Increased stretching

Do marijuana plants cease rising at sure temperatures?

The excellent news is marijuana plants don’t cease creating when there’s an excessive amount of heat. However, their development will decelerate.

For the sugars to be distributed all through the plant, the plant temperature must be above 20ºC or 60ºF. Within the case of sugars, heat is an efficient factor. If the plant isn’t heat sufficient, the sugars might be caught, and the plant will endure. Once the plant is heat sufficient, the sugars will probably be distributed to their respective locations.
