Hey there guys! I've done a lot of thread searching and research and i think i've about got a setup in mind. I want to have everything planned well ahead though for a smooth grow! So far i've got a 35"x22"deepx50"high cab in the building...I've got 3 CPU fans pumping 118 CFM each at the top back of the cab out a window, and 2 CPU fans at 118 CFM also at the bottom for intake. Will this be enough ventilation for the area? I used a calculator i found on a grow journal here and found one would be enough but that seemed a bit off to me For seeding/veg i was planning on using just basic 8-42w CFLs, the 150w equivalents.. I saw TripStick had pretty damn good grow using them on his journal http://forum.grasscity.com/indoor-grow-journals/407430-new-medical-cab-bag-seed-125w-cfl.html Would 8 of these seed/veg 3 baby girls? And i plan on moving up to a 150 HPS as Trip did but would enough CFLs do the trick also? Im on a pretty tight budget. Also, i found a few things about it but wasnt able to get a true answer... has anyone had success putting carbon filters over CPU fans? Im gonna get back to working on my cab in the meantime! Any tips/help would be awesome!
