How To Keep Temperature Down In Grow Tent

9 Methods To Lower Temperature In Your Grow Tent (2022)

Maintaining an appropriate growth environment in your grow area is one of the most difficult aspects of growing cannabis indoors, and it may be quite difficult. It’s also the most critical factor to consider. It’s no surprise that I receive a large number of inquiries from farmers seeking assistance in decreasing their grow tent temperatures. If you want to reduce the temperature of your grow tent, there are numerous practical methods you may do. For example, moving your grow tent to a cooler part of your home, switching from an HPS to an LED grow light, and ensuring that your grow tent fan is pushing air out the window rather than into the room where your tent is placed are all good ideas.

Just to be clear, the best temperature range for growing cannabis is between 70 and 80 degrees Fahrenheit, or 21 and 27 degrees Celsius.

It is critical to maintain consistent temperatures in your grow tent in order to minimize plant stress.

To begin, I’ll discuss the most practical techniques of decreasing grow tent temperature, and then I’ll discuss the less practical ones:

Method 1: Relocate Your Grow Tent

Consider relocating your grow tent to the most comfortable part of your home. For example, if you have central air conditioning, you might want to consider your basement or a location near some air vents. You should also think about putting it near windows that are open. Your grow tent will be able to take advantage of cooler seasonal conditions if it is located near open windows. It will also make it much easier for you to run your ducting from inside the tent directly out the window.

Method 2: Route Grow Tent Ducting Out The Window:

The objective of the inline fan should not be defeated by merely blowing the air from your grow tent into the room where your grow tent is placed; otherwise, the fan will be ineffective. In order to counteract the negative pressure caused by your grow tent’s inline fan, you must draw air from the room where you have set up your tent and draw it back into it through your grow tent’s inline fan. You should take your ducting, or purchase extra ducting if required, and direct it out a nearby window to exhaust the heat.

Method 3: Turn on Your Air Conditioner:

Maintain a cool environment in the room where your grow tent is positioned. The most straightforward method of accomplishing this is to open a window during the colder months or to get a portable air conditioner to keep the area cool. Consider putting the portable air conditioner inside the grow tent if that isn’t enough to alleviate the problem. When the inline fan blows out hot air and generates negative air pressure in your grow tent, the air in this chamber is drawn back into your tent, causing the air to be drawn back into your tent.

Keep in mind that if the temperature inside your tent is 85 degrees Fahrenheit and the temperature of the external air being drawn into the tent is only 80 degrees Fahrenheit, the temperature differential will not be sufficient to cool the tent down.

The temperature of the replacement air must be in the low 70s in order to raise the tent temperature from 85 degrees to the mid-upper 70s.

Method 4: Add CO2 to Your Grow Tent

The addition of this simple-to-use CO2 bag to your grow tent will not really reduce the temperature, but it will have the same effect. Cannabis plants are able to survive temperatures that are far higher than normal when exposed to excessive CO2 levels. How much additional heat can cannabis endure when the CO2 level is elevated? A temperature range of 85 to 86 degrees Fahrenheit would be ideal for growing plants. This is in comparison to an usual temperature range of 70 to 80 degrees Fahrenheit in the absence of CO2.

Method 5: Make an Ice Box (with ice or dry ice):

This strategy will need a little ingenuity, but it is effective if you are willing to put out the effort. Because dry ice does not require replacement as frequently as wet ice, it will require far less maintenance. Using dry ice to reduce the temperature of a grow tent has the added benefit of creating CO2, which helps plants to survive at greater temperatures than normal (85 to 90 degrees Fahrenheit) as a result! What you’ll need is the following:

• Cold storage chest
• Ice or Dry Ice
• Oscillating fan
• Refrigerator

How to assemble: This may be as simple as putting your ice in a container or chest and directing an oscillating fan at it to cool it down. To be more imaginative, you may opt to seal the chest and cut a hole on either side of it, placing a fan in one hole and allowing air to escape through the other. A word about dry ice and carbon dioxide: CO2 is present at a concentration of 400 parts per million (ppm) in fresh air. Most gardeners agree that a CO2 concentration of 1,200 to 2,000 parts per million (ppm) is optimal for considerably improved plant yields.

• Concentrations more than 2,000 parts per million (ppm) can be harmful.
• Due to the fact that CO2 is heavier than air, you should have an oscillating fan operating to circulate the gas around the camp.
• When Using Regular Ice:If you don’t want to use dry ice, you might try making salt-ice instead.
• The use of salt allows the ice to remain frozen for a longer period of time.

Method 6: Make Sure Your Inline Fan is Strong Enough:

The inline fan in your grow tent is an excellent initial step in the process of eliminating heat from the tent. By clicking here, you can read my post on how to choose the proper size fan for your grow tent. Generally speaking, your inline fan should be replenishing the air in your grow tent once per minute, according to the rule of thumb.

You must also consider the lower fan power caused by bends in the ducting as well as the use of a carbon filter when designing your system. You might want to consider increasing the speed of your inline fan or purchasing a more powerful one if your current one isn’t powerful enough.

