THE PLANT

Years ago people grew seeds from their
best stash, mostly sativas, originating in
Colombia and Mexico. These plants grow in
a classic conical shape, with long spreading
limbs at the bottom and a single main stem
on the top. Since then, Americans have
discovered many other varieties such as
single-stem Moroccans, asymmetrical
indicas, and variants such as "creepers."
There are thousands of varieties of
marijuana. They have different potential
yields, highs, flower size, bud structure,
ripening time, height, leaf shape, color,
bushiness, and amount of light required for
adequate growth.
In much the same way that the
environment affects the yield and flavor of
grapes, it also affects the genetic potential
of marijuana. The taste, quality of the high,
yield, and color are all subject to
modification by the environment. Some of
the factors include amount and quality of
light, water, temperature, amount, ratios
and kinds of fertilizers or nutrients, and
