Have you tried the "low & slow" method? Just put them in paper bags in the fridge. It takes longer to dry, but the terps are improved, IMHO.I had to stick a 4" flex duct into the end of the 8" flex duct coming out of my inline fan (output side), then run the 4" flex duct to my drying closet to get warm output air flowing through; eight days on the drying rack and the buds were still as damp as they were the second day.
