Grow tent gets sudden heat rise due to multiple reasons. We need to learn about how and what turns to grow a tent into a heat buildup. Sometimes, ventilation goes wrong, and heat traps in the tent.
HVAC isn’t making up to par probably caused by the surroundings’ hotness. If the surroundings are hotter, the cooling system will have to do more to cope with it.
Sometimes, there are multiple sources of heat within the tent that could raise the heat level in the grow tent due to the least ability to cool agents to neutralize it. Lacking proper insulation might also be the reason behind the possible detrimental situation in the tent.
These are all possible reasons behind the uncontrollable condition of heat in grow tent. Heating control is necessarily needed to be controlled because heat will keep building up and it could be detrimental for plants.
If the heat growth is slower then it will impact plants through stunted growth and water consumption would be increased. To avoid any probable damages, the system needs to be cooled down. Here are some efficient methods to keep grow tents cool and feasible for plants.

List of Top 20 tips to let you know How to Cool a Grow Tent Effectively in 2021
Air Conditioning
This is the simplest and easily accessible method to turn temperature feasible in grow tent. If your setup is smaller then a small air conditioner would be good to accommodate but if it is bigger then an industrial-grade cooling system would be needed and air conditioning should be bigger.
This is the easiest way to avoid overheating in grow tents and a probable solution to keep the temperature low. Electricity usage might get higher because consumption and long-term usage will be heavily burdened to render tent cool.
Carbon Dioxide Use
The use of Carbon Dioxide will garner multiple benefits for plants. Carbon Dioxide is the basic unit for plants. When plants are near carbon dioxide, they grow properly.
The temperature of plants also gets lower due to carbon dioxide. Hot and bright light growers should prefer to use carbon dioxide because it pairs up better in those situations to lower temperatures. But the use of carbon dioxide could also be tricky.
So, the grower should be having a better understanding to use carbon dioxide in grow tents because PPM level stability is necessary for tents to avoid levels too high or too lower.
Inline and Exhaust Fans
Inlet and exhaust fans are the conventional and most feasible solutions to render grow tents cooler. They ensure that air is pushed inside and pushed outside. Fans solution ensures movement of hot air and constant flow of fresh air in the tent.
All the hot air accumulated inside the tent exhausted outside and inside grows cooler. A well-managed and set scenario of inlet and exhaust fans is enough to ensure coolness inside grow tent. Grow tent also remains intact from damages caused by hot air.
Grow Lights Heat Vents
Heat vents ascertain grow light to come out of the mainframe of lights. As the hot air is lighter in weight and rises upward, heat vents are placed in such a way to disperse outside. Grow lights with proper heat vents can do an amazing job to arrange hot air dispersing outside.
Grow lights with a compact body and no heat outlets should be avoided. Heat can build up inside grow tent and could be detrimental for plants. Grow lights with vents on all sides should be preferred.
Ventilated Glass Panels
Ventilated glass panels will ensure to provide more vents to expel hot air from grow tents. LED grow lights are probably built to offer vents on glass panels. This would be of extra advantage to ensure the exit of hot air.
Vents on glass panels also promote the longevity of LED grow lights because life span will be increased due to avoidance and vexation of heart damage.
Water Cooled Lighting Systems
A water cool lighting system is rarely used and seen. These are great to keep grow tents cool. Grow lights are one of the basic units of rendering inside of grow tents hot.
When the water-cooled lighting system is used, the heat of grow lights is controlled, and ultimately temperature gets lower. Water lighting systems are also better than air cooling systems to control temperature.
Clip-On Fan
This is one of the best grow tent accessories to purchase and tends to offer multiple benefits. These are extremely lightweight devices and can also be clipped on grow bars.
Fans encourage decreasing temperature and steady breeze inside tents because the breeze is a great natural source to lower temperature and plants’ branches get stronger.
Few bucks are enough to ensure clip-on fans at your service are in great value addition to cool grow tents. Small insects and pests also stay away from plants. For better growth and survival of plants, clip-on fan investment is worthy.
Timers
Timer setting is something that needs to be perfected over the time period. Once you are experienced enough to use grow lights for temperature reduction, you will be mastering to lower temperature.
Plants are also needed darkness equally as lightness. Effective timers can ensure to create a helpful cycle of coolness and warmness. This will benefit by reducing the time length of hotness and plants will keep getting timely coolness.
If your grow light setups aren’t really cooperative, you can set an alarm on your cellphone to manually process to the best feasible way.
Effective Circulation
Good air circulation is a positive approach to cool down the internal temperature of grow tents. Grow tent will not be needed any extra approach to a lower temperature.
Effective circulation offers an abundance of growth output to enable a lower temperature process. A carbon filter will necessarily be needed to avoid a bitter smell.
Night-Time Light
This is a simple efficient activity. Temperature is probably lower at night than day. Grow lights use at night will compensate the situation accordingly that inside temperature is lower as the outside is bearing the same situation.
