How to take and use pollen

administering pollen to your female plants in a shared

recommend doing this only after you have closed the
ladies up for the night. Shut off any fans in the
vicinity, as pollen is an airborne 'agent' and will
travel for quite some distance if allowed.
Also be considerate of household members
that are sensitive to
Place a dry, sterile, open
bag/container under the opening male flowers.
Gently tap the stem with a finger. The
pollen will slowly settle into the container. (If you
are careful, only a few flowers will fall into the mix.
Remove any flower/plant parts that
land in your container with the pollen. Tap them off
gently before removing, to recover the pollen.
Dilute pollen with sterilized flour at a four-to-one
ratio. This will allow more coverage if required

[Also, it is a good idea to
isolate your pets during this time. I had a cat run in
once when I was collecting pollen and after I chased it
out, it promptly ran downstairs and into my Flowering
room. A month later I had some very unusually crossed
This is a real easy and practical method for
harvesting a small amount.
Pollination disclaimer: This
method is not recommended for everybody.
Cross-pollination is often a result of pollinating
plants in the presence of other females. Proceed at your
Due to weak branches, space and size
considerations, etc., it may be necessary to pollinate
your plants without removing them from the others. If
possible, I would advise removing the female to be
fertilized prior, but when that isn't possible, this is
a good alternative. Step 1
till the grow lights go off as scheduled, and shut down
all of the fans. Adjust your timers to eliminate
'surprises'. Eliminate any drafts in the outer and
adjoining room and shut off your furnaceAC. The room
must have zero air movement before you begin. Place a
small garbage bag in a pocket at this time, later you
can put all of the pollen 'tools' inside it when
Strategically locate the female(s)
to seed next to each other and against a wall earlier in
the grow. Now prepare a clear plastic drop cloth to
isolate these plants from the rest of the garden. The
plastic featured here is 4' high and 7' long.
Tape a straight edge against the far side of the
tarp so that you can anchor it against the wall
securely. You do not want it to come down! Use the
thinnest plastic you can find to avoid excess moisture
and damage to the plants. Because it is thin, be very
careful to avoid damaging it. Step 3
After arranging your divider by draping it loosely
between the plants, (do not anchor it yet), mist the
floor, net pots and buckets with distilled water. This
will neutralize any errant pollen that drifts by or
lands on the floor.
Thoroughly mist the other
plants that you do not want to pollinate, being careful
to avoid blowback on the plants to be fertilized.
I prefer to wear tight-fitting
clothes during this procedure to reduce pollen transfer.
Carefully retrieve the pollen container, put the brush
inside (a Q-tip will work for smaller amounts.) and
place it into a larger, clean, storage bag. After
sealing it shut, wipe the outside with a damp cloth to
remove any pollen. This is important, you do not want
any pollen to escape during the trip to the selected
plants. Step 5
Select the branches
that you intend to fertilize and label them with
computer labels. This will aid in identification later.
Avoid going overboard here. A single MJ plant is capable
of producing several thousand beans; only pollinate a
few depending on your needs.
Make sure that the branches to be pollinated are in
an area that will get good light coverage. Avoid
pollinating the extreme lower branches, as they will
likely not mature into viable seeds. Step
While wearing gloves, position the bags nearby
and below the branch and lightly coat the paintbrush
with pollen. While holding the brush a short distance
(3-6") above the target bud, lightly tap the brush,
releasing pollen onto the fertile flower(s) below.
Do not contact the flowers directly with the
brush. The 'tap' is similar to tapping off the ash on a
joint, be careful, a little pollen goes a long way. For
interior buds, simply tap the end of the brush lightly
against the stems.
Try to select branches that are nearest to a wall,
to avoid direct contact with other non-pollinated
branches. Cross-pollination will occur anyway, but
usually only a few extra seeds are a result.
When you are satisfied with
the coverage, seal up the inner bag, remove your gloves
carefully and place them in the larger zip lock before
sealing it as well. Now place the bag into the clean
garbage bag that was previously secured in your pocket.
You may wish to remove your shirt slowly and
place it in the bag as well.
Keep a wet
washcloth nearby to wipe off your face, arms, legs and
other pollen magnet areas. Doing this will reduce the
spread of pollen as you leave the area. Remove the
pollen bag from the room and return after washing up.
Secure the far end of the plastic
barrier to the wall. Be careful to do this slowly to
avoid stirring up the air/pollen. Secure the end closest
to the door using squares of stiff cardboard and tacks.

them in for the night, making sure that the fan(s) are
still disabled. You may need to raise the lights during
the lights on period to compensate for the lack of fans.
This continues for 48 hours. On the third day's
lights off time, mist the fertilized plants thoroughly
to take out any viable pollen that remains behind, in
the morning turn on the fans and adjust the light(s) as
Remove the plastic divider after one week when you
are certain that there is no contamination
Remember at the end of the grow to
thoroughly clean your grow room with a damp cloth to
remove all traces of pollen.

weeks later, you should have a bunch of viable beans to
grow or share with your friends and
