The Life Cycle of The Cannabis Plant

Post by Weedguru Higher » Sun Mar 07, 2010 12:37 am

Germination:

This is the initial stage of growth and occurs when your seed’s embryo cracks open and the seedling produces a root. This root fixes itself into the soil and pushes the newborn seeding up and over the soil surface.

Image

Following surface contact two embryonic leaves open outwards to receive sunlight, pushing the empty seed shell away from the seedling. It takes anywhere between 12 hours to 3 weeks for seeds
to germinate. Once the plant has reached this stage it goes into the seedling stage.

Image

Seedling Stage:

After the first pair of embryonic leaves are receiving light , the plant will begin to produce another small set of new leaves. These leaves are different from the last and may have some marijuana characteristics such as the three-rounded finger shaped points.

Image Image

As the seedling grows, more of these leaves are formed and bush upwards along with a stem. Some stems are very weak at this stage and need the support of a small thin wooden stake tied to the seedling with some fine thread. The seedling stage can last between 1 and 3 weeks. At the end of the seedling stage your plant will have maybe 4 - 8 new leaves. Some of the old bottom leaves may drop off.

Image

Vegetative Growth:

The plant now begins to grow at the rate which its leaves can produce energy. At this stage the plant needs all the light and food it can get. It will continue to grow upwards producing new leaves as it moves along . It will also produce a thicker stem with thicker branches and with more fingers on the leaves. It will eventually start to show its sex. When it does this it is time for the plant’s preflowering
stage. It can take anywhere between 1 and 5 months for the plant to hit this next stage.

Image Image

Pre-flowering:

At this stage the plant slows down in developing its height and starts to produce more branches and nodes. The plant fills out in the pre-flowering stage. During this phase of the plant cycle your plant will start to show female or male preflowers which appear where the branches meet the stem (nodes). Pre-flowering can take anywhere between 1 day to 2 weeks. Alternating nodes are a good indicator of sexual maturity

Image

Flowering:

During this stage the plant continues to fill out. The plant will show its sex clearly. The male plant (pic1) produces little balls that are clustered together like grapes. The female plant (pic2) produces little white/cream pistils that look like hairs coming out of a pod. Each of the plants will continue to fill out more and their flowers will continue to grow. It can take anywhere between 4 to 16 weeks for the plant to fully develop its flowers . During this time the male’s pollen sacks would have burst spreading pollen to the female flowers.

Image Image

Seed:

The female plant will produce seeds at this point if she has received viable pollen from a male plant. The seeds grow within the female bud and can take anywhere between 2 weeks to 16 weeks, to grow to full
maturity. The female pistils may change color before finally bursting the seedpods, sending them to the soil below. (Breeders like to collect their seeds before the seedpods burst.)

Image

It is important to know that if the males are separated from the females and killed off then the females will not become pollinated. Let us go back a step and describe what happens here.

Flowering Non-pollenated Females (These produce the buds we smoke)

During this stage the plant continues to fill out. The plant will show its sex more clearly. The female plant produces little creamy/white pistils. The plant will continue to fill out more and its flowers will continue to grow. It can take anywhere between 4 and 16 weeks for the plants to fully develop. During this time though there are no males to pollinate the female plants. The buds will grow larger and develop more resin glands. Resin may drop down onto the leaves and the plant becomes very sticky. The pistils on the buds begin to get thicker and cluster into balls. The reason for the high increase in bud growth is that the female plant is trying her best to attract male pollen. Towards the last days of flowering the pistils will change color Indicating that the plant is ready for harvest.

Image Image

Cycle Times

Given the above data it can take anywhere between 10 weeks and 36 weeks for a plant to grow to maturity. That is, again, anywhere between 2.5 months to 9 months. The most common grow time is 3 to 4 months. All this is dependent on the strain that you choose. Pure Sativa can run anywhere into the 6 - 9 month bracket. Indica can flower in 6 weeks. As you can image a Sativa/Indica plant will fall into
the 2 - 4 month flowering period.

Higher, do you know of them there plants can sprout roots from anywhere along the stem?

some plants can do that and that means if you lay the plant down on its side removing all lower branches but bend the top out of the dirt it can get a much larger root system.

ive done this with tomatoes alot and you get some damn fine tomatoes.

Yes, roots will sprout from anywhere on the stem, but not on the branches.

do you force the pre-flowering period whenever you want?I mean should you wait until the plant is big enough and switch to 12/12 or should you wait some indication such as alternating nodes or male/female preflowers forming?

You can switch to flower whenever you want. You can do it straight from seed if you're so inclined.

will the preflowers start appearing 'after' switching to flower stage? because i think i read somewhere that they can also appear at the end of vegetative growth. Should i wait for them as a sign of maturity(if space wasn't an obstacle and since i dont have a preference on when to force flowering (i am inexperienced))before i force flowering?

If space wasn't an issue and you'd like to maximize your yield, you can veg as long as you want. Just make sure your lady gets all the nutrients she needs as she grows.
