1st time grow

I am growing in my closet I have a pvc and panda film tent that is 4x2 and 4 high. 1 medical plant growing. I think it is snocap or train wreck. I am running 8 100 watt equivelent cfl and 2 150 watt cfl. The 100 puts out 1600 lumins each. I am planning on taping a carbon filter on the bottom and placing a fan for intake and the same up and across on the top for outtake with another fan. I want to get the best for what I have wich is not a lot as I have alredy wasted a lot in a futile wood box attempt. I can probally put about another 50 into it and I just started flowering last night at 9 any suggestions??? Oh yeah using miracle grow potting soil and no nutes

Might want to put your intakes on the bottom and your exhaust venting at the top instead of the other way around (if I understood your placement plan correctly) since hot air will rise and that's what you want to get rid of from the grow space.

SkunkDunks has a really good panda film tent setup you could probably get some good ideas from:
