These were the lugs and mud lugs off the plants. They were pretty much already full yellow when I picked them. At the time of browning, the humidity was decent, but then we got more rain and the humidity shot up. I don't have a cure chamber, I cure in my shop. These were all dry and brown except for the ones picked last, which were full yellow and limp. I moved them into the house in the bud bags (great air circulation) where the humidity was 48% and temp. 78F to finish drying the stems and finish curing the full yellow leaves. (the dry leaves will absorb excess moisture from the yellow ones still needing to brown up to keep them from molding) Since I can reuse the bud bags, and no electricity was involved, it was a zero cost solution. The yellow leaves are browning nicely and while the stems aren't completely dry yet, they all have the same feel throughout the bag, leading me to believe that they are all drying at the same rate, rather than outside first, as they would do in a pile. I keep the house thermostat at 78F, but run the ceiling fans to keep an even temperature. I've kept the bags under one of the ceiling fans.
For someone with a kiln or chamber, I think you are right, you could color cure in the chamber, move the leaf to the bags for stem drying and kill two birds with one stone. (1) You could free up the chamber for the next load of leaves, and (2) save the cost of running the chamber for stem drying. I could probably dry the stem faster if I moved the bags outside into the sun during the daytime, but they are doing so well in the house, I haven't seen the need. (saves thought and work also) An experiment which I plan to do shortly if the humidity stays high, is to move to the bags as soon as the leaf is yellow but still limp, then move into the house for browning and drying. This will probably require taking the leaf out of the bags once a day and rotating it around, but it could save a crop under certain high humidity conditions.
