bubble hash, dry-ice hash, rosin press, some sort of extract with a solvent....
I'm a fan of bubble hash. It's a bit time-intensive, but you can probably do 1lb at a time in a a portable washer. Check out any frenchy video on youtube. "making hash w frenchy"
dry-ice hash is probably the easiest, but alot more plant material contamination by compairon, hence the green-colored hash. And, rosin pressing is higher concentration than either hash method. I'd stay away from solvents. Blow yourself up or not know how to properly evaporate it off for safe consumption etc. That's why i like hash and rosin.. no concern of a solvent remaining or fire hazards. buy some cheap mesh bags and a cheap portable washer and you are good to go with a bag of ice or ~0C weather in your backyard. (ice provides cold temperatures so if it's already near 0C, then you don't need ice.)
