Ventilation and Exhaust

Okay, so my question is about where to send my exhaust air. I was thinking about drilling a hole in the ceiling drywall and exhausting the air in between the two floors. Would this be enough space for exhaust. There is 12 feet til the outer wall and about 2 feet in between each of the floor joists. I know its not alot of room but I nots exactly air tight between each joist eithe. Well everyone tell me what you think.

It will work if the air is filtered.

its not exactly air tight between each joist, but it wont give you much flow either. how big is your room? it might work for a small closet but better ways exist for anything larger. getting it up high (2nd story or better)is good to keep odors unnoticed by neighbors. a carbon scrubber works good.
I have vented into another unused room and run an ozone generator in it(the unused room), then vented that room out a clothes dryer vent to outside.

The room is 5' x 3' x 8'... By the way.

unless ur just growin a 2 or 3, that used air should be sent outside or ur gonna have mold n mildew problem in the future, depending on how many ur growing. cut a 4" hole thru the wall to the outside, just above the foundation if in a basement, right in the middle of the wood plank. put a carbon filter on the exhaust, odur socks r useless. U'll be sorry if u keep that stale air inside, even if there's no smell

what if you were to send it to an atic? i have 3 feet of blown insulation in my atic and was wondering if it would be bad to run a duct up there

well how bout running 4" ducting in ur atic from inlet to outlet? so u never actually release any stale air into the atic; cut a 4" hole in the roof, $35 for the 4" hole saw bit 4 ur drill, real easy, get a roof hood, 40 bucks, some hoods say use 4.25" hole so be careful. that is unless ur not too concerned about mold...

cut the hole from the inside out, right thru the shingles if u can, or just through the wood, then cut the shingles n shit with a utility knive so u have ur 4" hole. then get on the roof and slide ur ducting on the backside of the roof hood through the hole, silicon around the hood with the most weather-resistant shit u can find. then a back-draft dampner on the inside after the hood vent, unless the roof hood already has one inside. then ur ducting... seal around the inside with silicon too. there will be instructions on the roof hood for hole size and insallation. ask the ppl at the store where u get the hood for any tips on installation

I think you need to work out man, you look a little frail and pale.

Lol I know man all this stressin about ventilation is killing the physique... not mention the damn tan.

So this is my logic... I'll exhaust it in between the floors and it will disperse throughout the house. There are holes drilled for wiring between the joists and its not air tight so I figure the air has to go somewhere. As long as the exhaust air is not coming back into the grow closet then no problem right????

I think I'm going to test it out, unless anyone has anything to point out that I may have missed, If it doesn't work I will put a vent in the ceiling of the adjacent room, directly between the same joists I am venting between.

Thanks for the great input everyone!

Don't exhaust between your floor joist vent it to your exterior wall or at least into another room I have been in the home building business for 30 years I know I am old.

most attics have some wall space or eaves,you could pipe up to attic and vent out the wall/eave. homedepot has bath fan vent kits
