Quick question...

I just bought a 265 cfm fan for a 4.5x4x2 room, i plan on running ducting threw my cool tube to the fan, to my carbon filter with a passive intake. I was curious, if was to hook the fan up to a temp controller, when the fan was off, would i have to worry about smell escaping my room? (Provided everything else is sealed)

Thanks...

depends how many plants you had going in there, but if you can seal up the room fairly well the smell should stay put for the most part, just don't open the door untill the lights are on and fan has ran for a min to clear the stale air.

Looking at maybe 20 plants... sog style, aero garden. IDK tho, we'll see...

20 plants in the ag?, im confused, but you should pre plan how many plants and how your going to fit them, you can cram them pretty close sog style but they do need enough room so they won't overcrowd each other.

not an aero garden, but an aeroponic garden. Im doing like a hybrid aeroponic/nft system. Looking to do 4 rows of 5...

ahh ok, sounds good then. i thought maybe you were thinking of setting up a bunch of aero's, cause then i'd have to start talking down about the idea. sorry.
