Marijuana Horticulture: The Indoor/Outdoor Medical Grower's Bible

screens with 96 percent pure alcohol so no oil-based resin remains. Hang to dry.
    Moisture must quickly be removed from the resin powder to prevent mold. Crumble it up and spread it out on a screen or hard surface. I like a screen because you can sop up moisture by pressing a paper towel under the screen.
    Another option is to hand press all the water out of the ball. Continue working the wet powder until it transforms into a cohesive ball of oily hash.
    Or you can hand press until you have a solid ball. Keep squeezing and pressing, water will become visible on your hands.
    Remove the last bit of moisture by flattening out the ball and putting it in the freezer. Freezing expands the volume of water, which will appear on the surface of the hash. Simply wipe off the ice when you remove the hash from the freezer.
    When you press powder, the resin crystals will break and the oil will be released. The mix will darken as it oxidizes. The resin crystals from very fresh leaf will remain white, a very high quality.

Water Hash with 15 Bags
    The guys at THSeeds in Amsterdam, Holland, are expert hash makers. They taught and inspired my good friend Moño to strive to make the absolute best possible hash. Moño uses bags from several manufacturers to separate more and different grades of hash. Moño uses 15 different bags and extracts more resin than anybody else! Moño’s work is so impressive that we decided to profile his extraction process here.

Get all your supplies ready before starting a water extraction run. A bathtub and a clean bathroom make an excellent water hash-making environment.
    More wet sieves separate more and different qualities of cannabis resin. Resin heads are different sizes. They fall through different size pores in a sieve. You can separate different sizes of resin glands with different size wet or dry sieves.
    Separate hash with progressively smaller sieves so smaller screens do not clog with wet hash.
    Moño has a full array of separating bags from several manufacturers. His laboratory is set up in the bathroom, with the tub the center of attention. He keeps the “laboratory” clean with a shower head attached to a flexible hose. Here is the array of bags he uses to separate the trash from the hash.
    The “work bag” is the one that contains the bulk of the processed resin-less leaf. The work bag is usually drained and set aside so the debris inside can be discarded at will.
    Moño likes bags with rigid sides. They perform better because they retain their shape inside the bucket and are easier to use when only oneperson is making water hash.
    The process is done in two steps. First, he washes and separates the resin glands from the marijuana foliage using six screens. This process washes out virtually all of the foliage and contaminants.
    The hash-laden water that is left over after passing through six bags is separated again by running it through eight more bags. The resulting hash is very clean.
    Instructions for a 15-bag kit The basic process is the same for each bag. You can add more or use fewer bags. Make sure to have everything ready before you start. You will not have time to look for supplies once you start this process.
You will need:
    Bags with silkscreens
    5-gallon (20-25 L) bucket with lid
    Kitchen mixer - Use the kind with paddles for mixing. Do not use the kind with a short chopping blade.
    Paper towels
    Dinner plate
    Plastic card
    Large mixing spoon
    ± 4.5-11 pounds (2-5 kg) of ice cubes, enough to keep the temperature down to 41 °F (5°C).
    Make sure to have plenty of ice, and do not add too much cold water before adding ample ice. Keep the ice mixed with ice-cold water to make it last longer.
Start First Run
    Before you start, remember to clean out each bag and rinse thoroughly with plenty of water. This little bit of timely cleanup will keep gooey resin and debris from clogging sieves and will avoid laborious scrubbing (with alcohol) later. Set bags out to dry. To avoid fungus, make sure the bags are completely dry before storing.
End first run

Use fresh-frozen bud trim. You can use large leaves, but they have little resin.

Fill the bags at least halfway and above the level of the screens. The screens must be covered with water before introducing plant matter.

Pour in the cold water and ice.

Add the plant matter.

The cannabis will float and take a little while to absorb the water.

Add ice and a bit more cold water to bring the
