How-To Make Washing Machine Hash

Here you can read the original english version of Jorge Cervantes text.

On a recent trip to the tropical region of Colombia, I was able to
record how expert grower friends made hash in volume.  They
learned this technology from Mila at the Pollinator,  This information is very useful to process the
leaf that is left over after the harvest.  Using an every day
washing machine will save hours of laborious work.  Following all
the steps and paying attention to the temperature of the water in this
simple process will extract all the remaining cannabinoids from the

The best bet is to purchase the proper bags that have been
tested.  Mila makes different bags for outdoor and indoor
crops.  Plants grown outdoors have smaller resin heads than plants
grown indoors and require a smaller mesh bag to collect the resin.

A washing machine filled with cold water is used to agitate the leaf
and glands that are located inside of a silkscreen zipped Ice-O-Lator
bag.  This process separates the resin glands from the green leafy
material.  Once separated, resin glands fall through the sieve
into the washing machine water.  The leafy material stays inside
the bag.  The hash-laden water is evacuated out the washing
machine’s drain hose and separated from the water in a simple filtering

The machine is filled with ice and ice cold water.  Cold water is
used to keep the resin glands intact and facilitate separation from the
leaf.  The principle is easy.  Resin is an oil base and leaf
is a water base.

How they did it

First they place paper bags of 500 grams of leaf in the freezer for 1.5
hours.  Cold temperatures make the leaves brittle, which allows
them separate from the resin glands easily.

Next the two, 500 gram bags of the cold leaves are loaded into a
“zipped Ice-O-Lator bag.”  They fill the drum of the washing
machine with very cold water.  Chunks of ice the size of your fist
are added to the water until the desired temperature of 4 degrees C. is

The cold temperatures allow the oil-based resin to separate from the
leaf more easily.  Two zipped Ice-O-Lator bags are loaded into the
drum and the machine turned on to agitate for 10-12 minutes.  Two
bags are used to keep the machine in balance.  As the machine
agitates the bags, resin glands slip out through the mesh of the bags
into the water.

The next step is to evacuate the resin-laden water out the drain. 
The drain water is sifted through an Ice-O-Lator bag to remove any
remaining leaf.  The water is collected in a larger bag placed in
a large container.  Once all the water is evacuated, they lift the
large bag from the container.  The “clean” water flows out the
sieve in the bottom of the big bag and the wet resin stayed in the big
bag.  They squeeze the last of the water by hand out of the big
Ice-O-Lator bag and the resulting un-pressed hash is set out to
dry.  Every one kilo bag of leaves yields 30-40 grams of dried
resin. In a single 14-hour day they can process 100 kilos of leaf and
transform it into 3 kilos of quality resin that is later pressed into


1.Use an every day washing machine.

2.Fill the “zipped Ice-O-Lator bag with leaf and place in the washing machine filled with cold water and ice.

3.Drain the hash-laden water and strain through an Ice-O-Lator bag.

4.Remove large Ice-O-Lator bag from the container.

5.Squeeze excess water from the large Ice-O-Lator bag.

6.Dry the wet resin.

Profile of a Variety

Northern Lights – Was developed by “The Indian” on an island in the
Northwest.  He started with 11 seeds and named them NL #1, NL #2,
etc.  Of the plants, NL #5, NL #8 and NL # 1 were the best in that
order.  Neville shuttled clones back to Amsterdam from Seattle, WA
in the mid 80s.  Today, NL #5 is the main variety of NL breeders
use.  Northern Lights #5 is often crossed with other varieties
including: Blueberry, Haze, Juicy Fruit and Jack Herer.  Varieties
are available from Sensi (who has registered the name), Canadian
Professionals and Nirvana.

Northern Lights #5 is an absolute must if you grow indoors.  This
potent user-friendly plant is also very popular among commercial

Taste – Strong, full bodied, sweet, piney, hashy
High – Body stone, couch-lock,
Potency – very strong, great resin production
Genotype – predominately Afghan indica/Thai sativa, very stable
Culture – easy to grow, can be pushed with fertilizer, 
Odor – Sweet piney
Habit – High flower to leaf ratio, compact buds, purple tinge to leaves as it matures
Yield – very good, a favorite among commercial growers
Disease/pest resistance – somewhat resistant to thrips and spider mites, best to cross with sativa
Indoors – 60-65 days,
Outdoors – Early October
Ease to manicure – Easy and fast
Water hash quality/quantity from trim – good but low volume
