Burn them in the back yard and send the buds to me. lol Depends on the medium you use. Whatever you do make sure the trash doesn't get you busted. I have trash pick up at the curb so the leaves and stems get triple bagged and put out with the rest of the trash. I use coco-coir for my medium and I just spread that around in my flower/ vegtable beds outside. VV