Method 7: Switch from HPS / HID Grow Lights to LED Grow Lights:

HPS and CMH grow lights generate a lot of heat. Consider upgrading to LED grow lights, which operate at a lower temperature and make maintaining the temperature of your grow tent easier. My time has been spent studying and updating a current list of the finest LED grow lights available, so please have a look at it if you are considering making the move to LEDs.

Method 8: Place Your Grow Light Drivers Outside Your Grow Tent:

The Mars Hydro TS-3000 (4×4 ft) and the TSL-2000 (2×4 ft) versions of LED grow lights, for example, feature replaceable drivers if you decide to make the conversion from HPS to LED grow lights. This is a significant advantage for growers that have difficulty decreasing the temperature of their grow tents.

Method 9: Relocate Hydroponic Equipment Outside Your Grow Tent:

If you’re growing hydroponically, you may be employing pumps, filters, reservoir chillers, or other electrical equipment that may be moved with the use of an extension cable or expanded pipes to accommodate your growth needs. Consider relocating as much of it as possible outside to help lower the warmth inside the grow tent. As you can see, there is no one perfect way for decreasing the temperature of a grow tent. There are several options. You may find one way to be more convenient or effective than another for you.

1. The dry ice approach is my personal favourite if the simpler ways don’t work for you.
2. While it may not be the simplest approach to use, I believe it is one of the most successful when it comes to raising the temperature of your grow tent environment to a comfortable range.
3. Learn how to determine the coverage of grow lights.

To reduce the temperature of the grow chamber; What you should do in order to prevent excessive temperatures from causing damage to your plant’s health

High Temperates Kills the Plant. Here is How-

What precisely occurs when the temperature in your growing room is too high? Answer: Temperatures have an effect on a plant’s capacity to photosynthesise, seed germination, and fruit/flower growth. Here’s why: Which, when taken as a whole, leaves you with less and lower-quality produce. To simplify things, here are some fundamentals concerning high temperatures in growth environments: First and foremost, grow lights function as warmers. LED, high-pressure sodium lamp, fluorescent lamp, plasma lamp, and every other type of light generating heater we can think of are all light emitting heaters.

1. The leaves and roots of plants are immediately affected by the high temperatures seen in grow rooms.
2. The heat from the leaves is removed through the evaporation of water via the Stomata, which in turn cools the plants.
3. While water is moving through the Stomata, the guard cells around it are activated by the high temperatures and conditions.
4. As a result, your plants will eventually cease to function due to a lack of photosynthesis.

How to Detect ‘Too High’ Temperature of Your Grow Space?

A great grow environment should maintain a constant temperature between 70 and 80 degrees Fahrenheit (21 and 26 degrees Celsius). This is what I mean by ‘uniform,’ which means that it should be the same across the contour. When the temperature surrounding the sources (lights) is greater, oscillating fans can be used to circulate the air. That is, however, the usual temperature range for fast-growing annuals in general. A slight increase in temperature may be beneficial as well, as long as you have something to protect the root zone, such as a water chiller.

• Ideally, a grow chamber should maintain a constant temperature of 70-80°F (21.1-26.6°C). It should be the same along the entire contour, and this is what I mean by ‘uniform’. You may use oscillating fans to circulate the air around when the temperature surrounding the sources (lights) is high. That is, however, the usual temperature range for fast-growing annuals in the garden or greenhouse. More temperature may be beneficial as well, provided that you have anything to protect the root zone such as a water chiller. Observe the plants for any of the following negative signs to be more convinced that the temperature is too high for them:

However, it is usually preferable to notice a problem with the temperature and surroundings of your plants before allowing them to wilt. A 3-in-1 moisture, light, and pH meter may be a useful addition to any kit. Here’s one of the most popular from Healthy Wiser. So to be clear, anything above 85°F or 90°Fhigh will be considered, and we will search for a solution throughout the remainder of this piece.

8 Actionable Grow Room Cooling Solutions

We have arrived to the center of the post, which is exactly what you are looking for right now. Here is a list of 7 quick and simple treatments for high grow room temperatures that are both simple and effective:

1 of 7: Boost Up the Air Exchange Rate

In an indoor growing environment, hot air builds quickly. It is possible that you have installed an input and extractor fan in order to remove the heated air. Increase the speed of this fan duet to increase the rate of air exchange in the room. You can manually change the fan speed every now and again, but there are programs available that can do it automatically and with pinpoint accuracy. My favorite is the recently released Titan Controls Kronus 4, which is my personal fave.

To get a better and cooler air exchange, one more effective advice is to gather the intake air from the coolest spot that is readily accessible close by. I’ve seen farmers use an air conditioner to chill the water they’re using as an input.

2 of 7: Have A Low-Strength Nutrient Solution

When the temperature is high, more water is absorbed by the leaves, resulting in a greater demand for water by the root system. As a result, they are compelled to consume additional nutrients. Furthermore, increased nutrient consumption is associated with an increased risk of plant toxicity concerns. This finally leads to their demise, though. In order to prevent this from happening, dilute the nutrient solution by a specific proportion (20 percent in most cases). All that is required is the addition of the determined amount of fresh water.

