G,day
I dont know if this is what you are looking for ,but i am sure i got the info of this site.
if not look up ice hash ,i made some a couple of years ago ,and basically ,mixed my leaf ,and small buds with ice and water ,which also has to be cold ,shook the shit out of it ,put it back in the fridge , to settle , ithink it is better if you have a mixer or blender,but it worked ,i remember having to do it a couple of times then removing the crap ,filter via a coffee filter ,let it sit again until you see the green sediment on the bottom of your jars, i then drained it very carefully until only a small bit of water was left ,then i just tried to get as much fluid that was left of with dipping paper towels on the edge of the fluid, left the remains to dry and got some nice hash ,after a bit of hassle collecting it and wrapping in tin foil ,and pressing ,all of this is of a very bad memory ,but the hash was great ,i didnt get heaps ,but better than the crap that i started with.
i would do it again as bubble bags cost to much for the amount i grow. and everyone was stoked when they had a try.
