You can if you'd like to. After 4 days dry/ 4 days cure, it comes out dry enough to trim. If you don't want a flat spot on your buds, after day 2, flip them over. I really don't care about flat spots, it's going into Grove bags after it comes out, and my grinder can't tell the difference.For the Cannatrol, is it possible to hang branches and dry trim after the 8 days? I assume so, just need to get a hanging rack of some kind. I'm not privy to wet trimming and laying buds on flat surfaces. Otherwise that seems like a deal honestly for anyone running less than 2 lbs per harvest and living in hot climates. Holding a whole room at 60/60 here for 2 weeks is expensive.
Having an environment that is completely adjustable and "set it, and forget it" has worked out nicely, and a lot better than my old drying room which has served well over the years, but a pain to control and keep adjusted to the sweet spot.
Personally, I wet trim everything down into nuggets, run it thru my Centurion trimmer, then into the Cannatrol. I fit almost the 2.2#'s they say will fit, the 6 trays were packed. I'll have a final dry weight tomorrow night after work when I pull the 1st batch out. I've got a bunch sitting in the freezer waiting once this 1st run is done. Then I'm going to run 3 different strains on the next batch, and do a nice run of "fresh frozen" bubble hash while the next batch is going thru dry/cure.
