ok so the tent is 55 x 55 x 79 has 3 Itegrated Vent Flaps witch ill keep open wont let light in at all.. just allow air flow from outside in. HTG Supply - Grow Tent | Silver Lined Grow Tent | Agromax Grow Tent Now im going to grow 9 plants DWC in 5 gallon buckets. should i run 600 HPS or 1000 HPS also how much other venting will i need? HTG Supply - 8" Inline Duct Fan Could get 2 of those and have 1 Blow In and 1 blow out? i dunno to much about venting so really could us any advice on this ! Are they to cheap will they suck? also what hood would be better http://www.htgsupply.com/Product-Euro-Reflector.asp or http://www.htgsupply.com/Product-CoolTube-6in-Reflector.asp
1000w MH/HPS with air cooled reflector, 6 inch exhaust fan will be fine, no need for intake fan. edit: not the fan like you were looking at there, get one of the vortex or centrifugal fans or whatever.
here's how i have mine set-up....hope it helps...i find running the filter outside the tent works best for several reasons...
thats an interesting way to do it buddogmutt, I have my air filter>hood>fan>outside, thats the way the guy at the grow store suggested me to do it.
