weed growing phases

Vegetative stage length: 3-16 weeks

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.

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.

Seedling stage

If you’re growing outdoors in the Northern Hemisphere, growers usually get their seeds between February and April, and you should start your seeds by the end of April. Some growers will start their seedlings inside in a more controlled environment because seedlings are more delicate, and then put their seeds in the ground outside once they’re a little bigger. If you’re growing clones or autoflowers, you have a grace period of another month or so. Plants usually need to be outside, in the ground, by the end of June.

Be very careful to not overwater the plant in its seedling stage—its roots are so small, it doesn’t need much water to thrive.

The weather will start to turn and the sun will begin descending in the sky as your plants fatten up with sweet, sticky buds. It might be tempting, but wait until around the Fall Equinox to start harvesting.

As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.

The growth stages of marijuana can be broken down into four primary stages from seed to harvest:

If you’re planning on cultivating your own weed continuously, you’re going to need some more seeds. We mentioned removing the males from your cannabis crop, and this means that your females won’t be pollinated and won’t be producing seeds. As a result, it’s unlikely that you will have your own seeds to work with.

Once you have your feminized seeds, it’s time to germinate them. Each and every seed contains a cannabis plant just waiting to emerge, but it will need some tender love and care in order to do so. Seeds need heat and water in order to sprout; otherwise, they will remain dormant.

Once you have completed your first growing cycle, you will be rewarded with a potent, delicious bud. So what happens now?

If the plant’s stem swells, it stops producing calyxes, and the yellow leaves fall off, then it’s too late. The cannabis is basically useless at this point.

When the plants flower, they begin to produce a sticky resin on the leaves. Trichomes will develop, too. This means that the cannabinoids in the plant are developing nicely. The final potency of the cannabis will depend on how long it spends in the flowering stage.

When handling the seed, be extremely careful. Avoid touching the taproot as it is fragile and may break. At first, you can transplant the seed into 2-inch pots of soil.

Once the germinated seeds are planted, they will begin growing. A little cannabis plant will sprout from the soil and begin to develop familiar characteristics. During the seedling stage, it will produce two leaves that open outward from the stem to start receiving sunlight. Next, its trademark cannabis leaves will begin to sprout at the top of the plant as it enters its first growth cycle.

2. Seedling Stage: 2-3 Weeks

One option is to buy more seeds from a seed bank. This way, you can keep buying and trying different strains.

The flowering stage is the last stage of growth, and it is the most crucial for you as a cultivator. You can transition plants into the flowering stage by reducing their light exposure. A 12-12 cycle (12 hours of light and 12 hours of darkness) is ideal.

Alternatively, you can place the seeds directly in damp soil to germinate and grow, without having the trouble of moving them. For this method, I would recommend a seed starting mix. These are usually lighter and fluffier than traditional potting soil, which gives your fragile germinating seeds a start on the right foot. We carry Coast of Maine Sprout Island Blend Organic Seed Starter Mix. It has additional perlite that aerates the soil and helps prevent damping off. It also has mycorrhizae, worm castings, lobster meal, hen manure, and kelp to get your plants off to a healthy start.

8. Curing

Stages of Growing Cannabis

Growing Cannabis for the first time can be quite overwhelming. A quick Google search will lead you to hundreds of results with more information than you can ever sift through. There’s so much to learn – lighting, pH, soils, training methods, curing, and so much more. Where does one start?
