i do not know what to do with ventilation. i got a room 12'x6'. i got 2 fans. what do i do with venting? i want it to get rid of all smell and not sound too loud in there.
how many plants? as for smell u can use a carbon filter for a big grow, or some sort of air freshiner or nuteralizer, & u can use a bathroom vent fan or a squarl cage fan to vent hot air into the attic, or if u can to a duck to the outside from attic
