Seedling stage:
The second pair of leaves begins the seedling stage.
They are set opposite each other and usually have a single blade.
They differ from the embryonic leaves by their larger size, spearhead shape, and serrated margins.
With the next pair of leaves that appears, usually each leaf has three blades and is larger still.
A basic pattern has been set.
Each new set of leaves will be larger, with a higher number of blades per leaf until, depending on variety, they reach their maximum number, often nine or 11.
The seedling stage is completed within four to six weeks.
Vegetative Growth stage:
This is the period of maximum growth. The plant can grow no faster than the rate that its leaves can produce energy for new growth.
Each day more leaf tissue is created, increasing the overall capacity for growth.
With excellent growing conditions, Cannabis has been known to grow six inches a day, although the rate is more commonly one to two inches.
The number of blades on each leaf begins to decline during the middle of the vegetative stage.
Then the arrangement of the leaves on the stem (phyllotaxy) changes from the usual opposite to alternate.
The internodes (stem space from one pair of leaves to the next, which had been increasing in length) begin to decrease, and the growth appears to be thicker.
Branches which appeared in the axis of each set of leaves grow and shape the plant to its characteristic form.
Preflowering stage:
This is a quiescent period of one to two weeks during which growth slows considerably. The plant is beginning a new program of growth as encoded in its genes. The old system is turned off and the new program beings with the appearance of the first flowers.
Flowering stage:
Cannabis is dioecious: each plant produces either male or female flowers, and is considered either a male or female plant. Male plants usually start to flower...before the female; however, there is sufficient overlap to ensure pollination.
First the upper internodes elongate; in a few days the male flowers appear. The male flowers are quite small, about 1/4 inch, and are pale green, yellow, or red/purple.
They develop in dense, drooping clusters (cymes) capable of releasing clouds of pollen dust.
Once pollen falls, males lose vigour and soon die.
The female flowers consists of two small (1/4 to 1/2 inch long), fuzzy white stigmas raised in a V sign and attached at the base to an ovule which is contained in a tiny green pod.
The pod is formed from modified leaves (bracts and bracteoles) which envelop the developing seed.
The female flowers develop tightly together to form dense clusters AKA buds, cones, or colas.
hermaphrodite, or hermie, is a plant of one sex that develops the sexual organs of the other sex.
Most commonly, a flowering female plant will develop staminate flowers, though the reverse is also true.
