marijuana seed growth stages

There are a number of changes to consider once plants go from the vegetative stage to the flowering stage:

If you’re growing weed indoors, you can grow whenever you like. Keep in mind that the outside environment will affect your grow space—you may need to add heaters in the winter or fans and ACs in the summer. Other than that, you can start seeds whenever you like and flip them into flower whenever you like, depending on how big you want the plants.

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.

Flowering stage

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.

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.

The vegetative stage of cannabis is where the plant’s growth truly takes off. At this point, you’ve transplanted your plant into a larger pot and the roots and foliage are developing rapidly. This is also the time to begin topping or training your plants.

The flowering stage is the final stage of growth for a cannabis plant. This is when plants start to develop resinous buds and your hard work will be realized. Most strains flower in 8-9 weeks, but some can take even longer, especially some sativas.

Growers want to use female plants because these are the only ones that produce a massive quantity of trichomes. In case you didn’t know, trichomes are the white crystals packed full of cannabinoids like CBD and THC. Male plants are virtually useless, but they could end up contaminating your crop if you keep them around.

Invest in some delicate scissors – not the same ones you used to cut the plants down. It’s also a good idea to grab a chair because you could be here a while! Wet pruning will also require gardening gloves because the plants will be sticky.

2. Seedling Stage: 2-3 Weeks

If you want to try your hand at cannabis growing, check the laws in your state beforehand. Then, it’s vital to read up on all this related to cultivating cannabis so you can have a successful grow. In this article, we look at the seven steps of cannabis growing and harvesting to help you get the most out of your grow op.

Using your own home-grown Mary Jane can be very rewarding. If you’re a cannabis user with a green thumb, then we recommend giving it a go at least once. You never know, you might find your new favorite hobby! Once you get the hang of things, you can start growing more challenging and exciting strains.

Vertical growth will take place now, with plants growing taller. We have heard of people’s plants gaining 2 inches in height in just 24 hours!

Another sign that your buds are maturing is when the pistils of the flowers change colour. Pistils are small-hair like structures that grow out of the calyxes, and are the reproductive organs of the female cannabis plant. They are the site where pollination occurs—if male pollen were allowed to land there. Pistils appear bright white during the early stage of the grow cycle, and eventually shift to an orange-brown colour.

The way these differ from photoperiod plants is written in the name. Regardless of whether you feel the plant is ready, it’ll start flowering at a certain time depending on the strain’s genetic programming. In one sense, these plants are easier for novice growers because there’s less to think about in regards to light coverage and cycle adjustment. On the other hand, due to the limited vegetation time, you have fewer opportunities for mistakes. This isn’t ideal for first-timers, but the fact that it only takes two months from germination to harvest is definitely appealing. Autos tend to produce lower, milder yields than their photoperiod counterparts, but modern advances are bridging the gap.

Now that harvesting and trimming are complete, it’s time to cure your flowers. Curing is an essential process that removes the last of the residual water from the buds, minimising the chance of mould and greatly prolonging shelf life. Curing also enhances the taste and quality of the smoke, making for a smooth and potent experience.

HARVESTING

Of course Autoflowering strains don’t follow the rules due to their Ruderalis genetics, so they will begin to bloom in about a month post-germination. Auto’s prefer to stay in 18+ hours of light for flowering and will be more productive on a light-dark cycle that would inhibit photoperiod strains from blooming at all.

This is the point where it starts to look more like a cannabis plant. There will be one ridged blade per leaf at first, but the blades will get closer to their typical 5–7-finger stage by the end of this period. Until they get the full 5–7 blades, though, the plants are considered seedlings. Along with the increasing blade count, a vibrant green colour is another mark of a healthy plant. To keep them healthy, the two main things to keep an eye on are water and cleanliness. Seedlings are still fragile, so only light watering is necessary. Cleanliness is equally vital due to their disease and mould vulnerability. The perfect home for cannabis seedlings is a propagator, ideally with 70% RH and temps 20-25°C, under either white CFL lights or LED’s.

One of the best ways to truly tell if your flowers are ready for harvest is by getting up close and personal with a magnifying device. This visual advantage will enable you to detect minor changes that wouldn’t be noticeable to the naked eye. Some growers choose to use a jeweler’s loupe, which is essentially a pocket-sized magnifying glass encased in a piece of metal. Others choose to use devices such as digital microscopes, which provide greater detail.

Growing cannabis comes with a lot of uncertainties. That said, cannabis cultivation itself can be broken down into five distinct stages, regardless of which seeds you’ve selected.
