Every condition in your Grow room needs to be kept at an optimum level. Temperatures are a common problem that you will have to deal with.

Appliances will produce some heat, and also, you will get excess temperatures from outside. All this will make the temperatures of your Grow tent unbearable.

And that’s why you need to cool them down.

In this article, we will discuss with you 8 simple cooling solutions for your Grow tent.

But before we do that, we will first discuss a few things you need to know about high temperatures in a Grow tent.

Let’s get started.

Ambient temperature is the temperature that is conducive for your plants to thrive well in a Grow tent. It’s affected by the temperatures inside and outside the Grow tent.

It’s the optimum temperature that shouldn’t be allowed to go down or high. If it goes, either way, it will affect your plants.

As a grower, you need to ensure that the temperatures are maintained at their optimum at all times. This will help your plants to breathe and thrive appropriately at every stage.

At different phases, you also need to ensure that the temperatures are maintained at a certain level. In every phase, ensure the temperatures are within their limit.

The temperature level in the germination stage might be harmful to plants during the vegetative stage. This is why you always need to be keen and ensure you maintain the right temperatures at all times.

Seedlings Phase 75-95°F (21-33°C) 

Germination and seedling stages require a higher temperature than all other stages. At this phase, your plants are growing at a high rate hence the need for heat.

However, to get the best out of this stage, the temperatures shouldn’t go beyond 95°F. If it does, the seedlings will start withering.

At this stage, the seedlings are delicate, and any temperature changes will cause huge damage to the plant. So, if you wish to get the best out of your plant, ensure the temperatures are maintained within the desired levels.

Vegetative Phase – 70-85°F (20-30°C) 

Vegetative phase is a stage at which plant is maturing. The leaves are blossoming, and branches are developing. This phase is characterized by continuous growth.

During the vegetative stage, your plants would require a higher level of warmth. Basically, you should keep the temperatures between 20 degrees Celsius and 30 degrees Celsius.

Flowering Phase – 65-80°F (18-26°C)

At the phase, your plant starts developing buds and producing yields. When your plants hit at this stage, its good to lower the temperatures in the Grow tent.

Lower temperatures help plants produce the best bud color that has a better smell, density, and trichome production.

During this phase, ensure there is a temperature difference of 10°F (8°C)  between the day and night. This will ensure that you get the best quality yield.

Effects of Excess Heat in a Grow Tent

Temperatures affect how plants breathe, absorb nutrients, respire, and ultimately grow. Excess heat in a grow tent will make your plant breath quickly. As a result, it will also lose water quickly.

Plants breathe out carbon dioxide and water vapor. This means that your plants will lose much water and begin withering within no time.

Photosynthesis in plants takes place at a certain temperature. These are the level we have shared with you previously. If your ambient temperature at every growing stage is high above the desired level, photosynthesis won’t take place. This means the plant won’t produce enough food for it to grow.

Therefore, as a grower, strive at ensuring that temperatures are within the required levels.

Detecting Too High Temperature In a Grow Tent

A perfect Grow room temperature at all times should be 70-80°F (21.1-26.6°C). This is an average temperature level that can be maintained at all phases of plant growth.

As a grower, you need to be vigilant to notice when there are temperature changes.

To detect whether the temperatures are becoming too hot for your grow tent, check the following signs in your plants.

  • Fruits bort prematurely
  • Plants stop growing properly – they grow leggy and tall
  • Essential oils are lost
  • The flower doesn’t form properly

These are symptoms that the temperature is already high and is causing damages to your plants.

However, you don’t need to wait until you see defects on your plants. You can inspect and notice the temperature changes at any time over your Grow tent.

So, if you would wish to get the very best from your tent, we insist you buy a thermometer for your grow tent.

As the temperature changes at every stage, you will be able to notice them before they cause any damage to your plants.

8 Simple Cooling Solutions For Your Grow Tent

1. Ventilate Your Grow Tent

The first thing that you need to do is to ensure that there is a proper air exchange in your grow tent. You need Grow tent fans to take in cool air and remove hot air from the room.

When you think about fans, you need a fan you can regulate its speed. This will enhance efficient airflow in the Grow area. You will have just enough airflow for your Grow tent.

Titan Controls Kronus 4 is the best fan to buy for your temperature control. No matter the size of your tent, you can set it to give you adequate airflow.

2. Use an Air Conditioner

Another perfect thing to consider for your Grow Tent is an Air conditioner. It will work perfectly in hot seasons to remove excess heat from your grow tent. An effective air conditioner will supply cool air to your tent when it’s switched on.

It will help you fight all heat build-up found in your growing area.

The best air conditioner in the market is the Honeywell MO Series Compact 3-in-1 Portable Air Conditioner. You can connect it to your tent ducts and get a fresh and cool airflow in your Grow tent.

3. Use LED Lights

One of the common sources of heat in Grow tents is the lighting system. When you use lighting systems that produce more heat, they eventually affect the temperature of your Grow area.

LED lights, however, they don’t produce any significant heat.

If you want to deal with the heat coming from your lighting system, go ahead and buy LED lights. They will perform perfectly without warming your Grow tent air.

BESTVA DC Series are the best lighting systems to buy for your Grow tent. You will find them with a wattage of 1000W, 2000W and 3000W. With them, you will be assured of great performance and no heating will be experienced in your Grow tent.

4. Use Cooled Lightings

In the market, you will find water and air-cooled lightings. The water-cooled lightings are more efficient than air-cooled lightings.

Cooled lights ensure that the temperatures produced by your lighting system don’t cause heat build-up. It also eliminates the need for having conditioners in a Grow tent.

5. Run Lights During the Night

During the summer season, temperatures are too high during the day. If you run your lights, the temperatures will increase making it unbearable for your plants.

At night the temperatures drop. This is why its advisable to run the lights only at night. You won’t suffer from excess heat from the lighting system.

6. Maintain Humidity

Humidity affects the temperatures of your Grow tent. Humidity is simply water vapor in the air. Therefore, to cool your grow tent, raise humidity.

The best way to do this is to use a humidifier. You will control the level of humidity you need.

We mentioned that most of the heat you will have to deal with comes from outside. The best way to deal with it, its to prevent it from entering into your grow tent.

Therefore, in this case, we recommend that you sean your entire Grow area. Seal any part that is allowing heat to enter into your grow tent.

To do this, use a seal foam or foil. It will work perfectly.

8. Keep Your Ducting System Straight

Every bend in your ducting system will reduce airflow by 5%. This means that it will cause the temperature to build up slowly.

Therefore, to deal with this, keep the ducting system straight at all times.

Parting Shot

With increased temperatures, plants won’t perform as required. This is why it’s important to ensure that the temperatures are lowered to the optimum level.

Luckily, there are so many solutions to do this. Some are simple hacks that don’t require money. Others are effective techniques that will require you to spend some amount of money to get the best results.

The difference is brought about by the level of heat and its cause.

So, what’s next?

Evaluate your situation. Then use the most appropriate technique to lower the temperatures. But most importantly, buy the right equipment where necessary.
