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
The water will be chilled if the temperature in your grow room is lower than normal, resulting in a larger concentration of oxygen dissolved in it. While plants absorb it through their roots, it has a negative impact on their metabolism and enzymatic functions.
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:
- If you’re growing in pots, put Aluminum Foil Sheets around them to protect them from the elements. If the pots are in direct touch with the chilly floor, place a Polystyrene Plastic Sheet between them
- Otherwise, let them alone. Wrap the whole grow tent from the outside, ensuring that there is no opportunity for the heat to escape.
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:
- If you don’t have an issue yet, start with the most known, and maybe the most effective, solution. Overall, electric heaters may be divided into two categories: 1) Electric heaters for grow rooms, and 2) Electric heaters for other spaces, such as garages or workshops. Heaters for the Grow Tent (electrical) The distinctions are as follows:
- 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
Ceramic vs. Oil Filled A further significant distinction that may have an impact on your purchasing decision is the following: Simply put, the difference between an oil-filled and a ceramic heater is the material used to generate heat.
An oil-filled one, on the other hand, has fins that are filled with heated oils, which generates radiant heat as a result. Furthermore, in the case of ceramic heaters, ceramic is the heating medium that generates radiant convention heat.

In the case of an oil-filled one, the fins are filled with heated oils, which results in the generation of radiant heat. Furthermore, in the case of ceramic heaters, ceramic is the heating medium that generates radiant convention heat;
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.
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
In the case of a chilly grow room, the majority of us growers concentrate our efforts on heating the air inside of the facility. Nevertheless, one of the first things to try is to heat the soil/seeding rather than watering it in. In order to regulate soil temperatures between optimal limits, which are mostly 75-85 degrees Fahrenheit, these mats are used. When it comes down to it, heating the air is far more expensive than purchasing it. Some individuals use these mats exclusively as germination mats and never use them for anything else.
Make no mistake, though, because these mats are excellent for warming soil long after the germination stage. Our suggestions are as follows: Heater for aquariums, Soyon 300 Watt Another, less expensive option: Water Aquarium Heater and Thermometer by U-picks (30W)

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
It is possible that you may need to increase the number of lights in your grow tent at some time in the future. Winter does not hit us all at the same time. Nature is being slowly encroached upon by it. In order to keep the temperature optimal for the growth of your plants, you must ensure that you are adding extra lighting. This guarantees that you obtain the greatest benefit possible from your plants.
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
On very cold nights, you may wish to cover your plants with one or two pieces of frost protection fleece to save them from being damaged by the elements. This will save your plants’ lives by increasing the amount of heat they get. Taking the fleece off during the day will allow your plants to breathe more easily and receive more light. You can’t argue with the fact that lighting and ventilation are essential for the growth of your plant. I would like to use horticultural fleece instead of bubble wrap because it is considerably tougher and can survive even more exposure to ultraviolet light.
Take Care Of The Temperature
When the lights are on, the ideal temperature for grow tents is between 25 and 28 degrees Celsius, and when the lights are off, the ideal temperature is between 18 and 21 degrees Celsius. Because of these circumstances, it is critical to ensure that the temperatures are accurate at all times. However, by employing a digital thermometer in your grow tent, you can effortlessly do this difficult to sound job. Having grow tents is a godsend since it allows you to grow your favorite plants throughout the whole year, regardless of the weather.
Use An Oscillating Fan
With the help of electric heaters, you can keep your grow tent warm, but have you ever questioned if the heat is spread evenly throughout your grow tent’s interior? In this case, an oscillating fan will be used, which will help to evenly spread the heat around the space.
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 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.
- ** Do you want to get right to the point?
How to Increase Temperature in a Grow Tent
There are a plethora of options for generating heat in your grow tent. Let’s go straight to it. and see what happens.
Heating a smaller grow tent
- Heat generation in your grow tent may be accomplished in a variety of ways. Take a look at what we’ve done thus far.
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
The blooming stage of marijuana cultivation is when all of the magic takes occur. If the temperature is just perfect, the plant begins to emit its distinct aroma and the buds begin to grow enormous and densely packed. The optimal temperature for the blooming stage of the marijuana plant may vary slightly from species to species, but there is a basic rule of thumb for causing buds to grow in any marijuana plant species. It will blossom in the late summer and early fall if marijuana is cultivated seasonally outside, when the temperatures are beginning to cool off a little.
- For the flowering/budding period, I want my plants to be kept at a temperature between 20 and 24 degrees Celsius on average.
- Some lights, as noted at the outset of this piece, will generate heat as a result of their operation.
- Whether you choose high-pressure sodium lights, compact fluorescent bulbs, or LEDs, they will all generate some heat.
- Keep in mind that high-intensity lighting may cause the tips of your plants to burn.
- As the plants develop, you will need to change the height of the lights to accommodate their growth.
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. The room will be completely darkened as a result of this. 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.
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 to deal with your grow tent getting too cold
Winter has finally arrived! As the days go shorter and the temperatures continue to decrease, indoor gardeners may find their tent temperatures become too low for ideal development conditions. What should you do in this situation? Listed below are some useful hints.
- 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?
