I just got my 400 hps and it is pushing my grow room temps up to 100 degrees I have a 4in. inline fan ,but I am not sure how to hook it up. Would appreciate any help.
I am growing in my closet and I was thinking of cutting the hole in top of closet, but what will hold the fan in place.R u in a cabinet or closet or you have a grow closet with the vent and duct holes there already?You have a 4inch inline fan attach that with some ducting and putthe fan at the top of your grow room with one end by the bulb to suck the hot air it is giving off.
