When it is time for the flowering stage, you can slightly reduce the temperature of your grow room to 70-80F (20-26c). Always remember that there should be around a 10 degree difference between night and day temps if you want to achieve the best results.
During the flowering stage of the cultivation process, you must ensure that your grow room temperature does not exceed 75°F. Temperatures exceeding this can do irreparable damage to the potency, smell and taste of your plants. If you want to guarantee that your grow reaches its full potential, keeping an eye on the temperature during flowering stage is essential.
Unlike colder temperatures, it would take a lot for a cannabis plant to die purely from an overheated grow room. However, too much warmth can have a serious impact on the length of time it takes to grow your plants.
This information can also be found in our Cold Grow Room article.
Essentially, it is all about reacting to a temperature that you believe doesn’t feel right. If you feel too cold in your grow room, your plants will likely feel too cold as well.
A overheated grow room can also lead to a number of other problems with your plants. Firstly, nutrient burn can occur through increased water transpiration at high temperatures. Mildew can also appear, especially if the room becomes too humid. Terpenes can also disappear from your plants if they are overheated, which removes those classic flavours and aromas from your strains.
If any of the problems listed below apply to what you are seeing in your grow room, it may be time to turn that heat down!
Last week, we released an article detailing what can happen in your grow room if temperatures get too cold.

During the vegetative stage of your plants growth, temperatures will need to be a little warmer than in the flowering stage. This is a key part of the cultivation process for your plants, so they need that little bit of extra heat to ensure success. A temperature of around 70-85F (20-30c) will suffice.

Now we are at the heart of the article, just what you need badly right now. Here is the list of 7 easy and effective instant solutions for high grow room temperature-
According to A Study from Sciencing , if the temperature rises in a contoured space, the relative humidity decreases. If you’re dealing with an unusually high temperature in your grow room if you find the relative humidity low as well. If it’s down to 60%(In vegetative mode), or 40%(In flowering mode), it’s urgent to increase the humidity level.
To be more certain about if the temperature is too hot for the plants or not, check for any of these bad symptoms in them-
However, it’s always better to detect a bad temperature and environment before letting your plants to wilt. A good kit can be a 3-in-1 Moisture, Light and pH meter. Here is a popular one from Healthy Wiser.
In case you don’t find any quick solution to control the temperature(living in a hot area), and still want a maximum yield, you better chill down the nutrients to a temperature of 55-65°F.
“It’s too hot inside the grow room, and the dying plants are soon going to freak me out!- What can I do now?”

Plants cool themselves by passing water through little holes on the leaves, called ‘Stomata’ . While water vaporized through Stomata, it takes heat from the leaves and cools the plants down. The process is called Transpiration.
An advice is, use a good quality humidifier, and an automatic controller to make it efficient.
Using an Oscillating Fan is the best way to get it done. Place it in a way that it can circulate air in almost every corner of the room, especially the air between the heat source and plant canopy.
