First, take your seed starting pot, and fill it to about 1/2" below the
top edge of the pot with already-moistened fine seed starting or light
potting soil.
Next, using a small wooden dowel or similar object,
make a few very slight indentations into the soil,
each a bit wider than a seed, and evenly spaced out.
Now place one seed in each slight indentation, pressing very lightly
on the seed so that the bottom of the seed is against wet soil, but
not hard enough to push the seed under the soil.
Next, using a very fine mist, or use just the wet tip of your finger to
drip a couple of drops of water on each, get each of the seeds wet.
Now, cover the top of the pot with Saran wrap or similar plastic
wrap, to hold in the moisture and humidity (you will notice
some condensation on the underside of the plastic wrap after a while if
this is done properly)
Keep a close eye on your seeds, and very carefully add a little water
as needed (again using a very fine mist or your fingertip), to keep
the soil, and most importantly, the seeds, moist.
Using this method, even with some of the rarer C. pubescens varieties,
you may see the first tiny white radicles starting
to sprout from some of your seeds within as little as 5 to 6 days!
Once the radicles start to grow, you should place a tiny bit of
moist potting soil, a tiny bit of bark, or something similar
on top of the seed coat to hold it down. The reason for this
is that one of the main risks of using this advanced technique
is sometimes getting seedlings stuck in their seed coat,
doing this will help the little seedling extract themselves.
You should also scoot a little bit of moist soil over the
end of the radical, to help what will become the root of
your seedling get itself anchored into the soil.
One you start to see tiny leaves emerge from your new seedlings,
you can then remove the plastic wrap. That's it!
