with dry ice bubble hash, do I need to freeze what I want to use when I cut her down. or after she's dry I can trim and use the dry trim? or do I need to freeze the dry trim also? and how many bubble bag sizes would one recommend?
When making bubble hash the only difference between fresh or dry is if you want live resin(fresh)or a cured product (dry) for the most part. You'll want to freeze the product in either case for the best pulls. Number of screens/bags is more a personal preference. They are pretty cheap and come in a good variety of micron ranges to work with.
