Dude, I literally just woke up and the first thing I did was check on here to see if there was any new information. I wasent quite prepared for my mind to be fully blown wide open like it just was when I read your post!! Haha. That is pure genius!

I always thought it was interesting that I could leave alcohol in the freezer to keep it cold without it freezing like water or most other things would! And this method makes use of that very low freezing point of alcohol and somewhat higher freezing point of the water and other parts that are unwanted it sounds like, if I understand all of this correctly. It's all new to me though because now that I hear the method and see its results I just want to know all of the reasons behind it and why this works. You don't necessarily have to be the one to explain it to me me in depth, I just need to know and will now be investigating more deeply into the reasons behind the method you have just shown me. So does the THC also have a very low freezing point which makes this method possible? Or does it not matter because its degree of solubility in alcohol is much higher than that of the other impurities? Or is it because most or all of the water soluble aspects and impurities of the plant are Trapped in the frozen water of the plant at that temperature?? Which prevents them from going into solution with the alcohol, and since thc is not water soluble it is saved from being trapped frozen with all of the other water soluble material? Which then in turn allows it to go into solution with the alcohol at that temperature while the rest is still frozen? Damn man, this really has my gears turnin.

My biggest question would be, and I'm sure Graywolf or you have probably already thought this through and covered this angle, but: is two 3 minute washes at that low of a temperature enough to extract most of the goodies? I'm worried about the yield being low, although this really seems like the way to go for the purest oil possible using ethanol as a solvent. This is a question like a student to a teacher. Not like I am questioning the feasibility of this method. It just has me very intrigued. I am very thankful for you taking the time and sharing this knowledge with me my friend.
