Hey I like that idea of using duct to create a connection between the grow room and the attic but Im afraid of mold since I assume the attic will have quite a bit of humidity. Im deathly afraid of getting mold because It ruined my first crop and my second crop only got a tiny tiny bit of mold and everytime I smoke it makes me sneeze.
if u ever make your own strain call it the amish fucker
this is a idea i came up with for myself ..........u can just get the lvl 10 filter
1 home depot filter 12x12x1 lvl 9 ........
lvl 10 should clear everything it is like hospital lvl filtering (cost 20 bucks)
2 a large flat ratebox from the USPS (free) 12x12x7or 5 ......it is in the box by the door saids free normally at the bottom
3 a can of spray rubber (home depot ) look by the spray paint cans several kinds just need to be rubber sealing 7-12 bucks
4 roll of duct tape 4 bucks
5 a booster fan (
6 inch one off amazon 240 cfm has metal blades) 35 bucks
6 flexie ducting how ever long u need plus connetors ( u might want insulted for less heat lost)
ok once u decide on the ducting size and get the booster fan
make the box and seal on side with tape (take the booster fan and press into the bottom making a circle) use a sharp blade and poke/cut out
now take it outside and spray it down inside/on the coners outside and the hole ...........i did mine 2 times hung it for 6 hours let it dry do again wait untill morning
now cut off the extra flaps and tape in the filter (u want to have the hole in back open to help this ) ..............once that is done u can put in the ducting(the ducting will go in with some work and once u open it up u can tape it down) or the fan now ( if it is the fan u tape it on good to the box)............then run it to the tent ........it is a long way with alot of bends u will need several boosters
