What is the best temperature for flowering lights ...

In the beginning of bloom your humidity can range from 45-50% you should lower it to 35% in the last few weeks of bloom. Ideal temperature would be 75 F but anything in the 68- 80 F would work. A 10-15 degree day night temp swing is also acceptable. If temperatures are too hot or cold it will slow down bud growth If temps are too high it can effect the smell,density and thc content of the buds. Hope this helps good luck
