I went ghetto my first grow, this time around got everything setup as I like to think of it as almost professional. Have a look: I have a 4" Inline fan blowing air through the left side @170cfm, and then a 273cfm Exhaust fan coming out the top. Am using a 400 watt MH w/Euro reflector from HTG. Plants at the moment are two bagseed from a nice heavy Indica, and also an LA Woman. Next grow will include some New York Power Diesel that I got from Attitude. Throw down some comments guys!
