Ok so my last grow was nebulaxstrawberry/kush and it was the stinkiest grow ever. I contained the smell a little with a fan/carbon combo it worked well. Well this new grow is a bagseed strain that myself and a friend have refined and it absolutely reeks of asshole and elbows and musk, even in veg it did but now its horrible. its in a 400watt closet and soon as U hit the hall U can smell it> I tried carbon, i tried air freshner, and lyson nutra air all at the same time. No HELP. well I said hell with it time to get serious ozone was out the question. so I got this 6 oz ona gel block and WOW my wife constantly complained about the smell and even she is like WOW This shit really really works man. Still waiting on my ONA mist to come. IF U HAVE A SMALL GROW U CANNOT VENT EFFICENTLY WITH CARBON ONA IS A MUST THE BEST SHIT I EVER USED AND IVE BEEN AT THIS FOR 3 YEARS MAN GET ONA GEL NOW!!! No i do not work for them.lol
