There is a smell machine i bought that gets rid of smells. I swear it's f.....g amazing. When dry you will always get a smell, carbon filters are great. But, you can smell it. (The carbon filter)
The odour Neutralizer. The machine itself is very cheap. Its the oil. Like 100ml is 70euro.
Altogether the kit cost 100 euro. And, its not like spraying something that covers the smell up. This eliminates end odour. And leaves a fresh smell (you wouldn't be able to say, that was just sprayed) I seriously had my doubts but its won which choice awards (not handed out to any owl products). For instance my grow room. I used plagrons fish shit and my god. The smell in my grow room was nasty. I had this in it, came back 6hrs later. (This was my 1st true experience, idk maybe the smell was gone earlier but I couldn't believe it.
A carbon filter and tent, is great.. but I plug this machine outside inside my grow room I've done away with filters.
A 100ml running 24/7 lasts about 6-8 weeks. Its expensive but, if you wanna truly eliminate not scrub the smell. An elim machine will work wonders if you're worried about opening the door and somebody getting the smell of dying weed (as we all know, there's a massive dif between smoked and growing/drying MJ
20c is the higher end of drying temps. Keep your RH around the 60 area. Hang it whole, untrimmed to prolong the drying time a common problem ppl get when growing home grown is drying. And end up with bush whack. The bud when held close to the nose smells like hay. The Kit look into it in the future. To get through this grow, yes that temp is fine. No direct air blowing on the bud. The exhaust alone (that air exchange is perfect for drying)
Good luck.
