|Marijuana Seed Germination:
Marijuana seeds require moisture, warmth and darkness for successful
We recommend you use clean water. Most municipal
water supplies have clean, pH neutral water that is very
suitable for germination. A small amount of chlorination
is beneficial for killing a lot of the parasites in the
water. If the local water supply is not of good enough quality
to drink then don't use it to germinate seeds. Bottled spring
water, without additives or carbonation, is usually a good
source of water for germination.
For best germination results, fill a glass with clean,
room temperature water. Drop marijuana seeds into the water. The seeds
should be left to soak in a dark warm place (65 - 80 degrees
F). A kitchen cupboard is usually suitable. Check the seeds
about every 12 hours. Tap down the seeds that are floating
with your fingertips, don't worry if they continue to float.
Usually within 48 hours the seeds swell and split their
outer seed casings. DO NOT continue soaking after the white,
initial roots are visible at the crack in the seed casings.
The seeds are ready to plant at this point. Soaking the
seeds until the roots are exposed can result in stressful,
early root damage.
Plant the seeds in a clean, pH balanced medium. The medium
should be loose and light with very good drainage. We recommend a blend of Perlite, vermiculite
and sphagnum moss. This can be purchased premixed and can
be used alone or mixed with light, sterilized potting soil.
Marijuana seeds should be planted about 1/4 to 1/2 inch deep in containers at least
4 inches deep to allow the initial tap root to grow straight
down. The container should have drainage holes to prevent drowning the seeding. The medium or soil
should be thoroughly damp, but not soaked. High humidity is essential to
good germination rates.
Keep the planted seeds covered with clear plastic. Place
the planted seeds under horticultural lights or a cold frame
in a warm humid environment (20 - 25 degrees C / 67 - 78
Remove plastic covers, once the marijuana sprouts have cleared the
soil surface and the first true serrate leaves are forming.
Keep medium or soil damp and fertilized with quarter to half strength
vegetative fertilizer during this stage and watch'em grow.
