegetative development or are not sensitive to photoperiods. In either event, you are not need to have a heater plugged in in order to cope with the cold snap. Instead, it is preferable to utilize as many grow lights as possible to maximize yield. You may now raise an eyebrow at the idea of operating grow lights 24 hours a day, seven days a week. However, the reality is that even 5-6 hours of heater operation will consume less power than that.
Improve Air Circulation
You’re going to do something that will increase the amount of heat generated within the grow room. How would you feel if the heat doesn’t go to the plants and instead ends up generating hotspots? Make certain that the heat is circulated throughout the whole room. Some heaters, such as fans, come up with their own technique of circulating the air. However, for many of them, you will need to disseminate them inside your organization. The most effective method is to utilize a standby fan.
Take The Air Intake from A Warmer Space
Another factor contributing to the low temperature is a lack of warm intake air.
And this is due to the fact that the intake air is imported from a location that is not as warm as the grow room itself. Attempting to resolve the problem may result in an increase in the minimum temperature of your grow environment.
Putting the Exhaust Fan into Timer
It is necessary to have a pair of intake and extraction fans running in order to maintain optimum ventilation. Because you have internal heating sources such as grow lights and heaters, this is usually not a problem for you. What happens, though, if the lights are turned off? Should the extractor fan be turned off in order to keep the heat trapped inside? No. However, you must make every effort to keep the fan speed as low as possible. Connecting the extractor fan to a Day/Night Fan Speed Controlleris the most efficient solution in this situation.

Enhance The Nutrient’s Heater by 20%
Not only may you be suffering from a cold grow area, but you could also be suffering from chilled nutritional solutions. When applied to your plant’s leaves, a chilly nutrition solution might cause significant harm. As a remedy, you may try raising the fertilizer strength by 20 percent (or so), which would allow the plants to absorb the essential nutrients while using as little water as possible to do so. Eventually, the negative impacts of low temperatures on the health of the plant will be greatly reduced.
As a result, commercial producers may have to make adjustments to compensate for the increased nutrient intensity.
Turn Composts Into Heat Sources
It is possible that you are suffering from not just a cold grow space, but perhaps chilled nutrition solutions as well. When applied to your plant, the effects of a cold nutrition solution may be devastating. Increasing the fertilizer strength by 20 percent (or so) may be an option as a remedy, allowing the plants to absorb the required nutrients while using the least amount of water. Overall, the negative impacts of low temperatures on plant health are expected to be greatly reduced. Eventually, Keep in mind that plants transpire less when they are kept in a cool environment!
6 Best Heat Sources for Your Grow Space
If you don’t already have a solution to your problem, this is the most familiar and perhaps the most effective one. In a general sense, we may categorize all electric heaters according to the size of the grow room they are intended for: 1) Electric heaters for Grow Rooms. 2) Grow Tent heaters powered by electricity. The differences are as follows:
- SizeHeating Capacity Heaters for grow rooms are often greater in size and weight, but heaters for tents are smaller and lighter in weight. The wattage (measured in Watts) of room heaters ranges between 1500 and 2000 watts, whereas tent heaters range between 750 and 1500 watts. Runtime It is possible that you may need to operate the heater during specified hours of the day, mostly dependent on the light cycle. Smaller heaters will perform admirably for an 18/6 or 16/8 light cycle, thanks to the 8 hours of continuous operation. The bigger ones are more suited for grow rooms, where you may need to keep it running for up to 24 hours at a time.
- Ceramic vs. Oil Filled: Which is better? This is yet another significant distinction that may have an impact on your purchasing decision. A straightforward explanation of the difference between an oil-filled and a ceramic heater is that it is the medium used to generate heat that is important. An oil-filled one, on the other hand, has fins that are filled with heated oils, resulting in the generation of radiant heat. Furthermore, in the case of ceramic heaters, ceramic is the heating medium that generates radiant convention heat
In the event that you do not already have one, it is the first and most important tip for dealing with your heating problem. When choosing one for your grow area, bear in mind the pricing, the energy cost, and the location of the unit.

Grow Tent Tube Heaters
A tubular heater is the most effective and simplest heating solution available on the market today, out of all the choices available. It is energy efficient, consuming only a few watts of electricity (90-200W), and is an excellent choice for expanding environments with limited floor space. The best tube heaters available on the market are equipped with a variety of advantageous features such as a safety cutout, overheating prevention, and adjustable legs, among others. It is possible that more than one of these heaters may be required for a bigger room.

Heating/Cooling Mini Splits
If you live in a continental climatic zone, you are well aware that the winters are too cold and the summers are too hot. You’re currently dealing with a temperature drop, and you’ll be dealing with an overheating problem in the summer. At some point, you’ll have to spend money on both cooling and heating solutions. Why don’t we integrate the two of them into a single package? I’m referring to the Heating/Cooling Mini Split that you’re probably already familiar with. It has one indoor unit and one outdoor unit, and it has a broad range of BTUs to choose from.
