Hash is formed when the cannabis trichomes (aka kief) are concentrated and compacted together. There are many ways to successfully remove the kief from your flower as well as many ways to compact/press/distill the kief into the desired form of hash.
Of the many ways to collect kief from your flower, we recommend the DRY SIFT SCREEN METHOD and DRY ICE BUBBLE BAG METHOD.
Whichever method you choose, make sure you get everything out of your flower!
Depending on what type of extract you would like to end with (Shatter, Rosin, Budder, CO2, Crumble, Wax) will determine how you turn your collected trichomes into different types of hash.
