Temperature Debate....

Well, i was just wondering what the best temperature is for cannabis..On average that is..I know the strain of cannabis plays the biggest role in tolerance to high or low temps.

A buddy of mine grows indoors in his closet. He likes to keep his temperature around 85-90F. Plus he really doesnt have a choice because of poor ventilation. But his plants always do pretty damn good..

The strain im growing was found growing in hawaii, so i asume it can handle high temperatures and a good deal of humidity..I dont know how i can keep it humid, but keepin it warm isnt a problem...

Any ideas or info yall wanna share from experience with temps?

From what I have read, but dont know from experience, the plants can thrive in higher temperatures if the CO2 levels are adequately high. So if nothing else the plants have the capabilities of surviving those temps, dont know much about it past that.
