Hash Oil: Field Expedient Extractions

I want to harvest cola's only from my main crop, 300 Danky Doodle X BC Skunk and 340 Early Sativa. Thats a lot of extra side branches I don't want to dry, cure and store.
I want to do a Guerilla Extraction of these branches, I figure having a low per plant yield. I will go into a open field in the forest, find a good location. Pull 20-25 clumps of vegetation at 4' apart and drop 2 seeds into each bare spot. I will simply step on the two seeds into the dirt and leave. I will do this in the early spring in a few weeks. I will not return until July when the males will appear. They will receive their just reward, and I will leave until mid- September. I might try and squeeze 1 or 2 foliar feedings, but they are s.o.l. about water, and thats one of the most important requirements. I am relying on mother nature and the marijuana tap root. Therefore I figure on a lower then average yield, still 640 possible, guess closer to 280 females. Thats alot of side branches, butane is too expensive.

I have built a still out of a pressure cooker and copper tubing. Maybe I can brew enough moonshine to use as a solvent, to melt the THC. The best part of the idea is I don't have to remove the solvent, I can thin it to a marijuana whiskey, or marijuana ladies drink. Get drunk and high.

Any ideas are welcome

I found something about hot water extraction. I did not find the answer I was looking for: yield or potency. Has anyone any ideas on this hot water method?

Your best bet is to use high proof alcohol as a solvent.
