Cannabis and Heat Stress: How to Recognize and Solve It?
Although most cannabis varieties tolerate heat well, heat stress can occur during cultivation. Cannabis plants can only withstand a certain amount of heat and light. Intense heat can be a serious problem that can permanently damage or even kill the cannabis plant. Even varieties that seemingly survive heat stress may ultimately produce lower yields and poor buds. 
What is Heat Stress in Cannabis?
Heat stress means that cannabis plants lose their ability to self-regulate internal balance, which helps them cool down. Cannabis likes high temperatures, but sometimes it can be too much, which can cause a number of problems that can seriously affect cannabis if not addressed in time.
Heat stress in cannabis occurs when plants are exposed to higher or lower intense temperatures than they can tolerate.
Why Do Cannabis Plants Overheat?
Overheating does not occur just because it's hot, but several other factors need to be considered to help you better recognize and find its cause. There are several reasons that cause heat stress:
Too Much Light
Intense lights are often the cause of excessive heat. For this reason, LED diodes are generally preferred over HID lights, because they produce less heat and can be easily dimmed.
Low Air Humidity
If you grow in a very dry place, plants quickly lose moisture. Low air humidity prevents plants from cooling down.
Insufficient Ventilation
Ventilation is very important for cultivation. Plants without enough fresh air are prone to overheating. Ventilation helps maintain low temperatures.
