Oh sorry. I'm using a 400 watt MH/HPS system. Temps get about 95 with it on and a lil circulating fan. So I'm guessing I need a good fan. I want one that will get my temps down to 75-85. I want a powered inline fan.
you have 160 sqr ft of air to remove so any fan rated over 80cfm should work. Also, get a fan blowing directly on your light to keep your heat down.
Okay, thanks. My current grow is in a bathroom with a window fan blowing in cool air. But after this I want to grow in my closet and get a nice 8 inch inline fan (520 CFM). Hopefully it will do it's job.
I would go with the Vortex Power fans best on the market. I rememebr someone saying its best to to be over prepared with your ventilation or sumthing like that www.cheaphydroponics.com has the chepest got my 6in(449cm) for only 165. "now thats a fuckin deal"
