thanks for the post bobbong. do you know if the candle idea actually neutralizes the smell when it burns oxygen? (and inreturn i know it lets off CO2) and i assume the incense just 'covers' and 'masks' the smell right? i have a 3ft right now and i think it will produce good stuff, just maybe alot with alot of odor.any other ideas? i have ionizers, ona blocks, candles, incense. not rich enough to go for carbon filters. though one day i will.
