oceangrown Reviewed by oceangrown on . New products and STORE reviews!!! couple things i ran into at the hydro store i go to. htgsupply dot com they have a store in shrewsbury mass right off 146. but the manager gave me some "ONA block" its a odor control $6 . i placed in my 2' X 4' X 7' tent and took away all the odor and i didnt even take the cap off or poke holes in the top cap like directed.....i simply unloosened the cap slightly. works great no need for carbon filter i did some googling and found great reviews as well so i figure i share. Also, the manager Rating: 5
