Anyone who seriously believes it's okay to go above 85 without CO2 is simply WRONG. Sorry, there's no other way to say it.
Even you would have to admit that while it may not be ideal, growing in a high-temperature environment can be done successfully. Hell, I've got pictures if you don't believe me. Not a single hermie flower, and my plant would yield at least a couple ounces if I cut it now, at six weeks of flowering. The heat tolerance of cannabis plants isn't the same for every grow either, and depends on strain, humidity, growing medium, etc.
khronik Reviewed by khronik on . Is 85°f too hot? Near the end of 12hours of light my Hydrohut gets to about 85 degrees at its peak at the level of the soil. I use the back of my hand and it does not feel hot. I have an air cooled reflector with 80cfm pushing the heat from the lamp out the back. I have a passive intake system by using a 147cfm canfan and carbonefilter with one mini fan aiming over the top of all the plants, and one large fan at the window blowing fresh air towards the hut. THe only thing I lack is a squirrel cage fan Rating: 5