You can be concerned about the pricing and the expense of electricity.
However, if you make an informed purchase, your model may result in a 30 to 50% reduction in energy use.
When faced with a problem like as a chilly grow room, the majority of us growers concentrate on heating the air within it. However, one of the first things to attempt is heating the soil/seeding instead of watering it. These mats have a specific mission: to preserve the soil temperature between optimal limits, which are typically 75-85 degrees Fahrenheit. In practice, heating the air is a much more expensive method of obtaining the desired result. Some people exclusively use these mats as germination mats all of the time.
Make no mistake, though, because these mats are excellent for heating soil long after the germination stage. Our recommendations are as follows: Soyon Aquarium Heater, 300 watts A Less Expensive Alternative: U-picks Aquarium Heater with Thermometer (30W)
Aquarium Heater: To Warm Up The Nutrients
Cold roots are one of the most serious risks to any grower, but they are extremely dangerous for those who grow in a system with no medium. NFT(), DWX(), Aerophonics, and other media-less systems are examples of what I mean by media-less systems. Reason? These types of plants, on the other hand, do not benefit from the insulation that growth media such as soil may give. The answer is straightforward: simply heat the nutrition solution from the outside. Aquarium heaters are a fantastic tool for accomplishing this.
Observations and Recommendations
We recently discussed the process of converting soil composts into heat-storing compost heaps, which has proven to be quite effective. This time, though, we’re talking about putting the identical concept into action with a barrel of water. To construct this heatsink, you may use a 55-gallon barrel or any other readily available water storage container. Place the container in a location where it will be exposed to direct sunshine. Later on, place it inside the grow chamber and let the water to transfer heat energy into the environment.
To achieve the best results, utilize a dark tank with high heat absorption capacity.
Frequently Asked Questions(FAQ)
Is there an optimal time of day to turn on the heater? Answer: It is dependent on the temperature outside of the growth tent as well as the amount of heat required by the plants. Typically, it should be in the late afternoon or early evening, when the weather is beginning to calm down. Heating, on the other hand, is a necessary evil during the winter months. The question is, how do you keep a grow room warm while the lights are turned off? Using something like an automated fan speed controller that operates regardless of whether the lights in your grow room are on or off is a good solution.
Question: What is the most cost-effective method of heating a grow room?
The provision of intake air from a warmer environment is perhaps the most cost-effective solution available.

How Do You Heat a Grow Tent [It’s Easier Than You Think]
When you make a purchase after clicking on one of the affiliate links on this site, Growing Marijuana World may get a commission. For a complete list of affiliates, please see the sidebar. One of the challenges of growing a healthy plant inside (in a grow tent) is ensuring that the environment is warm enough for your plant(s) to thrive. There are several approaches that may be used to accomplish this; sometimes you simply need to be a little more imaginative in your approach. If you maintain a regular growth temperature for your marijuana plants, they will respond more positively to your care.
Additionally, by regulating the temperature outside of the grow tent, a grow tent may be heated.
Unlike what you may expect, there are possibly more options for heating a grow tent than you might believe.
The size of the marijuana grow tent will help you determine which type of heater is most appropriate for it.
Some methods may be more appropriate for a smaller room, whilst others may be more appropriate for a much bigger size. ** Do you want to get right to the point? Visit Amazon to see thisOil filled Radiator Heater**, which I strongly suggest.
How to Increase Temperature in a Grow Tent
If you make a purchase after clicking on one of the affiliate links on this site, Growing Marijuana World may get a commission. Full affiliate disclosure may be found on the sidebar. In order for a healthy plant to thrive when grown inside (in a grow tent), one of the most difficult aspects of the process is getting the room warm enough. While there are several methods for accomplishing this, sometimes it is necessary to be a little more imaginative in your approach to the situation. Maintaining a steady growth temperature for your marijuana plants can help them react better.
- Additionally, by controlling the temperature outside of the grow tent, it is possible to heat the tent.
- A grow tent may be heated in a number of different ways, which is surprising given the limitations of the space available.
- When determining the type of heater to use for your marijuana grow tent, consider the size of the tent.
- ** Interested in getting straight to the point?