An air pump and some air stones should be included in the solution.

3 of 7: Enhance Air Flow

As a result of the high temperature, more water is absorbed by the leaves, which results in a greater need for water by the roots themselves As a result, they are forced to consume additional nutrients. Furthermore, increased nutrient consumption is associated with a greater risk of plant toxicity. In the end, this results in their death. Dilute the nutrient solution by a specific proportion in order to prevent this from happening (20 percent in most cases). All that is required is the addition of the calculated amount of clean water.

• The VIVOSUN 6′′ Clip-On Fan is the best oscillating fan for grow tents. Hurricane 18″ Wall Mount Fan is the best oscillating fan for a grow room.

4 of 7: Enhance Humidity

Humidity is the most apparent factor to consider when discussing temperature, and it comes in second place. In the same way, vice versa. They have an effect on one another, and you can cope with the increased temperature in a grow area by adjusting the relative humidity in the space. Now, how can you keep your grow tent cool by regulating the humidity in it? If the temperature rises in a curved space, relative humidity drops, according to the findings of a study published on Sciencing. Even if the temperature in your grow room is extremely high, you should be concerned if the relative humidity is also unusually low.

Now, here’s a fun fact: increasing the humidity level will not only prevent the plants from drying out, but it will also cause the plants to chill down.

In addition to increased humidity, there is a fall in temperature, which works to your advantage.

5 of 7: Switch Off or Dim A Few Light Sources

Many of us growers believe that putting the light sources above the plants’ heads will alleviate the temperature issues we’re seeing. However, the reality is that while this may reduce direct heat on the plants by a little amount, it will not reduce the temperature of the overall grow tent. What actually works in practice is to turn off 50% of your light sources for a period of time. If you have two, you may switch one of them off for a short period of time and it will not cause any problems.

It works well with high-pressure sodium lights. It is important to understand how to choose the proper wattage of lights for your indoor plants in order to avoid any heat concerns that may arise from the light sources.

6 of 7: Chill The Nutrients

Many of us growers believe that putting the light sources above the plants’ heads will fix the temperature issues we’re seeing right now. Although this may reduce direct heat on the plants by a little amount, it will not reduce the temperature of the grow tent as a whole. In practice, turning off 50% of your light sources for a period of time is effective. There will be no trouble turning one of them off for a short period of time if you have two. The Galaxy Grow Amp Ballast has a dimming feature that is useful if you want to take it one step further.

It is important to understand how to choose the proper wattage of lights for your indoor plants in order to avoid any heat concerns caused by light sources.

7 of 7: Using Air Cooled Hoods

The heat released by light sources and other forms of illumination is the most significant contributor to the increasing temperature in your grow room. So, why don’t you use a reflective hood that is air-cooled? It’s something that can remove up to 50-60 percent of the heat created by grow lights, depending on how efficient it is. There are versions, like as the Magnum XXXL, that do an excellent job of dissipating the heat generated by the light source. They are completely sealed and can be used in conjunction with duct fittings.

3 Bonus Tips

I’m confident that implementing a few of the aforementioned suggestions will assist to reduce the excessive temperature or, at the at least, let your plants live in a hot environment. Here are some additional extras to go along with these suggestions.

Run the lights at night

• Despite the fact that we are all aware of this, I stress on it more since it will help to keep the ambient temperature low.

Seal the entire space up

• If you are a grower who lives in a hot environment, this may be even more beneficial to you. Such a grower is more likely to use an air conditioner as well as a carbon dioxide generator to keep the environment cool. It is preferable to utilize a subterranean space since it acts as a natural thermal insulation. Aside: Plants in a grow room can withstand high temperatures and high carbon dioxide levels in the air.

Toughen up Cell Walls of the Plants

1. This will aid in the greater survival of plants, as well as the colonization of the root zones of plants, in the long run. A high-quality Silica Supplement for plants is essential in this process of toughening. Currently, I’m finding this one from Botanicare to be really beneficial

Hello, my name is John and I’m here! When I’m not busy working on my own company, you can find me wandering around my indoor plants, playing Call of Duty with my wife and kids, or hanging out with my friends and colleagues. John Terry’s most recent posts are shown below. (See all of them)

How To Cool A Grow Tent Without Wasting Tons Of Money

When it comes to growing cannabis indoors, heat is the one issue that almost every grower has to deal with. Growing marijuana in a small space, along with the heat created by grow lights and other equipment during the summer months, causes temperatures to rise much over what is considered safe for marijuana plants. If you want your plants to survive until harvest time, you must take action to combat the heat. Fortunately, there is a great deal you can do. For decades, growers have been able to successfully deal with heat-related issues.

Continue reading to find the most effective methods for keeping your grow tent cool, even during the warmest summer days.

How To Cool A Grow Tent

Based on your location, the temperature in which you reside, the sort of grow lights you are using, and a variety of other circumstances, you may have a significant heat problem or a very minor one. All of the ways for cooling your grow tent that are discussed here can make a significant impact in the temperature inside. However, most of them will not be sufficient on their own, unless you are dealing with a very little quantity of extra heat. If you’re dealing with a more complicated topic, you’ll need to mix numerous approaches.

