i have made hash in several ways , pollinator machine, hand shake, crisalicer, and bubblebags, the weed always needs to be very dry!,, and the fan leaves unless visibly coated in tricomes should be left out, alot of bulk and very little crystals, the best to use is close trim only, and lower buds even,i have thrown in some plants before that a wasnt to impressed with!.
always best to freeze the weed first for a couple of days in the freezer, as thats what you hope to achieve with ice and water extraction, even for the pollinator machines and the hand shake, the freezing breacks of the crystal from the leave , same as making oil with gas! the bubble bag is far by the best method i have found for hash extraction!. exphensive to buy, but many grow shops offer them for hire,
and on the subject of being in the hydro section,,, i grow hydro, and make hydro hash!!!lol
the last one i did was last week, 200 grams of close bud trim made 28
gramms of hash, which aint bad for nothing!.
the bubble bags also grade the hash for ya and in all ya get four very good grades, two not soo good!
the last i did was from superskunk and white russian trim!
it was awesome and made an afgan like soft squishy hash in two of the last bags
very impressed with it , go for it , and have fun!
