Hey RepoBob....I have done the same with the leftover water...let it settle for a few days...then siphoned off the water...put in a dish and evaporated the rest of the water and ended up with a huge chunk of hash! I tried it and found it to be better than street weed. Did you end up making the butter? What did you do with it? I would love to find a good use for it, I hate to waste anything.
