I have little experience with it, but from my experience with the machine you should keep everything tight and adding that water shot in there makes a little difference.. its so humid when i gotta use this thing. the thing is like an air hockey type thing and the key is to initially pack it all in there in my experience so far. next summer when i harvest my stuff i started mid-late(edited) summer indoors, I'll try it again and give another review. other than that i've always had trouble harvesting my shit during the humid af months and im coastal so SOMETIMES it dries up bad overnight here. I think peoples experience with anything changes in their experience with their climate and changes through seasons. with your years of experience you will be able to understand when it's time to jar and avoid that dreaded hay smell!
you really don't need this device it is just a little air hockey type thing with all sorts of slots in it. It is nice if you want to try it out for a harvest here and there but also isnt the key to drying. Your own experience and measuring humidity when it goes to jar is the most important IMO
realistically i have only had one, perpetual harvest with this during the about 70RH climate i live in during that time. I used this thing I think about 5 to 7 times over, on a perpetual harvest top to bottom, and then again, and the bud that was jarred came out great! Minus one jar that was over-dried and still was great IMO, just a little brittle not lacking taste but didnt taste like it had cured as well either.
my own experience, actually using it.
you could easily overdry your buds using it though.
