Flowering is the final development period of the cannabis plant. The start of this phase depends not only on the growth time you give the plant, but also whether the plant has the right characteristics to support the precious buds it will develop during this phase.
The strictly necessary germination phase is defined as the time it takes for the seed to develop into a seedling. If you are using cuttings, this germination time is referred to as the cloning and rooting time.
The time of germination depends not only on the method of germination. It also depends on the quality of the seed which in turn can be affected by the age of the seed, its fertility and the way it has been stored.
Phase 3 – Flowering stage
The growth phase of a photoperiod variety when grown indoors can be limited by making the plant think that it must flower. How to do that, you will read below.
This process generally takes between 2 and 6 weeks. Ripening is complete when the bud cracks when you gently pull it.
How long the flowering phase lasts depends entirely on the variety you are growing, but it can be said that an average flowering time of both autoflowers and photoperiod varieties lasts 9 weeks.
To briefly answer the question. Growing a photoperiod cannabis plant takes an average of 4 to 6 months. If you grow an autoflower, then it is usually ready to be harvested within 3 months. This does not include drying and ripening which takes about 1 to 2 months.
After another two days, they should have a pair of leaves then continue growing for another two weeks until they begin the vegetation period. If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.
If you’re one of those people that have to have control over everything you might find yourself wondering how long cannabis seeds germinate. The long and short of it is that it usually takes 24 to 48 hours for the cannabis seeds to germinate. If they are placed somewhere moist, warm and dark, like a cupboard or in a propagator. These are ideal places for the Cannabis seeds to germinate and they will crack out of their protective shells.

So now you know how long cannabis seeds germinate, what will happen after?
If you’re growing indoors, you can force a weed plant to flower after only a few weeks when it’s small, or after several weeks when it’s big. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until the sun starts to go down in fall for it to flower and then to harvest.
Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.
When should you grow marijuana?
As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.
When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.
Harvest happens sometime between September and November. This depends on your local climate, as well as the weather that particular year—one year it could be the end of September, the next, end of October, and growers in the Pacific Northwest will have to pull down their crops earlier than those in Northern California.
