Can you give details on how you do it? How long you soak/wash, etc?
I just made another batch this weekend and am probably starting another batch tonight with some of my premature, accidentally re-veg'd, chronics I harvested early. I used <2 pints of iso, 17g of trim/popcorn, and quick-washed it 3 times through the same 2x coffee filters. I freeze it for 45 minutes, crush it, soak for 45 seconds, shake for 45 seconds, and strain. Throw the trim back in the jar and repeat twice more. I ended up with 1.9g of QWISO after letting it dry ~ 40 hours. I have ~60g more of trim/popcorn ready right now for butter/hash and 2 more premature/reveg plants that have been hanging for 10 days to trim. I haven't posted pics of the final product in my journal yet, but will do it later tonight or tomorrow.