Heating a smaller grow tent
- In a 5 gallon bucket, an aquarium heater is being used. It’s a good concept for a room with a floor area that’s less than 4′ x 4′, in my opinion. Fill a 5-gallon bucket halfway with water, and then submerge an aquarium heater in the water. Connect the heater to the wall outlet. Because of the way the heater works, it will help to keep the water warm while also helping to warm up the growing space by default. This strategy will also increase the humidity in the environment, which is beneficial to your plant. The presence of a grow tent near an outside heat source is sometimes all that is required to maintain a comfortable temperature. Heat may be distributed through the tent by positioning it near an operating furnace or ductwork. If you have an air conditioning unit operating in the summer, this may not function as effectively as it should. If you have a location with south exposure and the sun shining through a window, this could provide you with enough heat inside the tent as the sun warms it up every day
- If you have a location with north exposure and the sun shining through a window, this could provide you with enough heat inside the tent. If you want more control over the temperature in your tiny grow tent, I recommend utilizing a small space heater. Insulating the outside of your grow tent with fiberglass insulation or Styrofoam insulation can assist to maintain temperatures consistent and will also aid in the warm up of your grow tent. There are practically hundreds of them available for purchase on the market. Make certain you select one that is designed exclusively for compact places. Honeywell manufactures a great space heater that radiates heat in all directions. It is also equipped with a thermostat, allowing you to guarantee that the temperature of your grow tent remains constant. Preparing and Heating a Larger Grow Tent
The process of heating a larger grow tent will be similar to that of heating a smaller grow tent. The one thing I wouldn’t attempt in the larger tent but would in the smaller one is the aquarium heater in a bucket of water method, which I believe would work in both. This will not work with a larger tent since it is simply too vast.
- An oil-filled radiator is an even better option than utilizing an electric space heater for bigger tents that are likely to have a huge crop growing in them. If you have a large crop growing in your tent, a space heater is nearly always necessary. Why? Because a space heater is circulating hot air around the room. If they approach too close to the plants, they may cause them to dry out too rapidly or burn the leaves. When an oil-filled radiator warms up, the heat radiates out from the radiator’s surface. This implies that the space will become warmer when hot air is blown over the plants. DeLonghi’s model, which is referenced above, is a great pick. As a precaution, have an oscillating fan going in your grow tent to assist in distributing heat evenly over the plant canopy. If this is not done, one side of the room will be significantly warmer than the other.
What Temperature Should Grow Tent be?
Ideally, the temperature should be between 20 degrees Celsius (68 Fahrenheit) and 28 degrees Celsius (82 Fahrenheit) in order to optimize the development potential of your plants (82 Fahrenheit). Temperature fluctuations are possible without causing significant (or any) damage to your crop. Temperatures that are too cold or too hot for a lengthy period of time can stunt or destroy your marijuana plant. Keep the temperature inside the tent no lower than 20 degrees Celsius (68 degrees Fahrenheit) and no more than 31 degrees Celsius (88 degrees Fahrenheit) (87.8 Fahrenheit).
Despite the fact that space heaters and oil radiant heaters are equipped with thermostats, it is a very good idea to have a second thermostat in the room, which should be situated on the opposite side of the room.
As a result, placing a thermostat close to the heater may result in inaccurate readings. The Thermopro Digital Hygrometer is a dependable thermometer that also includes a humidity indicator as a bonus feature. It is extremely reasonably priced and simple to use.
Best Temperature for Flowering Stage
Ideally, the temperature should be between 20 degrees Celsius (68 Fahrenheit) and 28 degrees Celsius (82 Fahrenheit) in order to optimize the development potential of your plant (82 Fahrenheit). Temperature fluctuations are unavoidable, and your crop will not suffer much (if any) from them. Long periods of extreme cold or extreme heat can cause your marijuana to deteriorate or be destroyed. Don’t allow it get any colder than 20 degrees Celsius (68 degrees Fahrenheit) inside the tent, and no hotter than 31 degrees Celsius (88 degrees Fahrenheit) (87.8 Fahrenheit).
It is a very good idea to have a separate thermostat in the room, preferably on the other side of the room, even if space heaters and oil radiant heaters have thermostats built in.
As a result, placing a thermostat adjacent to the heater may result in inaccurate readings of the temperature.
It is quite reasonably priced and simple to use, as well as convenient.
How to Keep Temperature Down in Grow Tent
Please continue reading if you are experiencing problems with the grow room temperature being excessively high for lengthy periods of time. In rare cases, if there is no means to exhaust the air out of the grow room/tent, confined spaces can get dangerously hot. If you are using a professionally built grow tent that you acquired from a provider who sells them for you to grow plants in, there should be a particular area designated for ducting. If you are using a grow tent that you constructed yourself, there should be a specific location designated for ducting.
After it has been properly fitted, this ducting will fit exactly into the ventilation hole.
Tip of the Day
Do not keep your space heater or any other item (such as a fan) in the tent that has an LED light on all of the time if it is being used. If the plants do not receive total darkness when the lights are turned off, they may develop the ability to transform into hermaphrodites. If this occurs, your buds will not be as potent as they were before the seeds began to develop. When you smoke it, the buds will also be a little harsh. An easy solution is to cover all of the LED power lights with some electrical tape until the problem is resolved.
