PG 35. Ed Rosenthal's Marijuana Grower's Handbook... I am not making this stuff up. Go to Oaksterdam and they actually teach the course that way..... Not sure where you get your info from but Books are a good start...
Cannabis belongs to the
genus Cannabis in the
family Cannabaceae and includes three species,
C. sativa,
C. indica, and
C. ruderalis (
APG II system).
[5] It is typically a
dioecious (each individual is either male or female)
annual plant (life period: April-September).
[6][7][8]
C. sativa and
C. indica generally grow tall (some varieties reach 4 m) and their females start the production of flowers rich in THC (1% to 23%) as the season changes from summer to autumn.
C. ruderalis is very short, produces only trace amounts of THC and flowers independently of the
photoperiod and according to age.
[9] However, commercial
cross-bred hybrids containing both ruderalis, indica and/or sativa genes exist (usually called autoflowering), the "
low rider" being the most famous. Auto-flowering marijuana strains are considered advantageous by some growers because of their discreet size, short growing periods, and the fact that they don't rely on a change in light schedule to determine when to flower.
