every post i see says let the cannabutter cool in the fridge over night. To harden and separate from the water. Do I need to let it go that long? Will like 2 hours be fine? Its thickening up but still soft and pliable. Also there are a bunch of small dots of butter floating around in the water. Should I wait a while longer so these specks can float to the top? or are they gonna stay floating in the water?
