k, so i got all the necessary supplies... even this thing, it wasnt expensive but hard to find (and maybe a little expensive) so... what do i do with this thing?
i never tried one for a grow but i now that they are used in bigger air conditions to kill airborne bacteria, same reason why O3 is used in modern water treatment plants to clean tab water of bacteria and tapering the need for high doses of chlorine in the water which isn't to healthy and a big trouble in waste water treatment... smell is rather reduced with carbon filters in those systems
i personally go with a active carbon filter, homemade one and that does the job damn well, the only thing i had to buy for that was the active carbon which is cheap to buy. the rest is chicken wire, plywood, battens and some old cotton t-shirt without holes. so stuff most have sitting around a grow anyway.
