I've always used 6-8 bubble bag kits for use by hand. I use the largest size mesh bubble bag first, full of ice and trim and buds, and put that into a 5 gallons bucket with ice cold water. I add ice and agitate regularly. Next we tlremive and squeeze out the bag that is still full of some ice into the first 5 gallon bucket, and then do the same in a second 5 gallon bucket, basically running it twice.
Next I put all the water and thc extracted into the buckets together into one bucket. Put all your remaining bubble bags in order into the now empty bucket, and pour your thc/water mix through. As you remove each of the bubble bags you will have a collection of finer and finer grades of crystal/hash pancakes. Keep them separate and press, cure and dry. It's been a while sorry I don't remember how long they took to dry, kinda depended on size. It's a whole lot of fun, just remember to clean the room
You are using before you start. Anything in the air will end up in your hash
. Damn dog hair got in some of mine one time, totally messed it up.
Cheers.
