not even a small hole for a PC fan?

i use 2x150watt hps and a PC fan was able to cool one of them, with both i needed more air going out.

90F is too hot, is there any incoming air?
invision Reviewed by invision on . First grow - 150w hps Hey everyone. Long time watcher, first time do-er here. I have 4 plants going on which i grew from seed. Its been about 9 days since they sprouted.. For the first week, it was under a 22w 6500k flouresent lamp. I dont know how that affected it...but i dont think it was good, because it hasnt really done much since i put it under the hps. Here are some pics! Rating: 5
