Hash question

Could I take a plant harvest it throw it in a freezer for a few days and then wash it in my bubble bags and get like a live resin ice water hash?

I would skip the freezer and do Fresh Chilled Bubble Hash. Put it in the fridge (no more than a week), then make your weed, ice, water solution. Let it sit for 20-30 minutes, then make your bubble hash. Putting in the freezer makes it too green for me. The freezing breaks the cell walls and lets the chlorophyl out. Just get it really cold, then use LIGHT agitation.
