Set your 25-micron drying screen(s) on some paper towels and set them aside. Your washing machine came with a 220-micron bag, which you will layer with ice and cannabis. Put ⅓ of the bag of ice in the bottom of the bag, add your cannabis, and then another ⅓ of the bag of ice on top. Close the 220-micron bag and use the string attached to the bag to tie the zipper closed.
If your machine didn’t come with a 220-micron bag that fits inside, just layer the ice and cannabis directly in the machine. Double check to make sure the bag inside is completely closed and tied before the next step or all your cannabis will come out of the bag into the washer. There should be a mark on the side of the washing machine that tells you how high the water should go. When we’ve filled it to the high mark we’ve had it leak out the back once everything starts mixing and churning. Even at the low mark, there can still be too much water after a bit of the ice melts. Set the machine to mix up your cannabis for 12 minutes and wait for the cycle to complete. Let the machine sit for another 10 minutes afterward to let the trichomes sink to the bottom.
Grab the unused bucket and stack the remainder of your bubble bags inside. First insert the bag with the lowest number (25-micron), then put the next biggest (73-micron) bag inside that, and finally put the (160-micron) bag inside that. If you didn’t use a 220 bag in the washer, or if plant material somehow escaped your bag while in the washer, you’ll need to lastly insert a 220 bag, which will filter away the larger plant matter. Note: Some bubble bag sets come with 5 bags and some come with 8. We use the 5 bag set, but we don’t use all of the bags that come with it. All bag sets come with 25, 73, 160 and 220, but the size of the other bags differ depending on who’s selling them. Some sets come with a 45, 90, or 120 and many growers like to use those bags. However, we only use the 25 (good stuff) 73 (the best stuff), 160 (not bad stuff), and 220 (cleans out the junk) bags. The most important thing is to start with 25 and make sure each bag after that goes up in number. Pour the weedy water from your washer into the bucket containing your stacked bubble bags. Your washer has a tube meant to dispose of old water; this is perfect for pouring your weed-water into the stacked bags. You might need to suck on the tube a little to start the siphon. If you had to add the 220 bag, lift that out before the next step. The 220 bag will remove the large bits of leaf and other plant matter. Keep this plant matter because you will run it through the whole cycle again. Allow the water to drain through the 160 bag for a few seconds. Carefully pull up just the 160 bag and place it into the empty, clean work bucket. Use your sprayer (or mister/cup) to wash the hash towards the center of the bag. Carefully pull the edges of the bag down over the bucket until the bottom of the bag (where the hash is) is stretched across the opening of the bucket.
Use a metal tablespoon to collect the wet hash and place it on the drying screen. Remove the 160 bag from the bucket and set it aside.
Repeat for the remaining bags, removing each one slowly one at a time and collecting the hash, ending with the 25 bag. I always try to label which hash is which so I can compare them later. The next step is to do a second run with the same bag of plant matter.
