hi im working on keeping my grow temp at a good level and was woundering what a good temp to keep the room.

depends..if ur using coc anywehere from 85-91f..if not,keep at 75-85..rember cannabis is a tropical plant,and likes a warmer enviromnet than a TOO cold envornment.....just not above 92f as this is too hot for confort......always have a fan blowing up at the bulb to further cool the room by 5-10degrees....aiit nigga

but i heard that the heat above 85 can make my plant hermie

hell na...not necessraly but yes high heat WILL stress your plant..and strssed plants=hermies
thats what i told u nigga!!! 75-85....
