When I use my newspaper sheets to slow down drying, I forgot to add that I keep them on a cement floor, which is typically cooler than wooden or other flooring. The difference of a few degrees can make a huge difference in the RH of whatever is being dried. Refrigerators can also be handy as they can keep things cool without too much dryness or high humidity...and the air circulation can help with mold. Basically, the best dry is as slow as possible without having it too damp for mold. This allows the cellular functions to last as long as possible and gets rid of excess chlorophyll and nutrients. At least for my purposes and setup, which is usually pretty small.
