Ran out of freezer room so I'm experimenting with freezing CBD's for later use. From what I can tell - Harvested CBD's aren'y potent for days after picked... I'm learning so not sure about potency and time. Purchased an ice making machine. Blended 20 grams in a Vita Mix with 60 grams of leaves and 48 oz.o water. Strained water two times, then made ice. Now waiting an hour to see if it still makes me my 3 X daily CBD drinks works like it should.
