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.