Just make sure you aren’t stealing a peek when the plants are in the midst of their slumber.
Seedling Mats are another Option to Heat Marijuana
Seedling mats are designed to be used to get seeds started in the developing process. Heating the roots and soil of a pot plant that is in the process of growing is absolutely not a terrible idea. The only thing you have to do is place a seedling pad below a plant container and put the light on. They never exceed the temperature that has been set. Temperatures often range between -12 degrees Celsius (10 degrees Fahrenheit) and -6 degrees Celsius (20 Fahrenheit) It is also fairly priced, which makes this Vivosun 20″ x 20″ mat a great value for money.
An very huge pot might comfortably be placed upon this mat’s surface. There are also many different sizes to pick from, allowing you to ensure that you have a seedling heat pad under each and every one of your marijuana plants.
As a result of reading this article, you should have a clear understanding of how to heat your grow tent effectively. I’ve given you with a number of fantastic alternatives. The space heater is my favorite out of all of these options. Just keep in mind that you may want to open the windows to get some fresh air into the room. In addition to dissipating heat, this is an excellent method for getting rid of the weed’s unpleasant scent. You may also connect a charcoal filtering device to the system to remove the smell.

How Can I Keep My Grow Tent Warm in Winter
Winter brings with it a hazy, musty dawn as well as colder, windier temperatures. Winter is a season marked by snow, frost, and freezing temperatures in various parts of the world. We have a plethora of alternatives to keep us warm and comfortable throughout the winter months. But have you given any consideration to the plants in your grow tent? Is it possible for you to cover them in blankets and coats to keep them warm? Alternatively, would you give them hot coffee to help them feel more comfortable?
Growing tents are kept warm by a variety of methods, the most popular of which being bubble wrap and humidifiers.
Whenever the temperature falls below 15 degrees, you’ll find that the growth of your plant has come to a complete halt.
How Can I Keep My Grow Tent Warm In Winter
Electric heaters or fan heaters can be used to keep your grow tent warm if the weather is cold. This method distributes heat throughout the whole tent. This is generally seen as the safest choice since it heats the space without releasing moisture into the air, whereas the other options do. When used in conjunction with a grow tent, this heating system will allow your plants to thrive even in the coldest conditions. If your grow tent is less than 4′ by 4′ and you’re looking for a more economical solution, you may also experiment with aquarium heaters.
When you need the heater to function, you must first connect it to a power source.
It’s important to remember to open the tent’s windows when the weather is nice. In addition, there are many different types of grow tent warmers available on the market today. You can make your selection based on your requirements.
Let The Sun Do The Job
If your grow tent receives direct sunlight from the south, consider yourself fortunate. When the sun shines through the window, it really heats up the room within the window. If you follow these instructions, you will have no trouble keeping your grow tent warm. Insulate the tent so that the heat it is receiving from the sun does not escape through the tent. When the weather is gloomy, though, don’t rely on the sun to heat your home. These days, you have to rely on alternative techniques.
Insulate The Tent
In the winter, the temperature is already far too low. Now, if you don’t adequately insulate the tent kit, the heat will escape from the tent and you won’t be able to heat it effectively no matter how hard you try. Insulating a place does not merely mean preventing air from escaping from the area being insulated. Many additional things may be done, such as covering the plant pots with aluminum foil papers and laying a plastic sheet or rug on the floor to keep the floor from being too cold. Maintaining a physical barrier between the floor and the plant is another option.
As a result, your plants will not be affected by the cool floor temperature.
If your tent is sufficiently warm, you won’t have to be concerned about the growth of your plant.
Change Lighting Period
Assume your plants are in the vegetative state at this point. It is preferable to keep the grow lights on at this time rather than turning on the electric heaters. Making use of as many grow lights as feasible for a whole 24 hours rather than an electric warmer for 5-6 hours is a smart option in most cases. You won’t have to be concerned about your electricity cost because grow lights consume less energy than electric heaters. High-intensity discharge (HID), compact fluorescent, and LED lights are among the finest grow lights for winter.
As a result, if you reside in a colder climate, you should consider purchasing HID grow lights for your tent during the winter months.
Add More Lights To The Tent
Suppose your plants are in their vegetative state at this point. Grow lights should be kept on at this time, rather than turning on electric heaters. It is actually preferable to use as many grow lights as possible for 24 hours rather than an electric warmer for 5-6 hours. Because grow lights consume less energy than electric heaters, you won’t have to be concerned about your electricity bill! Winter grow lights such as HID, compact fluorescent, and LED lights are among the most effective options.
Consider investing in high-intensity discharge (HID) grow lights for your tent during the winter if you reside in a colder region of the country.
