hey guys im building a grow box 2x2x4 feet and i already have a cool tube (pyrex bake around) for my 400w hps my questions are:
1: will a 160 cfm inline fan be enough to cool the grow box and the cool tube.
I will be running a 1 ft duct from the top of the grow box to one side of the cool tube which will be the intake.Then on the other side of the cooltube i will have the inline fan pulling air out from the box over the bulb and outside. will that be enough cfm to cool both?
2. I can only access my plant at random times and i do not want to interrupt the night cycle. i have heard of a "Green" bulb that does not affect the cycle where can i get this bulb from?
