Kief, Hash, Pack, Brick, Brown, Bowl rubber, sticky icky.
Whatever you call it, its the same thing; and making it is a pretty easy task.
You can use anything from left over cut/trim from harvest, or entire buds.
The Screen Method
You will simply need "bubble bags"
or a mesh screen of about 125-150 micron.
The larger the mesh, the more youll have, but the lower the grade.
With the opposite being true as you reduce screen size. Do not go over 175 is my diagnosis.
Going below 110 is also a pretty bad idea.
You will also need a few liters worth of ice if using bubble bags.
For the screen, suspend it over the whitest brightest paper you can find, and "gently" wave the grass
back and forth across it, the good stuff will go through and the bad stuff will not.
For bubble bags, "which will separate your shake into 'grades'", you put the smallest micron bag in first
then each other in that order untill your bags are in place, then your ice, your shake, and water untill
your bags are 80% topped up. Now vigorously mix with a hand blender for 10-15 minutes and then allow to sit
Fill cellophane with your mixes "or if in grades, separate cellophane" and wrap tightly.
Wrap in 5 layers of newsprint and wet, tape it up. Use a rolling pin, cough leg and then have sex on it :)
whatever it takes to compact and tight that as much as you can.
Rewet the paper, make sure your tape is holding and bake in an oven of 100*F for 10minutes
The Blender Method
Put water in a blender. Add a large handful of leaves, stems, seeds and weak weed. Put it in 3 or 4 ice cubes and blend it for 3-4 minutes or so. Just make sure everything is chopped very finely. Second, you will need a gold reusable coffee filter. Get a large mouth quart mason jar, and strain your Slurpee mixture through it. Once you have strained all the liquid through, run some more water through the leaf material to wash any extra trichomes through.
After a few minutes you will notice a white collection at the bottom of the jar, this is the trichomes. Let the trichomes settle at the bottom for about 20-30 minutes. Next, pour off the top 2/3's of the filtered green water, leaving the settled trichomes at the bottom. Add more ice water to get the green stuff out, and let the trichomes settle at the bottom for about 20 minutes again. Repeat this step one more time. Pour off as much water as you can without pouring off trichomes, filter the resulting trichome/water mix through a paper coffee filter. The trichomes will not go through the paper, but the water will. When all the water has gone through, slightly wet, cold, mass of trichomes will be left. They will be easy to handle and to press.
Never store wet hash! it can mold.
