Mine does both. Realize, curing is merely the aging process once you have dried to your prefered moisture. Exchange of air, and maintenance of the RH your “dry buds” are at for a curing period. It doesn’t need to be a jar or bag, just a vessel that can maintain a set RH. By adding / controlling a humidifier, it changes the game. Before that, best I could do was dry, and hope to not dry too fast. Then into jars and get burped (I even made an auto burp system). People put Boveda packs into jars to maintain humidity levels, this is no different.
By adding a “set” variable, and a “variation” variable, I can “set” the RH to 60%, and a “variation” of 1%, which would keep the dehumidifier on above 61%, and the humidifier on when its below 59%. By maintaining a 60% RH at all times in the tent, the tent itself can be used as a curing vessel (Large operations use entire rooms, this is just scaled down).
Since I can also save the readings and graph them, its interesting to be able to see when the drying process is done. Essentially, chop and trim and put a plant in. RH will spike to the mid 70’s, dehumidifier is turned on, RH drops to 60%, dehumidifier turns off, and RH rises. The more plant material, the higher / longer the spike. As water is removed and the bud gets to my desired moisture, the spikes get smaller and smaller and less often. When RH is stable at 60% you know the bud is finally dry and is now curing. Depending on the season, my houses RH is 40% to 80%, but by keeping the mini humidifier in the tent for low RH periods, the buds won’t dry to the point of no longer curing (I wanna say most aim for moisture in jars of 58-60%, and this maintains that). The humidifier hasn’t run in months now, but if it was december / january, it would be off for the dry, then on periodically during the cure. Ambient RH plays a big part in my house.
