Curing slowly strips the chlorophyll, im not so sure it effects the resin glands as they can't really store chlorophyll.You actually dry two things and one isn't even needed. The plant and the oil or gland filled trichs. I guess it's the plant that's the hard part, trichs should dry easily and in more diverse ways. To dry a plant you just let it dry, if you fuck up the trichs are normally ok and it's the plant giving a bad taste.
I don't understand how the cure stops, the plant may stop but oil is a different compound it will always slowly degrade or age. If you seperate into hash you see just how oil cures and the plant doesn't do a whole lot.
