I cant stress enough THE IMPORTANCE OF CARBON FILTERS for neutralizing odor.
A friend of mine is currently growing 6 plants, White Russian strain, and they are 3 weeks old.
they havent even sexed yet, and they fucking reek of weed.
that earthy, musky, dank, greeeeeeeeeen smell of ganja.
OUTSIDE the growroom you cant smell shit, but step inside that place and the smell of ganj smacks you upside
the head....
Dont skimp on carbon filters. They will pay for themselves AND cover your ass in the long run.
peace,
