How are you installing that fan and charcoal filter together again?

BTW I have a 1280 blower to cool my lights right now and it works great. I built an air box so I can run multiple single outputs to each light and still have plenty of air.

You can build one out of a rubbermaid tub 10 gallon size and some tin collars. You need to seal the whole thing tight and use 1/4 bolts to hold the top on and door stop seal to seal the lid closed. It's not hard at all but it gives you plenty of air and a good delivery system you can add to later if you need to.

Just something to think about.
Zandor Reviewed by Zandor on . Fans, Fans, Fans I'm about to get my new grow room cranked up, but I was just wondering what others might think of my fan situation. I'm using a 365CFM fan to circulate air through a charcoal filter for room ventilation . I have a 635CFM fan for 2 600W HID's, but not sure if that's gonna' be quite enough. Anyway, my cousin works for a wholesaler and was able to get me a Fantec 980CFM fan really cheap, so I picked up on it; would it be better to use the Fantec to cool the HID's and just use an electronic speed Rating: 5
