i'm starting to work on planning out my grow room and know i'll be needing some carbon scrubbing for a couple of strains with some indica in them. i also have an ion generator tower that doesn't work anywhere near as well as reported back in the 80s when that was the odor control method of choice. even on full blast, you can still smell skunkier stuff, but just get a nasty metallic odor on top of it. as i'm not really growing for flavor, i thought i'd try that route for simplicy & cost. noise is a major issue with my grow and i don't want any loud whooshing fans. when i started a closet grow once a while back with just a tiny 10" box fan on low, the fucking assholes that used to live next door knew what was going on and used to slam their fucking closet doors every time i watered my plants or turn their fucking bathroom fan on & leave it howling all day while they were at work etc. i don't want to alert the replacement neighbors to my activities as they have nosy begging to be beat to death with a heavy blunt (again... no pun intended) object tendencies already too.. i also don't have an insane $200 for a box fan & motor controller. i'd like to use 4 small PC fans in DIY scrubbers in each corner of my spare room and remembering something i skimmed over a few years ago, recalled the idea of using as little as 6 volts for at least SOME PC fans to make them run at slower & quieter speeds. i worry about trying this with cheap wallwarts though because one of the grow supplies catalogues i have made a big stink (no pun intended) about using motor controllers on anything but their crazy expensive squirrel cage fans and to not use them on the still way fucking overpriced propeller style ones built like oversized PC fans. can i run a 12v PC fan with a 6v wall wart power supply without the universe imploding on itself? if not, does anyone know of an AFFORDABLE way to move air through a carbon scrubber without howling like a 747 engine? if i had the tools and some knowledge about low RPM high torque electric motors & where to get offset gears for them, i'd almost be inclined to make a coal furnace style air bellows to quietly pump air. as it stands, i'm already planning on suspending each scrubber on bungee chords to dampen direct vibrations.