More information may be found in “Do Grow Tents Prevent a Helicopter From Detecting Heat?”. Having said that, even if you do not have a significant heat problem, combining numerous solutions is always going to be the most successful, and this is precisely what we advise you to do.

Switch To LED Grow Lights

If you’re still using high-pressure sodium or high-pressure mercury vapor grow lights, it’s time to make the transition to LED. Or, at the absolute least, to the Children’s Miracle Hospital. Do not even consider using HPS or MH if you are just starting out in the business world. LED grow lights (and CMH grow lights as well) are simply superior than older HPS or MH grow lights in every aspect (except initial cost, though even that is fairly close these days). LED lights consume less electricity to produce the same amount of light, and they generate less heat.

Furthermore, you will not be need to update bulbs every two to three years.

If you want to save time and money, opt for the HLG grow lights, which are manufactured in the United States.

Spider Farmer is unquestionably the greatest, but if your budget is even more restricted, theViparspectra Pro Series lights are a good alternative.

Put Ballasts Or Drivers Outside The Grow Tent

If you are using high-intensity discharge (HID) lights and want to use them indefinitely, you may limit their heat output within the grow tent by placing their ballasts outside the tent. Because the ballasts generate a significant amount of heat on their own, placing them outside can be beneficial. You may also dim the ballast in order to lower the output of the lights as well as the heat produced by the ballast in itself. Even with LED grow lights, this might be a viable solution in some situations.

The Quantum fixtures and the Spyder type fixtures are both capable of doing so.

If you have an LED grow light with an external driver, you should be able to remove it from the fixture and set it outside the grow tent without difficulty.

Cycle Air In And Out Of The Tent

At the absolute least, you’ll want an exhaust fan and some ducting in order to do this. In addition, a charcoal filter will almost certainly be required. Furthermore, if you are utilizing a large grow tent, you will want an intake fan as well as a ventilation fan. Read our post on how to determine the size of fan you require. In order for my grow tent to function properly, I need to know what size fan I’ll need. Make use of the exhaust fan to remove the air from the grow tent. You could just vent it into the room, but it would cause the room to heat up, and you’d end up with an issue that was identical to the previous one.

• However, even in this case, it is preferable to use the ductwork to direct the air out a window or into the attic.
• A simple system for producing marijuana indoors.
• You should probably use a carbon filter to eliminate the stench from this air before releasing it into the surrounding environment to avoid spreading it further.
• Although you may place this carbon filter outside of the grow tent to save room, it is normally preferable to do so if at all feasible within the tent.
• Because cold air tends to settle towards the bottom of the tent, the intake should be located near the bottom of the tent.
• In order to draw fresh air into a larger grow tent, the exhaust fan will need to be very powerful, which means you’ll need an intake fan that can keep up with the exhaust fan in order to draw fresh air into the tent.
• Maintain a comfortable temperature in the room outside the tent.
• It is also possible to install an air conditioner directly in the tent (see below).
• The following are some considerations to keep in mind when doing ducting.
• Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the aperture at the end of the duct.

Pests can also enter through the ducting or the intake vent, in addition to being drawn in by the light. Consider installing a screen over each entrance to keep them out completely.

Run An Oscillating Fan In The Grow Tent

A minimum of an exhaust fan and ducting will be required to accomplish this. A carbon filter will very certainly be required as well. An intake fan will be required if you’re working with a large grow tent. Read our post for more information on determining the appropriate size of fan for your needs. In order to properly ventilate my grow tent, I must first determine the size of the fan required. Pulling air out of the grow tent using the exhaust fan is a required. You could just vent it into the room, but it would cause the room to heat up, and you’d end up with an issue that was identical to the one you were experiencing.

1. If you must use ducting, it is preferable to vent the air out a window or into the attic rather than via a window.
2. Inside marijuana cultivation at its most basic.
3. In order to avoid spreading the smell of this air around the globe, you should definitely use a carbon filter to eliminate it.
4. However, it is normally preferable to use this carbon filter within the grow tent in order to preserve space, unless it is absolutely necessary to do so.
5. In order to keep chilly air at bay, it’s best to place the intake near the ground.
6. As mentioned above, the exhaust fan for a larger grow tent will need to be very powerful, therefore you’ll need an intake fan that can keep up with the exhaust fan in order to draw new air into the tent.
7. Maintain a cool temperature in the space outside the tent.
8. It is also possible to install an air conditioner directly in the tent itself (see below).
9. The following are some considerations to keep in mind when doing duct work.
10. Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the aperture at the end of the run.
11. Consider installing screens over each opening to keep them out.

Put A Swamp Cooler In The Tent

Swamp coolers chill the air by evaporating the water contained within them. For this reason, they are often referred to as evaporative coolers. They are more efficient at chilling air than other types of coolers (such as regular air conditioners), but they also add moisture to the air they are used to cool.

