Ya I use Ona. I exhaust into an area that I guess you could call a 'mud room' there's no heating in there it's just attached to the house. Anyways. Sometimes I can get a whiff when I'm comming up my driveway in late flower so I just bought some moisture crystals and the liquid Ona and mix them together. Way cheaper than buying the already crystal stuff. Plus you just reuse the original crystals over and over again. I use the polar one but I'd like to get my hands on the apple. It works. I place it near the exhaust vent so the air passes by it. Don't leave that shit anywhere where the air can get back into your tent. You'll be tasting Ona gel in your weed for sure. It's mega potent
