Best odor control for small cab?

Anyone want to chime in with opinions or experience on best odor control for a small cab itself located in a closet? Say something around 5 x 3 x 2 feet.

ONA?
Home made carbon scrubber?
Something else?

Ona gel. Not the block. I use it. Practically have to rub my face in my garden to smell anything

I have the block myself, does the job. Either way your good

Where do you locate the Ona Block ? In the tent/room or in the room where you exhust into ? Someone said you can place it inside of your duct?

Ona blocks do not last all that long and are not the cheapest of things. I think in the long run it would be better just to buy a carbon filter.

If you decide to go w/a home made carbon filter, here's a super cheap and easy DIY carbon filter.

I use a couple of mothballs outside the room.

Can I ask why you would say the gel over the block? I have a block and will get a few more for my first grow and was told that they are strong enough for a pc grow you can just make a hole in the top so that the ONA smell is not overpowering but still over powers the marijuana smell, and also so that they last longer. Please advise. Also with the gel, do you just leave it there like the block or do you have to rub it on your fans or something? Thanks
