How do growers manage to keep the room hot and cool ?

If they have a outside fresh air supply, how do they manage
to keep heat inside any different from outside?


2 bonus questions: is it true that if a female marijuana
plant is grown in vegetative stage with out a male plant it will die ?
And how long does it take before they can tell if it is a female or male?

you really need to read a bit???

we control temp in whatever way we can

No

5 days to 3 weeks depending

No offense to you, but these kinds of questions reveal just how little people actually know about the drug they demonize.

Heat is generally the enemy of weed, at least indoors it is. Without enough water, it's true for outside too.

I would stop speaking to the knucklehead that put that last thought into your head, the one about the plant dying without a male. If you ever start growing, sell this person all your males.

Great answer!!!
