It seems you're on a really low budget on this grow. NO worries about that i'm on a less than 50 dollar budget on my grow and it's doing fine with floros. It seriously cant be that expensive to buy a little fan to use i mean a power supply fan isn't gonna push hardly any hair at all and probably make almost no difference. You dont have to have a huge fan but i'm sure u can find some little 5 dollar fan or something at dollar general or something of that nature.:rastabanna:
