Odor question I CANT find an answer to

rrrrrrrrrrrrr

Nope, the air has to pass through the carbon for it to eliminate the odors, sorry! Try ONA gel for a small area, but in flower it'll still be hard to cover up that smell.

Yep what Metasynth said, you will have to have a fan to pull air through the shoe box, and ONA gel would work for a little bit,
your best would be just to buy a carbon filter and fan combo, I paid 120 for 170 cfm fan and filter, fan works great havent used the filter yet.

I see, what about taking an aluminum container with air tight hood, cutting one side and placing a fan right on top of it, then putting the activated carbon inside on the other end?

The fan would have to be strong enough to pass the air through the whole container to filter the air.

You do know a grow needs ventilation, right?

Yikes, well, I don't really know. Try ONA gel, and get one of those Air Fresheners they sell that automatically spray every 20 minutes.

Carbon filter all the way. I've seen quite a few DIY for making filters, i can't attest to how well they work but none of them come close to the 10-20 pounds of activated charcoal you can get with a "real" carbon filter. I guess it depends on the # of plants and how stinky they are.

FYI you don't have to actually vent the air anywhere, you can just filter it back into you grow room...and keep refiltering it really.

Ona works way better than a regular air freshener but it still tends to smell like ona and weed.
