Ona gel?

does this stuff work? and would it be better to put inside a grow box or outside?

outside the grow room, and yes, the stuff works like a charm, find Roseman's recipe for his ona-gel bucket, great idea and it's supposed to cover the whole house with 1 5g bucket..

i askd a worker at a hydro store and they told me that it only masks the smell

ok but if i had exaust coming out of my closet into my room, the smell would come in my room. wud it cover that?

there are tons of super cheap DIY carbon filters on this site. use the search. ona masks the smell with a super potent chemically smell. and once the top layer starts to harden you have to keep stirring it to keep the ona smell going.

ONA gel was composed for sewage plants and other disgusting sites! it bonds to the smell on the chemical level and makes it smell nice! and yes it works!!! carbon filters are bad ass but not discreet!

You can get ONA BLOCK, it's in solid form and comes in a smaller container than the gel, just drill a few holes in the lid or take it off completely and stick the container in your exhaust ducting! costs about 10 bucks, lasts a month or two and is effective for small micro-grows!