Supplement Your Plants with Nutrients
When it comes to feeding your plants with nutrients, you must exercise extreme caution. Make certain that the water temperature remains between 18 and 21 degrees Celsius when you are producing nutritional solutions. During the process of supplementing, it is important that the water temperature does not go too low. If you do not do so, your plant’s roots may experience stress, which may cause the absorption rate to slow down. Because of this, the development of the plants in your tent is stunted.
As it lowers the oxygen level in the atmosphere, the growth will slow down once more.
Alternatively, you might try combining the nutrient solution with cold water and then placing a water warmer in the water tank to avoid such issues from occurring.
Also, use caution when storing the solution in a storage facility.
As a result, your plants will not be able to benefit from this element. To avoid such a catastrophe, keep the solution in a cold and dark area where sunlight cannot reach it and the temperature is between 10 and 19 degrees Celsius at all times.
Using A Thermostat
A thermostat is a device that may be used to regulate the temperature of electric heaters. As a result, when your grow tent becomes excessively heated, the electric heater will be turned off, and when the room temperature becomes excessively low, the heater will be turned back on. You’ll be able to save some electricity this way.
Consider Using Horticultural Fleece
To control the temperature of an electric heater, a thermostat can be used. It will switch off the electric heater when the temperature in your grow tent becomes excessively high, and turn it back on again when the temperature in your room becomes too low. You’ll be able to save some electricity this way.
Take Care Of The Temperature
A thermostat is a device that may be used with electric heaters to regulate the temperature. As a result, when your grow tent becomes excessively warm, the electric heater will be turned off, and when the room temperature becomes excessively low, the heater will be turned on once again. You will be able to save some electricity in this manner.
Use An Oscillating Fan
A thermostat is a device that may be used in conjunction with electric heaters. Consequently, when your grow tent becomes excessively heated, the electric heater will be turned off, and when the room temperature becomes excessively low, it will turn the heater back on. You’ll be able to conserve some energy this way.
Ventilation is just as important as heating up the tent in terms of comfort. Heat causes moisture to be released into the air, which necessitates the requirement for ventilation. Alternatively, molds and fungi might destroy your plants, resulting in your efforts being completely ineffective. You can open windows and doors, especially during the daytime when the sun is shining, to let moisture to escape from the grow tent. This will undoubtedly bring happiness to your plants’ lives.
Place The Heater Carefully
If the electric heater is placed towards one end, it will allow for a more even distribution of heat over the whole tent, which is ideal. It is not recommended that the heater flow directly on any close plants.
We spoke about a few different ways to keep your grow tent warm over the winter. The weather permitting, you can select any of them or more than one at the same time depending on your preference. It is necessary to choose between two or more possibilities when the temperature gets cooler. When the weather is nice and sunny, on the other hand, you may leave it to the sun. Make certain that you have a good ventilation system in place to keep your plants disease-free.
How to deal with your grow tent getting too cold
The ways for keeping your grow tent warm throughout the cold months were explained in detail. Depending on the weather conditions, you can pick any of them or more than one at the same time. You must choose between two or more possibilities when the weather gets cooler. When the weather is sunny, on the other hand, you may leave it to the sun. Keep your plants disease-free by ensuring that they have a sufficient ventilation system.
- Ventilation from a lung room (a crawlspace, attic, or other area in your home that does not become as cold as the outside environment) is recommended. Fan speed controllers may be used to adjust the speed of your intake and exhaust fans. It’s possible that some fine tuning will be required here. Remember that if you’re using air conditioning to cool your lights, installing a fan speed controller to the duct fan(s) that circulate the air that cools your lights is also an option. We do not normally advocate using a thermostat to manage the intake and exhaust fans (although they are excellent for cooling your tent when temps become too chilly), since we want enough air exchange to maintain appropriate CO2 and humidity levels. If your grow tent is becoming excessively cool as a consequence of drawing in cold air, installing a thermostat will merely guarantee that your intake and exhaust fans are seldom used
- However, this is not the case in most cases. Remove the glass from your hoods. Even if you use passively cooled HID lights in your grow tent, merely passively cooling your lights will result in a significant increase in the temperature of your grow tent. Not to mention that de-glazing your hoods will result in an additional 10-15 percent of accessible light for your plants. Make a diffuser for the air. It is possible that the plants closest to the cold air coming in from your intake will suffer if the temperature differential between the cold air and the warm air coming in from your intake is significant. The creation of an air diffuser is a wonderful choice for preventing your plants from being shocked. The use of flexible ducting is a simple and effective do-it-yourself solution. Install a piece of ducting from your intake fan that is long enough to completely encircle your growing tent. After that, secure the ducting’s end with a plug. Then, every several inches down the length of the ducting, make tiny slots in it. Congratulations, you have successfully constructed your own air diffuser. Increase the amount of light. Have you considered adding extra light to your grow tent instead of putting in a heater (which is typically not a good suggestion because it might be a safety hazard depending on the size of your tent)? If you have not optimized your grow area by ensuring uniform light distribution throughout, then increasing the amount of light available is an alternative. Why would you spend more to run an expensive space heater when you can just install a HID or T5 fixture, which produces both light and heat, and kill two birds with one stone?

