Can you not run something like an 8/10" fan running a 3 way split to each room n have a 5 or 6" filter in each room attached to the ducting?
this is what ive got
1x6" aircooled hood
1x5" aircooled hood
1x5" cooltube
1x 700m3/ph 6" extractor
1x5" rvk
1x5" tt inline adjustable
1xfan controller
2xnew 5" carbon filters
2 tents
1 with 400mh in airoocled 5" hood
1 tent with 1200 1x6" hood and1x5" tube
right
thers a 6" outlet on the roof im using as a inlet for the veg
i have 3x outlets for the home system, 1 to teh kicthen and 1 to teh bathroom upstairs and 1 to the bog downstairs, the bathroom upstairs is locked and rarely gets used, im changing that to a 6" outlet for the flower as its only 4" the resti cannot change as ther downstairs and ther built into the wal cavaties
so im thinking duct from teh outlet on the roof thru both tents and thru all 3 hoods and then into the 6" outlet in the bathroom,
then
use the rvk on the veg filter and duct to the kitchen as it is now and the TT to the flower filter to the downstairs loo both are on controllers
THEN
on teh roof vent stick a flange and split to 2x 4" and run to ech tent as a fresh air inlet
???
i have more equipment a big black extractor and another 400 ballast BUT ther in use for another few weeks
