Okay so I am pretty new to this forum but I have been looking at other peoples posts for a few years. I finally decided to register and see if someone could help me with my questions.
My question is, I have a 3x3x6 wooden box I am growing in. I want to know what cfm duct fan I should buy and do I need to pull the air from outside the box to cool the lamp or can I just pull the air from inside the box through the cool tube? I will also have 2 small fans running inside the box. My light is a 400watt MH. Thanks for any help ++rep
