i have seen that air filters/scrubbers for reducing odor can be kinda pricey. i am cheap and dont want to spend $75-100 on a filter.
if all there is inside them is activated charcoal, i am thinking i can whip up my own odor control device for half the cost of buying one ready to use.
has anyone made their own air filter? and if so, how did you go about it and what was the total cost?
alternately, i have thought about just having the exhaust fan duct blowing directly out the window- and not using any odor control at all… i live in the country, nearest next door neighbor’s house is maybe 100 feet away. just how smelly are these plants supposed to get, and for how long?
i will be growing blueberry, northern lights, and amnesia haze, all autoflowering strains, and all 3 simultaneously.
TIA for answers
