I started reading it last night. I considered QWET for my carts, since I was using alcohol to winterize anyway, but didn't want to get all that chlorophyll. Figured if i extracted with no chlorophyll by pressing rosin, i could then wintetize without worrying about it... but I see you have been working that color issue out...with spent rosin pucks even.
I think we're both working on the same issue... Producing carts without any PG, PEG, VG, Etc. I like what you're up to! I use just enough Liquidizer to allow the bubbles to work themselves to the surface because I want to limit ANYTHING extra I add.
