Hello everyone. I just have a couple of questions on my grow room. My room is 7' by 8' by 8.5' high. my questions are venting. what type of venting do I need? im a real handy man so I can rig up anything just about . so I would need a vent for air in and air out? would 6" be an ok size? what about temperatures... whats the ideal temps, from what I read its about 75f to 80f... also on the size of my room I was thinking about 2 1000w grow lights.. will this be enough? or will a third or even forth have to be installed. another question. Mylar will it help my babies with the light and temps? . That's all for now any comments would be much appreciated.
