you dont have too... The most efficient way to do it though is to get a bucket with a lid, cut a whole for a computer fan in the middle of the lid pointing up, then drill several holes around the lid for intake, obviosly as the fan is going to need to pull air from somewhere. Thats basically it. very simple and cheap.

carbon filters they fit on or can be made to fit on most exhaust lines there are many kick -ass strains out there that don't have any odor check all the strains out seed banks are a wealth of information regarding odor also "Big Book of Buds#s 1 2 &3 by E. Rosenthal has all the info one could ask for veg time,odor size,stone etc. good luck

True, such as C99. Great point, this is what stealth growers should look into and be aware of for sure.

idk what kinda grow ya have, you can easily make carbon scrubber for a duct fan. go to walmart: Get activated carbon Get big wash cloth Get duct fan, and duct Put duct together with duct fan. sew/stapple the washcloth into a pocket so it holds activated carbon duct tape several wash cloths to inside of duct... done.
