often hybridized with distinctive plants.

EARLY PEARL - An indica-sativa
hybrid developed at a midwestern
university. It has a nice, up high, pleasant
taste and is strong. Very fast maturing but it
has fairly long internodes.

BIG BUD - A variety with a dense
smoke, and indica high. It is very high
yielding with a large bud on a compact
plant. However it is very finicky, needs a lot
of light and is difficult to clone. It has been
phased out of the Seed Bank’s catalog but
is still being used by cultivators.

All of these varieties have been
stabilized a bit. They are often hybridized
with each other.

LIGHT

Plants use light as energy to fuel
photosynthesis, a process in which water
and carbon dioxide (CO 2 ) are the raw

materials used to make sugar. Sugar is the
basic building block of all plants. By twisting
the sugar molecule, plants form
carbohydrates, which are more complex
molecules. Plants use carbohydrates to
build tissue. When nitrogen atoms are
integrated into the molecules, amino acids
are formed. These are eventually grouped
together to form proteins.
Light is also used to regulate many
varieties of cannabis' reproductive cycle.
Scientists speculate that the plant produces