Quick Answer: How To Heat My Grow Tent
When it comes to heating a grow tent, you have two options: you may either put the heater within the tent or outside the tent, depending on the size of the tent. The placement of the heater outdoors is perfect for grow tents that are smaller than 6×6 feet. Using a fan to circulate the air in the area where the tent was placed can provide even more heat after the space has been warmed up.
How do I keep my grow tent warm?
As an alternative to setting up your grow tent on a chilly floor, you may use a carpet or rug to act as an additional layer of insulation. With addition to wrapping the entire tent in building insulation, if it helps to keep your house warm, it should work to keep your plants warm as well. 15th of November, 2018
How do you heat a grow tent in the winter?
As much as possible, insulate your home. If you’re growing in pots, cover them with Aluminum Foil Sheets to protect them from the elements. If the pots are in direct contact with the chilly floor, use a Polystyrene Plastic Sheet between them to protect them from the cold. Wrap the whole grow tent from the outside, ensuring that there is no opportunity for the heat to escape.

Temperatures in the 70-85 degree Fahrenheit (20-30 degree Celsius) range are often preferred by cannabis plants throughout the daytime while lights are on. When the lights are turned off (or when it is night), cannabis plants thrive in somewhat colder temperatures.
How hot should my grow tent be?
Temperatures in the 70-85 degree Fahrenheit (20-30 degree Celsius) range are often preferred by cannabis plants throughout the daytime while the lights are on, in general. Marijuana plants thrive at colder temperatures when the lights are turned off (or at night).
Is 85 too hot for a grow room?
It is recommended that plants grow in grow rooms between the temperatures of 68 degrees and 82 degrees Fahrenheit, depending on their stage of development. However, if you keep your plants at 85 degrees Fahrenheit for an extended period of time, they will begin to experience a variety of problems.
Can I leave my grow tent open?
Yes, theoretically, you are allowed to keep it open. It is my goal to be able to control as many factors as possible, and growing under a tent allows me to do this. You’re exposing your plants to everyone and everything in the room as a result of this.
How can I cool my grow room without AC?
How To Keep A Grow Tent Cool Switch to LED grow lights to save money. Ballasts and drivers should be placed outside the grow tent. Air should be circulated in and out of the tent. In the grow tent, keep an oscillating fan running. Incorporate a Swamp Cooler into your tent. Install a portable air conditioner in the tent. Turn on the lights at night. Relocate the grow to the basement or cellars.
Can you have too much airflow in grow tent?
Having an excessive amount of CFM flow in your tent is not necessarily an issue, unless you don’t have enough passive intake ports and the tent walls are bending in, in which case the fan will be put under undue stress. In such situation, you may also use active input fans to aid in the system’s overall balance.
What happens if grow room is too hot?
Too much CFM flow in your tent is not an issue unless you don’t have enough passive intake vents and the tent walls are bending in, in which case it will put excessive strain on the fan and cause it to fail prematurely. It is possible to add active input fans to the system in that situation, which will aid in system balance.
Is 32 degrees too hot for Grow Tent?
Moderator. Anything beyond 30 degrees Celsius/86 degrees Fahrenheit should be avoided at all costs. Because of the high temperatures, the plants become stretched and their buds become smaller and more airy. There are some strains that will fare better in hot temperatures than others.
How long should a fan be on in a grow room?
It is recommended that your grow room’s extractor fan system replenish the air in your grow room once per minute, or at the very least every three to five minutes.
How do you insulate a grow room?
It is likely that closed cell spray foam will be the ideal choice for your grow room since it will assist you in controlling both the temperature and humidity levels required to produce the greatest product possible.
Spray foam will transform the area into the airtight, climate-controlled environment that your plants require in order to develop properly.
How hot is too hot in grow tent?
Almost each grow room plant can endure temperatures between 90 and 100 degrees Fahrenheit, and even greater temperatures. If you live in a hot climate and are unable to find a rapid way to manage the temperature, but still want to maximize your yield, you should chill the nutrients to a temperature between 55 and 65 degrees Fahrenheit.
How To Keep Your Grow Room Warm During Winter
This is especially crucial when growing in a system since, unlike growing in soil or coco coir substrates, which provide a limited degree of insulation to the root zone, growing in water does not provide any. Plants need warm air around them; the ideal temperature range for your growing environment is around 25-28°C during the period when the lights are turned on. When the lights are turned off, it is recommended to keep the temperature between 18 and 21 degrees Celsius. Plants may instinctively feel when the winter months are approaching by observing changes in temperature.