If you need to boost humidity, a swamp cooler is a fantastic tool. However, if your grow environment is already too humid (or just perfect), you should avoid using a swamp cooler. Instead, use a conventional air conditioner to cool down.

Put An Air Conditioner In The Tent

This is the quickest method of bringing the temperature of the air within your grow tent down. However, it is only something you would want in a larger tent because it takes up a lot of room and significantly cools the air. It also helps to reduce the humidity in the grow tent. An air conditioner in a room outside the tent will usually be sufficient in most situations. As a result, it helps to chill the air outside the tent, which is then drawn inside the tent via the intake.

Run Lights At Night

You may cool down the air inside your grow tent in the shortest amount of time by doing so. However, because it takes up a lot of room and significantly cools the air, it is only useful in a bigger tent. The humidity level in the grow tent is reduced as a result. An air conditioner in a room outside the tent will usually be sufficient in most circumstances. By cooling the air outside the tent, it allows it to be sucked into it via a small input hole.

Move The Grow To The Basement

Heat increases, as we have already established. As a result, the lower levels of your home will be significantly colder than the top levels. If your grow tent is presently placed upstairs or elsewhere, relocating it to the basement will result in a somewhat cooler ambient temperature, which will make it simpler to keep your tent cool while it is being used.

Cooling A Grow Tent: Final Thoughts

Heat increases, as we have already shown. As a result, the lower levels of your home will be significantly colder than the higher levels. In the case of a grow tent that is currently placed upstairs, relocating it to the basement will result in a somewhat cooler ambient temperature, which will make it simpler to keep the tent cool.

During the sweltering summer months, some indoor cannabis farmers would even close their doors completely.

Although switching to outdoor cropping is an option for some, for the majority, indoor marijuana is the only option. Reader, don’t be afraid of the sun! In order to assist you cope with the heat of summer, we’ve compiled a list of 12 suggestions for indoor gardeners.

USE AIR-CONDITIONER

An air conditioner is a simple and elegant answer to the excessive heat that might build up in a grow room during a hot summer. If you happen to reside in a cooler nation, on the other hand, your home is likely to be equipped with central heating rather than an air-conditioning system. A portable air conditioning unit will suffice, and you may be able to locate one at your local grow store if one is not already available; if not, you will almost certainly be able to purchase one online. The sole disadvantage of utilizing air conditioning is that it increases the amount of money spent on electricity.

ADD CO2

The addition of CO2 has been shown to increase the size of buds and increase marijuana output. It is ideally suited for commercial grow operations, and it is particularly popular among more experienced growers who want to maximize their yields. Furthermore, increased levels of CO2 allow for a higher temperature in the growing environment, which is a good approach to take advantage of higher temperatures. However, for the home grower who is likely to be sleeping in the bedroom next door, proceed with caution and stick to a simple passive system rather than experimenting with CO2 tanks and other high-tech equipment.

AIR-COOLED HID Lights

HPS and MH lamps from the past generate a significant amount of heat in addition to light. By air-cooling those HID bulbs, you can keep the heat at bay and your plants flourishing all year long. An extra fan and some ducting connected to an air-cool reflector are all that’s necessary for sucking up the heat generated by the grow tent.

GROW BY NIGHT

Growing at nightfall is a simple way to get around the high temperatures of the daytime. The temperature at night is naturally lower than the temperature during the day, and because your grow light regulates the day-night cycle for your plants, they will never know the difference. Additionally, operating the electricity off-peak should result in a reduction in the electricity cost.

CORDON OFF THE GROW OP

It is usually simpler to maintain ideal environmental conditions in a grow room that has been well-insulated and adequately sealed off. The goal is to keep the impacts of the weather outside from entering the building and to create a comfortable indoor microclimate.

KEEP THOSE BALLASTS OUTSIDE THE GROW TENT

It is recommended that you put your ballasts, control boards, and other electrical contacts on a wall outside of the grow tent to prevent them from being damaged. Practicing good housekeeping when it comes to electronics will not only help you save a few degrees on your thermostat, but it may also save your life. Heat is generated by all ballasts and grow equipment, thus keeping them out of the grow area and off the floor is the best configuration.

INTERIOR AIRFLOW

If you have a small grow display, adding an oscillating pedestal fan, and/or some clip-on fans if space is limited, can make all the difference in the world during a summer heat wave. A mild wind will aid to keep cannabis plants cool and stiff by keeping them from wilting.

ADD A BUCKET OF ICE

Desperate circumstances need the use of desperate tactics. If money is limited and the heat is on, the most cost-effective approach to drop the temperature a few degrees is to use a bucket or two of ice.

You may just fill up a few empty 2L plastic bottles with water and place them in the freezer for a few hours, or if you have an American Freezer, dump the ice cube dispenser into a bucket and refill it with water until it is completely frozen.

DUCTING

If your ducting is kinked or bent, it will place a larger strain on your fans, which will decrease their efficiency. Smooth out the ducting and avoid any twisting or bending as much as possible. It is certain that heat will build up if the ducting connecting your air-cooled reflector or outtake fan is rough and improperly linked. Similar to this, sagging ducting on an intake fan would restrict the amount of fresh air that can be drawn in via it. Get yourself a new roll of duct tape to use to fasten connections and keep the ducting in place.

