CFM backpressure

YASoob ,
hey been a min. sorry for slow reply .
i started w/ only 1-1000w. n expanded later . thus the 2- 6in. vortex fans verses the 1-8in. / as far as your filter , 6in. vortex will be fine .

i have a couple sharp turns in my duct work . i have no light leaks w/ galvanized ductwork and it doesn't obstruct flow like the accordian foil type duct.

also doco is right , plan 1= bad cause you'll be pulling carbon dust through your lights n gettin em all dirty .

i'd go w/ the 8in. on lights -n- 6 in. on filter .
my rooms not to loud w/ 3 blowers going , but i have a fan speed controller on the 2-6in. blowers -n- my stuffs in my basement anyways .
peace
crispi :thumbsup:

My setup is somewhat different than yours so my methods may not apply. I use a Hydro Hut so essentially I have a grow room within a room and I am able to keep the cool tube sealed off completely from the grow area - air comes into the tube from outside the hut, through the tube and is expelled outside the hut though a window - that way the only odor I have to control is from within the grow area which is where my carbon scrubber is attached to the squirrel cage to exhaust, circulate, & scrub the grow room air. Intake is passive through vent flaps.

Your closet area has different requirements and the fact that you don't want to do any hole cutting has its on limitations. Is the closet completely sealed from the other areas? You may end up using your original idea and it might be perfect for your setup! Keep us up to date so we can all benefit from your experience.

thanks you for the advice. good to have some inspiration. I didn't want to use my dayton to suck air in. Its not effective as the can fan. What did u do to block the other side of the dayton doco?

[YASoob]

i mean i didn't want my dayton to pull air from the carbon filter

Sorry if this is hijacking but I'm contemplating a vortex w/speed control and carbon.

Could you push air across cool tube, then into carbon scrubber?

Basically, outside air > vortex > cool tube > carbon?

I'm looking for a 1 fan solution if possible. Only running 400w in a fairly good sized room. Runs of duct would not be more than a few feet each. Thanks for any input.

I just realised what I posted wont make sense without more info. I wont be scrubbing the outside air, lol. I'll pull air from in the room itself, and passively through open doors from outside.

It stays around 79 degrees right now with just an old table fan. My concern is some cooling, but mainly odor control for the massive stinky buddlies to come.

hey mister e ,
my carbon scrubber works much better if air is drawn thru it . not blown into it and pressurizing it . i've tried both ways .

the only way i see you getting away w/ only i blower is outside air in >thru cooltube >into a duct that resembles a y w/ filter on 1 leg , and like an 8in vortex or huffican drawing air thru both the tube and the filter and exhausting into the room like you were doing anyways .

Hmm cool, that sounds like a decent option. Thanks, xcrispi.
