Venting grow room

Hellow i have a 8x8x4 grow tent i currently just have one fan in it and th door open to blow air out and this worked fine for this round (HARVEST DONE) I HAVE THE DUEL SIX HUNDRED WATT BALLAST SO (TWO SIX HUNDRED LIGHTS IN IT) BUT THIS TIME IM PLANING ON PUTTING A EXTRA THOUSAND WATT LIGHT AND WANT TO INCLOSE IT (DOOR FLAP NOT OPEN) I WANT TO VENT IT WITH A FAN TO A CARBON FILTER CAUSE THE SMELL IS TO MUCH> MY QUESTON IS FOR THIS SIZE TENT WITH LIGHT AND HEAT WILL ONE VENTING FAN WORK? IF SO WHICH ONE WOULD WORK THE BES? IF THATS NOT ENOUGH WHAT SHOULD I DO?

PS MY SHIFT BUTTON GOT STUCK> DOT DOT DOT

shift button fixed!ZOH I SHOULDNT HAVE MADE THE !

get sealed/vented hoods you will need at least 500 cfm fan to vent the space, and another fan to vent the hoods outside the tent around 250cfm to vent the lights

W'sup go-big.. ya gotta have vented lights cause' your gonna need to get all that heat out... your best bet if you wanted to only use one fan would be this:

-You would need a 465 cfm fan either a boxy squirrel fan or a BLower (either one is about a hundred bucks at a grow store) and ducting

what you wanna do is hang the Carbon filter with chains (horizontally) at the very top of the tent cause heat always rises to the top of any enclosure.. preferably hung above the lights..

Hook the inlet of the blower up to the opening of the filter so that it's sucking in air from inside the filter..

hook the outlet of the blower to a duct on the first light..

Then connect ducting from the first light to the second light, and also ducting from the second light to the third light..

When all the lights are connected, hook ducting connecting the last light to a vent leading to out side the tent..

Lastly open up a hole at the very bottom of the tent and leave it open

--- With the blower on pushing air through the lights and out of the room it'll decrease pressure inside the tent (a lot).. by leaving a hole at the bottom of the tent, the decreased pressure will naturally pull in fresh air from outside the tent (and colder air since it's at the bottom)..
-- Just make sure that the blower is ALWAYS on or air will be able to leak out of that hole..

Hope I helped man, happy growin and better smokin

WEell i have a 8inch vortex powerfan, the 2 600 watters are in hoods that have the side whoels to put ventalation to but no glass screen on them. The 1000watter would be in a lumewing hood

possible to vent the hoods with out the glass cover?
