I got a source turbo and made some QWET using some older larfy UK Cheese I had from a year or two ago and some Everclear. I followed your recipe exactly and it came out amazing! I'm so psyched!
I used 30 grams of good quality lower buds gently broken up, froze it along with the ethanol and washed it for ten minutes in 750 ml of ethanol. I got three grams of very golden light extract after a couple runs in the Source Turbo. I washed the bud again for a second run for twenty minutes. We'll see what I get out of it. Quality is through the roof!
These cartridges are true one hit wonders. I might have to try that SERVM and see if it's better than the Terp Liquify. They also sent me a complimentary tiny bottle of Blueberry Muffin terps. I added one drop per half gram of extract. I think that was a good ratio. Just enough to give you some flavor without being overpowering or harsh.
@Ripper has your method changed at all? Any new pointers since last year?