As soon as the temperatures begin to decrease, we begin to see a slowdown of plant development.
If your plants’ development is hampered in this way, it may take them up to two weeks to recover and resume regular flower and fruit output.
Nobody wants to miss out on two weeks of flowering time, especially since it has a direct influence on the size and quality of the plants.
An well insulated grow chamber is essential for keeping the temperature of the plants constant. Instead of putting your grow tent on a chilly floor, cover it with a carpet or rug to act as an additional layer of insulation. With addition to wrapping the entire tent in building insulation, if it helps to keep your house warm, it should work to keep your plants warm as well.
Because of the heat they generate, high-intensity discharge (HID) lights indoors can be problematic during the summer. Take advantage of this during the winter months by keeping your ‘lights on’ phase running at night when ambient temps are colder and your ‘lights off’ period running during the day. The heat generated will contribute to reducing the effects of the chilly evenings. During the winter months, while plants are still in vegetative development, gardeners might consider expanding the ‘lights on’ time from 18 to 24 hours.
- Similarly, high-intensity discharge (HID) illumination can create issues throughout the summer.
- This is owing to the fact that LEDs do not generate a lot of heat.
- When utilizing a heater, it is important to monitor your humidity levels since the heater has the potential to dry up the air, resulting in a much lower relative humidity when the heater is running.
- When you reach this stage, you will have complete control over your surroundings, and should any difficulties develop, you will be equipped with the necessary tools to resolve them.
The extra light will work as a heat generator, keeping the temperature elevated even under extreme weather conditions, and your plants will be grateful for the increased lumen output!
Heating your growing area with auxiliary heating is almost always necessary since the heat generated by lights is insufficient to keep your growing space at the optimal temperature! Heaters are tiny enough to be positioned at any level in your growing area and provide a continuous distribution of heat in the surrounding air, allowing you to maintain a consistent temperature in your growing space at a low operating cost. If you want to be able to regulate the temperature of your grow tent or room, Oil Filled Radiators are an excellent choice.
In the third place, there is a fan heater, albeit these should be used with caution since the dry, hot air can drop humidity and cause harm to plants, as well as inhibit development when it is blown directly at them.
It’s best not to have it in the grow room, but if you have no choice, make sure it’s not pointing directly at the plants or consider switching to an Oil Filled Radiator.
Give your plants some warmth
During the winter months, your plants may require additional assistance in order to protect themselves from temperature fluctuations and truly develop to their fullest potential. VitalinkHeat is an excellent answer to this problem, as a tiny quantity may be used for an extremely long period of time. Using heat to assist your plants establish a tolerance to the cold before the winter actually sets in can be beneficial. Heat should be used carefully since overdoing it may be detrimental to your plants.
Directions may be found on the label of the bottle as well as on this website.
Keeping the temperature between 18 and 21 degrees Celsius is critical when mixing nutrient solutions, especially in large quantities and keeping them in a water tank over a period of several days. It is possible for the roots of plants to go into shock if the temperature goes too low, causing them to slow down their absorption and hinder their growth. Alternatively, if the temperature is too high, the oxygen levels will drop, plant development will halt again, and the plants will become more vulnerable to diseases such as Pythium, commonly known as Root Rot.
Because they are completely submersible, they are able to remain submerged in the water tank and maintain the temperature of the solution at all times.
If your storage environment is excessively cold, the dissolved salts that make up your nutrients may crystallize and solidify, rendering them useless.
To avoid this, keep nutrients in a cool, dark spot that is out of direct sunlight and where temperatures range between 10 and 19 degrees Celsius. As a general guideline, you should never keep your nutrients at temperatures lower than 5°C.
Watch Your Intake
By pulling in outside air into your growing environment, you are introducing the cold into your growing space and making it more difficult for your plants to maintain their heat. Change the location of your intake fan so that it is pulling air from inside the building, and make sure it is coming from a different region than the expanding space. There is also the added benefit that the air taken from within will not only be warmer, but it will also be richer in CO2 than the air drawn from outside.
It is beneficial to lower the fan speed down by a few percent during vegetative development and early bloom because it allows the warmer air to remain in the room for longer while still providing sufficient fresh air for the plants’ growth.
Secondary heating, as described above, should still be explored.
Plants grow at temperatures between 25 and 28 degrees Celsius while the lights are on, and in temperatures between 18 and 21 degrees Celsius when the lights are turned off. It is crucial to check your temperatures on a frequent basis to ensure that these conditions are continuously met. Using a Digital Thermometer is the most accurate approach to determine whether or not something needs to be addressed in order to get the optimal temperature.
