New stealth Cabnit!

Okay, So im at work atm, so i will post pictures up tomorrow. But this is what im working with. I bought a white cabnit from wal mart, the pantry ones that are like 60$. I got a 4 inch fan hole cut on the top and the fan mounted blowing straight out through a carbon filter. The Cabnit it about 5 feet high. 2 feet deep, and 3 feet wide. I got 2 plants going. One is couple weeks old. Other is seedling. I have 8 6500K cfls about 2 inchs above the plants. What im worried about is my fan, is it gonna work with this cabnit. I have no intake holes cut becuase the doors don't seal 100% so air can be sucked in im guessing by the exhaust fan. I also have a 5 inch fan blowing onto the plants. Again ill post pictures tomorrow, but how does it sound?

sounds to me like the fan should be a tad bigger or maybe get 2 of the 4 inch fans, and u should have a fan blowing in as well as sucking air out.

Yeah i was thinking about getting another fan blowing out. But the reason id ont have a intake fan is becuase there is air leaks around the doors, So with the exhaust it should create enough pressure to suck air in through those holes.. correct?

Here are some pictures I just put a new baby in there as well. I was gone for two weeks and i got a friend to look after her and he nute burnt it hardcore. So im starting to recover and built a completely different grow box. I dont know what kinda lights he used but it didnt grow in 2 weeks at all lol... But he managed to nute burn it! Bastard.. Im going to cut a hole and put in a intake fan im pretty sure today.. but if u guys have any tips please do help

Come on ppl lol. Any comments?
