Grow Room Temperature Too High- Cooling Solutions

Grow Room Temperature Too High- Cooling Solutions

Every condition in your grow room should be kept at an ideal level. Maintaining a proper temperature is a common issue that a grower needs to manage. 

The appliances in the grow room also generate some heat, and you will get excess temperatures from the outdoors. It will make the temperatures of your Grow tent intolerable. 

Also, that is the reason you need to cool the space off. 

In this article, we will discuss how you can cool down your grow room.

However, before we do that, we will first examine a couple of things you need to consider when it comes to high temperatures in a Grow tent.

The ambient temperature is the temperature that is favourable for your plants to grow well in a Grow room or tent. It is influenced by the temperatures inside and outside the Grow room or tent. 

The ideal temperature should not go low or high. If so, it will end up affecting your plants. 

As a grower, you need to make sure that the temperatures are maintained at a favourable one consistently. It will assist your plants with breathing and suitably at each stage.

It would be best if you also made sure that the temperatures are maintained at a specific level at various stages. In each step, guarantee the temperatures are within the designated limit. 

The temperature level in the germination may be fatal to plants during the vegetative stage. This is why you should always be attentive and guarantee you maintain the proper temperatures constantly in the grow room or tent.

How Does High Temperature Affect Your Plants?

Temperatures do influence a plant’s capacity to photosynthesize, seed germination and natural flower or fruit development. It helps in preventing poor yield.

Here are a few basics to consider when it comes to high temperatures in your grow room or tent:

First things first grow lights are radiators. LED, HPS, Fluorescent, Plasma, and whatever else we can name all grow lights emit heat. Also, when you are leaving the grow room with all lights turned on, you are pretty much letting the lights heat the grow room.

A high temperature of a grow room directly influences the leaves and the roots of the plants.

Here is how it works:

Plants cool themselves by passing the water through tiny openings on the leaves, called ‘Stomata’. While water is vaporized through Stomata, it takes heat from the leaves and cools the plants off. This process is called Transpiration. 

Hot temperatures and conditions enact the guard cells around Stomata while water is passing through it. Furthermore, that also causes pressure on the root system of the plant. 

It ends up shitting your plants down with no photosynthesis. Frankly, it means the death of your plants.

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

An ideal grow room needs to have 70-80°F (21.1-26.6°C) of stable temperature. What we mean by ‘stable’ is that it needs to be something very similar throughout the whole contour. As the temperature around the sources (lights) are higher, you can use oscillating fans to move the air around. 

Notwithstanding, that is the generalized temperature range for quickly growing yields. However, a bit of a hike in the temperature is acceptable, only if you have a water cooler or something to guard your plants’ roots.

To be super sure if the temperature is super hot for the plants or not, check for any of these signs in them-

  • Plants stop growing or grow tall and leggy.
  • Flowers do not bloom as expected.
  • The essential oils are lost.
  • Fruits become rotten prematurely.

Notwithstanding, it is always a great idea to detect a lousy temperature and environment before letting your plants to shrivel. A good unit can be a 3-in-1 Moisture, Light and pH meter.

Temperature Requirements At Different Growing Stages:

As a grower, you need to guarantee that the temperatures are maintained at their ideal levels. This will help your plants with breathing and thriving correctly at each stage. 

It would be best if you also made sure that the temperatures are maintained at a specific level at different growing stages. In each step, guarantee the temperatures are within their limit.

The temperature level in the germination stage may be harmful to plants during the vegetative stage. It is why you should always be attentive and ensure that you maintain the correct temperature in your grow room or grow tent all the time.

Seedlings Phase 75-95°F (21-33°C) 

Germination and seedling stages require a higher temperature than any other growth stage. At this stage, your plants are growing at a high rate; therefore, the heat requirement is also high.

In any case, to get the best out of this stage, the temperatures must not go beyond 95°F. In case it does, the seedlings will start shrivelling. 

At this stage, the seedlings are weak, and any temperature changes will cause a tremendous harm to the plant. In this way, if you wish to get the best out of your plant, ensure the temperatures are maintained within the ideal levels.

Vegetative Phase – 70-85°F (20-30°C) 

The vegetative stage is a phase at which the plant is growing. The leaves are blooming, and branches are forming. This stage is distinguished by continued growth. 

During the vegetative stage, your plants would require more heat. Fundamentally, you should keep the temperatures between 20 degrees Celsius and 30 degrees Celsius.

Flowering Phase – 65-80°F (18-26°C) 

At the blooming stage, your plant begins creating buds and giving yields. At the point when your plants hit this stage, it is great to bring down the temperatures in the Grow tent. 

Lower temperatures help the plants with creating a deep bud colour that has a superior smell, weight, and trichome production. 

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

Grow Room Temperature Too High: Cooling Solutions

Now that we are at the core of the article, here is what you need to understand at this moment. Here is a rundown of some simple and foolproof ways to control the high temperature of your grow room:

Method 1: Ventilate Your Grow Tent

The main thing that you need to do is to ensure that there is a proper ventilation in your grow room or tent. You must get your hands on a grow room or grow tent fan to take in cool air and remove hot air from the area. 

At the point when you consider getting a grow room fan, you need a fan whose speed you can manage. This will upgrade the effective wind stream in the Grow area. You will have an ample amount of airflow in your grow room or grow tent.

Method 2: Have A Low-Strength Nutrient Solution 

A hot temperature actuates more water through the leaves, bringing about a higher consumption of water from the roots. It constrains them to intake more supplements.

Also, a higher consumption of supplements comes with a risk of damage due to the toxicity of these plants. It, in the long run, causes death. 

Therefore, to avoid this situation, dilute the supplement solution to a certain percentage (people prefer using 20 per cent). Adding the right amount of distilled water is all you need to do. To keep the solution consumable, keep it very well-agitated by adding an air pump and some air stones in it.

Method 3: Use an Air Conditioner

Another method you can take into consideration for your Grow Room or Tent is an Air conditioner. It will work like a wonder in hot seasons to remove the excess heat from your grow tent. A good air conditioner will supply cool air to your tent when it is turned on. 

It will help you with battling all the heat buildup in your growing area.

Method 4: ​​Improve Air Flow 

Air is the channel that conducts heat from the heat sources to the plants. Thus, if there is a way to ensure a potent air circulation within the growing area, heat will reduce the impact.

Using an Oscillating Fan is the most effective approach to make it happen. Please place it in a way that it can course air in pretty much every corner of the room, particularly the air between the heat source and plant canopy.

Method 5: Enhance Humidity 

Humidity is the glaring thing that comes after the temperature in any conversation. Humidity and temperature are directly related. A grower can control the grow room or tent’s increased temperature by getting the hang of the relative humidity.

If the temperature increases in an enclosed space, the overall humidity reduces. In case you are dealing with a surprisingly high temperature in your grow room and if you track down the relative humidity is low as well, take charge to increase the moisture.

If the relative humidity is down to 60 per cent in the vegetative stage or 40 per cent low in the flowering stage, immediate actions should be taken.

While you increase the relative humidity level to save the plants from drying, you must also keep in mind that it will end up cooling down your plants. Therefore, get your hands on a good humidifier and an automatic controller to make sure that your plants are sound and secure.

Method 6: Cool Down The Nutrients

If you think that your plants can withstand a high temperature, you are off-base. Pretty much any grow room plant can withstand 90-100°F and an even higher temperature. 

In case you do not track down any quick solution to control the temperature and still want a good yield, you better cool down the nutrients and vitamins to a temperature of 55-65°F. 

If you think that your plants can withstand a high temperature, you are off-base. Pretty much any grow room plant can withstand 90-100°F and an even higher temperature. 

In case you do not track down any quick solution to control the temperature and still want a good yield, you better cool down the nutrients and vitamins to a temperature of 55-65°F. 

To ensure that the temperature of nutrients and vitamins do not get high, you must use a pump that circulates the supplement solution. An aquarium chiller is the best device in this situation.

Method 7: Use Cooled Lightings

On the Internet, you might come across water and air-cooled lightings. The water-cooled lightings are more effective than air-cooled lightings. 

Cooled lights ensure that the temperatures produced by your lighting system do not cause heat buildup. It also eradicates the necessity of having air conditioners in a Grow room or tent.

Method 8: Run Lights During the Night 

Throughout the summer season, temperatures are excessively high during the day. In case you run your lights, and the temperatures will increase in the growing area, which is unbearable for your plants. 

Around evening time, the temperatures drop. It is the reason why it is crucial to run the lights around evening time. Your plants will not suffer from the excess heat buildup.

Method 9: Seal Your Grow Space 

As a lot of you might know by now, the maximum heat your grow room experiences comes from the outdoors. The most appropriate way to manage it is to keep it from going into your grow tent. 

Hence, for this scenario, we suggest that you seal your entire grow area. Seal any part that is letting heat to go into your grow area. 

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

Method 10: Keep Your Ducting System Straight 

Each bend in your ducting system will reduce the airflow by 5 per cent. That implies that it will make the temperature to rise gradually. 

Therefore, to keep this in control, hold the ducting system straight.

With risen temperatures, plants will not grow as expected. This is the reason why you must ensure that the temperatures are brought down to the required level. 

Fortunately, there are plenty of solutions for you to sort this. Some are essential hacks that do not require you to spend even a single penny. However, for some, you might want to invest some.

That being said, we hope this article does wonders for you and helps you in cooling down the grow room.