How to Minimize Heat in a Grow Tent
In order to keep consistent temperatures in a grow tent, there is a science behind it. If you’re having trouble with overheating or shifting temps, you’re not the only grower who’s had to deal with this problem before. You surely won’t be the last one to do so. Temperatures between 70 and 80 degrees Fahrenheit are generally considered to be the ideal range for your plants. This is the range in which your plants can absorb the optimal quantity of nutrients—not too much, nor too little—without being stressed.
- To make matters even more complicated, merely reducing the amount of heat generated in a grow tent is not enough.
- Temperature fluctuations stress your plants, and they will suffer as a result.
- Achieving either of these goals is difficult, especially for first-time gardeners.
- The unfortunate news is that this is the case.
Choose LED Grow Lights
The climate within your grow tent is greatly influenced by the type of grow light you choose to use. The majority of growers use either high-intensity discharge (HID) bulbs or LED lights. HID bulbs are available in two varieties: HPS (high-pressure sodium) and MH (metal halide). High-intensity discharge (HID) growers often utilize MH for the vegetative phase and HPS for flowering. This has been the conventional method of growing tent lights for many years. However, it is no longer the recommended alternative.
Even while LED technology is still in its infancy and requires a somewhat greater initial investment, the advantages it offers are numerous.
In addition, they produce substantially less heat.
It is true that you will have to deal with heat in a grow tent regardless of the sort of light you use for your plants. LED grow lights, on the other hand, make the job considerably simpler. When you utilize LEDs, you will require far less additional cooling.
Install a Quality Ventilation System
If you do not have a ventilation system, you should install one immediately. If you have one, be certain that it is connected to your property and that it has enough power to satisfy your requirements. A ventilation system regulates the temperature of a grow tent by releasing hot air and bringing in cooler air from outside the tent at the same time. A typical system consists of an exhaust fan, ducting, and a carbon filter, which is used to eliminate odors associated with plants. The exhaust fan, also known as an inline fan, is in charge of the exchange of air in the system.
The directional movement of the heated, stagnant air expelled by your exhaust fan is controlled by ducting.
Because you don’t want to introduce any more old air into the area around your tent.
On that topic, let me say.
Manage Heat in a Grow Tent by Managing HeatAroundthe Grow Tent
Think about where you’re going to put your grow tent. Keep in mind that your high-quality ventilation system will draw in all of the air from around your tent and distribute it throughout the grow room. If it’s hot in the room, you can bet it’ll be hot in the tent as well. Moving to a place that is naturally cooler, such as a basement, can be a good option for your situation. If you have central air conditioning, another option is to locate your grow tent next to air vents to maximize airflow.
Access to cooler air is provided while also making it simple to send your ducting out of the room with this choice.
Consider an Air Conditioning Unit
An air conditioning unit, whether it is placed inside or outside the tent, may make a significant difference in how well a grow tent manages heat. By putting an air conditioner inside the tent, you may exert direct control over the atmosphere in which your plants grow. However, take care not to cool things down too quickly. Even a simple oscillating fan might aid in the management of heat. A fan dissipates heat and can circulate the air to keep it from becoming stagnant. Instead of introducing another another environmental aspect to your grow tent, you may consider installing an air conditioner in the area that contains your grow tent as an alternative solution.
Remember: Electronic Equipment Generates Heat in a Grow Tent
Electricity is used to generate heat in a grow tent by drivers, hydroponics pumps, filtration systems, and any other electrical equipment that is used to produce high yields. Now, it’s evident that you’ll be unable to quit using these necessities.
These things may, however, be possible to be relocated outside of the tent while still remaining linked to the interior through the use of extension cables or longer pipes. You’d be surprised at how much heat you may save by just turning off a few electronic devices.
Run Your Lights at Night
If you set up your grow tent correctly, you should be able to provide your plants with a growing environment that is fully free of light pollution. This implies that you are not required to conform to the natural day and night cycle of the world. Your plants are completely oblivious to the change. Inside your grow tent, daytime is defined by the time you set for it. You’ll want to make sure that your plants have a regular 24-hour cycle going forward. You may, however, plan your lights-on period to occur during the nighttime hours.
Even if the light cannot reach your plants, its rays warm the space in which you store your tent, as you can see.
By using your grow lights throughout the night hours, you are exchanging one heat-producing cause for another, rather than doubling up on the problem.
Keep the Heat and Add CO₂
As a beginner, we recommend sticking to the above recommendations for keeping your heat levels low.However, if you’ve gained some experience with your home grows and are ready to move on, you might consider the following option:Instead of minimizing heat, increase your carbon dioxide levels.All things being equal, too much heat is bad for your plants.If you have any questions, please contact us.
In the same way, too much CO2 is harmful. However, by increasing both factors at the same time, you may really enhance your yields.
