I've decarbed just about every way possible, but this method was supposed to be so much better! I made some RHO a few weeks ago. Last weekend I mixed some with 99% ethylene and drank it, worked very well! I had dried the buds at 200°F for 30 minutes, then cooked the oil post-extraction at 250°F for 25 minutes. I probably have to play with times to get better results but it actually worked quite well. I had a nice, social buzz for several hours.
Edit: Ethanol, not ethylene. Ethylene Glycol will kill you.