USE A DIMMABLE BALLAST

During the hot summer months, dimmable ballasts provide additional flexibility for the interior environment. If the temperature rises to dangerous levels, it may be necessary to reduce the power of the grow light. Of course, this will result in a reduction in lumens as well as a fall in temperature, which will result in a reduction in yields. Although dimmable ballasts are not a perfect answer, they can allow for a scaled-down indoor summer grow show instead of a complete shut down of the facility.

INVEST IN LED LIGHTING

LEDs are the ideal solution for the indoor gardener who is adamant on cultivating indoors even when the weather outside is downright Martian in its rigor. The advantage of LED lighting is that the vast majority of the energy is turned to light rather than heat, resulting in a more comfortable operating environment. As of right now, the only significant disadvantage of the current generation of LED systems is their cost. When it comes to long-term investments in your grow operation, LEDs are a fantastic choice.

So that’s your lot, and if the dozen or so techniques listed above don’t assist you to lower grow room temperatures in a hot summer, you can always migrate to Alaska, where you’ll forget what it’s like to be heated in a short period of time, especially since they now have legal marijuana.

How to Reduce Heat Inside a Grow Tent

When you are first starting out in a new location, it can be challenging to maintain the optimal temperature for your cannabis plants. Because of the restricted airflow within a grow tent, it might be even more difficult to regulate the temperature inside. It can be difficult to keep the heat levels under control, which is why we’ve put up this guide to assist you with the procedure.

Are High Temperatures Bad for Cannabis Plants?

The ambient temperature may be significantly higher than the 70 degrees Fahrenheit that your plants find pleasant if you are growing marijuana in a hot location or in an area where heat cannot disperse, causing heat stress in your plants. An increase in temperature can cause your cannabis plants to grow more slowly, produce less, and possibly die if the temperature continues to rise. Heat is a major worry throughout the flowering phase of cannabis plants, as well as for those who grow cannabis hydroponically, when the roots are exposed to the elements (as opposed to being protected by a pot and layer of dirt).

To your advantage, there are a variety of procedures and supplements that may be utilized to manage temperatures and minimize heat damage to your cannabis plants. Examine the following easy methods to begin lowering the heat temperatures inside your growing space right away.

Using Oscillating Fans Inside Grow Tents

While fans will not completely reduce the heat within your grow tent, they will assist you in better circulating the air inside. Keeping your plants as near to the sun as possible, where the majority of the heat is created, is essential in the conventional growing environment. To dissipate the heat generated by your lights and to keep your plants cool, consider using an oscillating fan.

Ceiling or Floor Vent for Grow Tent Exhaust?

Because of the way heat rises, deciding whether or not to put your exhaust fan in the ceiling vent of your grow tent can make a significant impact in your growing results. The ceiling vent will allow hot air to be pulled out while passively drawing air from the floor vent, which will be cooler because it is higher in the room. This simple setup tweak may make a significant difference in the amount of work necessary to keep the temperature inside your tent under reasonable control.

Use a Cooling Humidifier

The use of a humidifier with a cooling effect, such as Vick’s Cool Mist Ultrasonic, inside your grow tent will assist to lower temperatures even further while simultaneously raising humidity to acceptable levels, as shown in the chart below. However, you will want to be cautious not to let the humidity to rise too much, since this might unintentionally raise temperatures. While a humidity level of roughly 40% is regarded best for vegetative marijuana plants, greater humidity levels are preferred for seedlings, which benefit from lower humidity levels.

Use Buckets of Water, or Ice

Water buckets strategically placed around your growing space can both aid to boost humidity levels and lower the heat inside your grow tent, which will benefit both of you. Ice cubes or frozen water bottles can also be used to fill the buckets with cold water, which is preferable to using hot water. Heat will be absorbed by the bucket of water, which will function as a heat sink for the inside of your tent. This strategy works well in conjunction with the use of oscillating fans within your grow tent.

Control the Temperature Outside of the Grow Tent

The temperature inside your grow tent will naturally be a few degrees warmer than the outside temperature due to the nature of the material. As a result, you should always strive to increase airflow in the surrounding regions, ensuring that all of the heat created by your grow tent is dissipated. As a result, it is preferable to connect your exhaust fan directly to an exterior window, as this will prevent any heat buildup from occuring near the growing region. It may also be necessary to employ additional oscillating fans or air conditioning to keep temperatures outside of the grow tent within acceptable ranges.

Optimize your Marijuana’s Day and Night Cycle

The majority of farmers will also opt to operate their lights for the whole 24 hour period, rather than the traditional 16 hours of light followed by 8 hours of darkness. Running your light for a full 24 hours will result in a 30 percent increase in the amount of electricity used as well as the total quantity of heat emitted by the light. While this may not be a major worry for many growers, it is vital to be aware of the declining returns that are connected with this situation. In other words, your plants will not develop 30 percent more quickly than they would if they were just exposed to 18 hours of light.

