Does any one know how long a quart of Ona Gel will last me though? is there anything i can do to make it last longer? and will it completely take the odor out of the air (like even when it is budding)? thanks yall!
any one? lol.. I am thinking about running the exhuast fan out up to the attic... But i would like to make a carbon filter.. Would I be able to buy some unused carbon from a fish store and then rig up some kind of filter on the end of the ducting from the exhuast fan?
