moist at all times.
Heat
Marijuana germinates rapidly when the
planting medium is kept at an even
temperature. Room temperature, about 70
degrees, is best. When the medium is cool,
germination slows and the seeds may be
attacked by fungi or other organisms. With
high temperatures, seedlings grow thin and
spindly, especially under low light
conditions. This occurs because their
growth rate is sped up by the heat, but the
seedlings are not photosynthesizing
enough sugar for use as building material.
Light
Once the seedling breaks ground and
comes in contact with light, it starts to
photosynthesize, thus producing its own
food for growth. When the light is dim, the
plant stretches to reach it. In the wild the
seedling is in competition with other plants
which may be shading it. By growing taller it
may be able to reach unobstructed light.
However, a stretched seedling is weaker
than one with a shorter but thicker stem
and has a tendency to fall over. Seedlings
with ample light grow squat, thick stems.
Seedlings can be started in constant bright
light of the same intensity that is to be used
for their growth cycle.
Some growers recommend that seeds
be germinated in a napkin or on a sponge
and then placed into the growing area. This
method risks damage to the seedling in
many ways; the delicate plant tissues may