It is common for temperatures to be at their greatest during the daytime hours.

The additional benefit of using this strategy is that your energy bills will be lower as a result of the lower cost of electricity during non-peak periods.

Supplements to Protect Against Heat Stress

It may surprise you to learn that a variety of supplements are quite helpful in mitigating the negative effects of high temperatures on your plants by assisting them in dealing with heat stress. Supplements such as these should only be used as a last option in order to minimize the amount of moving components in your garden and to avoid creating unnecessary complexity. But if you have tried all of the procedures above and are still experiencing high temperatures inside your grow tent, these supplements may be just what you need to keep your plants from suffering more harm from the high temps.

Silica for Cannabis Plants (Potassium Silicate)

Silica supplementation is beneficial for a variety of environmental conditions that your plants will want to avoid, and it may assist your plants in dealing with the stress associated with higher temperatures. Because of the enhanced resistance to stress, your garden will be able to thrive at temperatures that are above normal without suffering any harmful consequences. Supplementing your cannabis plants with silica has a variety of other indirect benefits, such as a mild corrosion to the leaves, which makes it less appealing to pests and other insects (if you were growing outdoors).

Use Supplements for Root Health

If you are growing cannabis hydroponically, the roots of your cannabis plants will be exposed, making them much more sensitive to greater temperatures than they would be otherwise. As soon as temperatures reach uncomfortably high levels, the condition of the roots begins to degrade. Visually, this will become apparent, and if you touch the roots, they will feel as though they have been covered with slime. The administration of a root health supplement may have a significant influence on the vitality of your plant’s roots, and can even help them to recover from their state of ill health.

Heat Resistant Strains

Believe it or not, certain strains of cannabis are really more heat tolerant than others and can withstand greater temperatures than others. Typically, Sativa-dominant strains are preferred by high-temperature growers, and this gene may be found in many famous marijuana breeds. Choosing one of these strains should be regarded a last resort for those who have been unable to maintain temperature control within their grow tent.

Question: How To Lower Temperature In Grow Tent

Use an oscillating fan or a clip-on fan to circulate the air. Getting stagnant air flowing around in your tent might be all that is required on occasion. The majority of folks have one or two tiny fans laying around their homes. Alternatively, you could simply get a clip-on fan while you’re here. They’re inexpensive, take up little space, and will aid in the dispersal of heat in the room.

How hot is too hot for seedlings?

The overall answer is roughly 90 degrees Fahrenheit, with a few outliers to the generalization. This implies that when temperatures reach over 90 degrees Fahrenheit and remain there for an extended period of time, leaves wilt. When the temperature is high, water evaporates more quickly into the atmosphere, depleting a plant’s water supplies.

Is 80 Degrees to hot for a grow tent?

The usual answer is somewhere around 90 degrees Fahrenheit, with some outliers. If temperatures increase above 90 degrees Fahrenheit for an extended period of time, the result is wilting foliage. During periods of extreme heat, water evaporates more quickly into the atmosphere, depleting a plant’s water storage capacity faster.

Can you leave your grow tent open?

How to Cool Down a Grow Tent [Cannabis] Home Cultivation Tips 2022

Cannabis cultivation at home may be a pleasant experience. One of the most common problems that beginning growers have is maintaining the temperature inside their grow tent under control. Cannabis must be cultivated in a precise temperature range in order to provide the highest yields possible. If the temperature is too low, the plant’s development will be slowed or stopped altogether; if the temperature is too high, the plant will be stressed, and the quality will be negatively affected. Maintaining the temperature of your tent as the temperature begins to climb is critical to the overall health of your marijuana plant.

Let’s talk about why heat is bad, what indicators to look for that your plants are becoming too hot, and how to adjust the temperature of your grow tent to produce superior cannabis.

Why heat is bad for your cannabis grow

When cultivating cannabis, the optimal temperature ranges between 70°F and 85°F (20°C and 30°C). This is one of the reasons why growing indoorsinside a grow tenthas become so popular; the weather is no longer a consideration. The aspect that takes a little bit of consideration is how to keep your grow tent inside this temperature range. The temperature of the surrounding room and the quantity of heat emitted by your lights are the two most critical aspects in determining the temperature within the tent.

When the temperature in the grow chamber is below or above this range for an extended length of time, you will have difficulties.

It is necessary for plants to breathe and perspire in order to keep their biological processes running and to feed on nutrients.

In your plant, terpenes are essential oils that give it its distinctive flavor and scent.

So what are the symptoms of heat stress to look out for?

Plants, like people, will sweat in order to cool themselves off. Nevertheless, if your plants begin to experience a lack of moisture, the leaves may begin to dry up and may eventually fall off. It is important to search for concerns if you notice your leaves curling up at the tip and margins of the plant. In extreme cases, the leaves will dry up, lose their color, and eventually die as a result of the high temperatures.

Foxtailing cannabis flowers

When a plant responds to heat stress by producing new flower development, this is known as foxtailing. Because of this, the fresh blooms will develop on top of the more established buds, which isn’t the best situation. Despite the fact that you might think “great, more flowers!” these new buds will be less powerful than the ones that were previously developing. Your ultimate harvest will consist of a mixture of ripe and immature buds, which may or may not be what you want for your final product depending on your preferences.

