There are a hundred ways to make hash.
The best, easiest one I've found is the x-tractor 1000.
Set it up in an extra shower or anywhere with easy water and a drain, and the hardest part will be waiting for the hash to be done.
It costs a lot more than some other systems, but it is definitely the easiest, and the best yield.
I put in 150 grams of trim, and I've gotten as little as 10 grams to as much as 19.5 grams of high quality bubbling hash.
Kif boxes make the tastiest hash in my opinion, but it's hard to get as much from a kif screen as you can with the x-tractor.