This will avoid extra push on inside and outside temperature. Control inside grow tents get better and reversal of light in day-night could be rendering effective way to control temperature.
Relocation of Tent
Excessive heat exposure can be avoided by replacing tents from one place to another place on the temperature level. Grow tent in the basements could be great because it could be near to air vents if you have employed central air conditioning.
Placing near an open window could also be rewarding. Cool seasonal climates would be more advantageous when placed at open windows. Ducting routes will also be easily allowed.
Switch from HPS / HID Grow Lights to LED Grow Lights
HPS and CMH lights run heavy on hot lights. On the other hand, LED lights are cooler and keep the temperature inside grow tent quite maintained. LED lights also come with vents that help to cool inside any grow tent.
Relocate Hydroponic Equipment
If the growing process is done hydroponically, then filtration, pumps, and other electronic equipment can be relocated. Relocation of these extra types of equipment can be done by using extension cords or extended pipes.
Considering them out of tents as much as possible will be beneficial to reduce the temperature of grow tent. All methods are having their own builds to serve the purpose. This is an art or science to decrease the temperature inside tents.
Optimization of Ducting
This could be a turning point to lower the temperature inside grow tents but maximum growers avoid this method and experience optimized hot temperature inside grown tents.
For every 90 degrees value, a clear calculation is that fan has to perform 5% harder than it usually performs. Briefly, excessive use of bends and turns in ducts will automatically render fans less effective.
It results in poor air travel inside and outside the grow tent and the temperature will ultimately be increased. So, the grower needs to ensure that the duct is having the least bends and turns. It will perform efficiently for both intake and exhaust ducting.
Avoidance of Low Humidity
Humidity Level and temperature are having a direct connection with each other. The relation would be frequently there when the location is confined.
As the humidity level lowers, the temperature will get higher. If the humidity level is lower, it might result in higher temperatures within grow tent.
Ideally, 60% humidity is best for growing plants and 40% for grown plants. So, raising the humidity level is essentially important to support the growth of plants.
Perfect Structure
Issue of temperature would be solved if you purchase structure of grows tent by yourself. Start using grow tent by growing a lower number of crops. The overcrowded growing strategy of crops won’t be ideal.
We know carbon dioxide is of extreme importance for plants’ growth but when you grow a crowd of crops, some plants produce high levels of oxygen. This will have resulted in a higher temperature level. Small pots can also be employed when planting.
The humidity level will be controlled due to the least evaporation. Plants will remain healthy and overheating would be reduced. The purpose of all that process is to ensure that the internal temperature of the grow tent is feasible for the plants and doesn’t create any chaos by raising the temperature.
Light Mover
Light is the biggest source of temperature. When lights are on, the temperature value will probably end the uprising. To overcome temperature due to lights, light movers are used to dispersing light in the area.
This will stop the accumulation of light and heat in one place. A greatly built light mover will spread an equal amount of light throughout the place and you won’t be facing hotness growing in the tent.
Lighting resources will also be handled by a light mover. You won’t be needed any extra lighting to enlighten grow tent.
Icebox Intake
Icebox intake is also a good process to cool grow tent but this will need extra hard work. This is the best solution. This process will need constant replenishment. You can also create your icebox intake.
Good Insulation
Insulation is used to trap heat in the tent but there is no issue with it if the ventilation is of par level. Insulation should be regarded as a solution to lower the temperature of the tent.
If the tent is exposed to the variable condition of temperature then the insulation method is an efficient approach for keeping grow tent cool.
Water Chillers
Air Conditioning, Carbon dioxide, and other methods might be hefty to employ and expensive. Water chillers can make up for those expensive methods to sort out the higher temperature of grow tent.
Water chillers are electric devices that work through absorbing moist vapors and render coolness and a chilled environment. The water-cooled chillers and the air-cooled chillers are two methods that could be employed and later one is cheaper but less effective.
We will also suggest water chillers. Water reservoir and evaporating system come with it to lower the temperature of surroundings. We know lower humidity means higher temperatures in grow tents.
These devices keep the humidity level higher. With waters-based chillers, the chance of decreasing humidity levels goes down to a minimum level.
Conclusion
Keeping grow tent cool is important for fruitful results. We can see from our guide that there are multiple solutions. There is no perfect solution for lowering the temperature of grow tent.
Every solution also confers some incline for another way to render the best service. This wouldn’t be wrong to say that lowering the temperature of grow tent is more an art or science. If the easier method is not veritably employing to serve a purpose, then go for methods like dry ice.
Carbon dioxide is a byproduct of dry ice and we know about the importance of carbon dioxide for plants. Ice will act to cool the temperature of grow tent. It might not be easy to employ but it could be worthy of garnering effective results.
Lastly, we will suggest you find a match-make and find the best feasible solution through our guide. Employing the best and suitable method will bear fruitful, healthy, and quantitative results. Keep your hopes high for the best results.
