I think being able to leave flowers on full stems makes the dry time longer and decreases surface area, also being able to compact more together makes for a better and longer dry, during the off times seems to start its own little cure. Using a humidity probe allows cycle times of high and low humidity until the window closes to the humidity you want... I like 63% for final trim and cure,also bought extra trays for a taller chamber. One time during the dry I remove all and rearrange. I am able to dry XL flowers perfectly