Fixing Heat Stressed Cannabis

When a plant responds to heat stress by producing new flower development, this is known as foxtail. In an unfavorable situation, these new blooms will develop on top of the more mature buds. You could think, “Yay, more flower buds!” but these new buds will be less powerful than the ones that were already developing when you first saw the plants. Because your ultimate harvest will consist of a mixture of mature and immature buds, it is possible that your final result will not be what you intended.

Anatomy of an Indoor Cannabis Grow Tent

Some growers that have ample space may be employing a specialized room for their operations. Grow tents, on the other hand, are the most effective method of growing cannabis inside for many tiny producers.

Grow tents are designed to keep the perfect atmosphere for cannabis cultivation at a constant temperature. Humidity, heat, and light will be kept in by a high-quality grow tent, preventing damage to your house or rental property.

Types of Grow Lights

Choosing the right grow light for your tent will have the most influence on the temperature within the tent. There are two primary types of grow lights: high-intensity discharge (HID) lamps and LED lights.

Choosing HID Lights for Your Grow Tent

Choosing the right grow light for your tent will have the most influence on the temperature inside of it. High intensity discharge (HID) and LED grow lights are the two most used types of grow lights.

Choosing LED Grow Lights for Your Grow Tent

LEDs (Light-Emitting Diodes) are electronic devices that emit light. LEDs are a more recent and generally less expensive alternative to high-intensity discharge lamps (HIDs). LED grow lights also generate far less heat than conventional types of lighting. Your grow room will become hotter as a result of the use of either sort of light. It will be required to have an exhaust fan installed in order to keep the space from becoming too hot.

Cooling with a Mini Inline Fan

Those who work with light-emitting diodes know what I’m talking about. Compared to high-intensity discharge lamps, LEDs are a more recent and often less expensive option. In addition, LED grow lights generate far less heat than conventional types of illumination. Your grow environment will get hotter as a result of the use of either sort of lighting. In order to keep the room from being overheated, an exhaust fan will be required.

Equipment for cooling air inside a tent

An inline fan is the most important piece of equipment you’ll need to keep a heated tent cool throughout the summer. These fans are responsible for two tasks. First and foremost, they assist in air circulation by drawing in new air that contains CO2 and exhaling oxygen. First and foremost, they aid in the regulation of the temperature within the grow room by bringing in cold fresh air and releasing heated air as needed. Maintaining the temperature of your grow room using simple oscillating fans might also aid to keep your plants cool.

They also aid in the hardiness of your plants.

Because of the way it dances in the air, the stalk grows in strength.

The most effective method is to keep the fan running or to direct it indirectly towards the plants.

Keeping a Cool Grow Tent

The CFM rating of your inline fan will be provided. This will tell you how many cubic feet of air can be transported in a minute based on your speed. CFM is an abbreviation that stands for Cubic Feet per Minute. The first thing you must do is determine the volume of air that will be contained within your tent. This is accomplished by the use of the formula Length x Width x Height.

Here’s How:

Take, for example, a grow tent that is 3′ x 3′ x 6′ in size, which is rather small. 3 times 3 times 6 equals 54 cubic feet. The most effective ventilation will be achieved by using a fan with a larger CFM rating than the volume of the tent or room in which you are working. The reason for this is because you don’t want your ventilation fan to be running at full power all of the time, as this might cause it to become overheated and prematurely wear down your ventilation fan. Another rationale for utilizing a faster rate fan is to compensate for the efficiency loss caused by the use of a carbon filter.

When air is forced past this filter, the fan has to work a little harder to do its job.

When it comes to the ventilation fan itself, the dimension refers to the size of the duct.

The majority of 4′′ ventilation fans have a CFM rating of around 190.

Many fans today will come with some type of speed control, allowing you to fine-tune the amount of power they consume. If you find that your tent is becoming a bit warm when the lights are turned on, you may raise the strength of the fan to allow it to expel warm air even more quickly.

Choosing the right spot for your indoor grow tent

A grow tent used inside your house will have a significant impact on the temperature within the tent depending on where it is placed. Although an uninsulated garage may appear to be a convenient location for keeping it out of the way, you must ensure that temperatures inside the tent do not go below 60°F, or your plants may cease to develop completely. Alternatively, your attic may be significantly warmer than the rest of your house. When the grow lights are turned on, the temperature within the tent will typically rise beyond the temperature of the surrounding environment outside the tent.

Tips for Keeping your grow cool

Additionally, your attic may get warmer than the rest of your house. In most cases, when the grow lights are turned on, the temperature within the tent will rise to a level greater than the surrounding environment.

How to Maintain Your Grow Room Temperature

You should now have a clear understanding of how to manage the temperature of your growing environment. Even the most experienced growers may find this to be a difficult task, so don’t be put off by the prospect. It doesn’t matter if you’re growing hydroponically or in soil; every grow place will be a bit different.
