cannabis growth slows at high temps.
Good temps are 72-77 day time
58-64 night time.
Too hot causes many problem with pests, and you will also probably need to feed them more often. 100 is NOT good under any circumstance.

best of luck,

daima Reviewed by daima on . 100 Degrees Is 100 degrees F a deadly temperature or is it something that is ok? I know tomatoes thrive under average of 83, but my grow room as is gets from 86-100 depending on how I have stuff set. To make it stay around 86 I have to keep my window open at night, and leave my closet door open. I would do that but the bright HPS gets a tinsy bit annoying. Thanks for any info in advance. Rating: 5
