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.
If you need to determine the sex of your plants (to discard the males), they will start showing sex organs a few weeks into the veg stage. It’s imperative to separate males so they don’t pollinate the females.
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.
What are a weed plant’s growth stages?
The first marijuana plant stage begins with the seed. A cannabis seed should feel hard and dry, and be light- to dark-brown in color. An undeveloped seed is generally squishy and green or white in color and likely won’t germinate.
The Spring Equinox is a good reminder that it’s time to kick off the outdoor growing process and start germinating your seeds.
Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
Seedling stage length: 2-3 weeks
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.
However, some growers prefer to use cloning. All you need to do is cut a branch of at least four inches from the most productive plant in your crop and plant it into a rooting solution. The plant that grows will be genetically identical, making the growing process predictable and easy. It does mean that you get the same every time, though, which can get a bit repetitive.
During the vegetative stage, the general rule is to keep the temperature between 68 and 77˚f, and the humidity between 50% and 70%. Once again, nitrogen is the essential nutrient, but you can also increase levels of other key nutrients in the feed. The plants will need 16-24 hours of sunlight.
6. Pruning Your Marijuana
And then there are other states, in which recreational marijuana is legal. In fact, Colorado, Alaska, Massachusetts, and Maine make no distinction between medicinal grows and legal grows. In other words, any adult of legal age can cultivate marijuana in their home, but there are limits as to how many plants you can have.
There are a few ways to germinate a cannabis seed, but most people use the paper towel method. It’s super easy and won’t take long at all. Here’s what to do:
Marijuana legalization is spreading. Medicinal marijuana use is now legal in over half of states, allowing patients access to the herb once they have a recommendation from a licensed physician. However, it’s no secret that weed is expensive.
Final Thoughts: Growing Your Cannabis Through 7 Stages
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!
Furthermore, the end of the vegetative stage provides a vital opportunity to look for males in your crop. As plants leave this stage, the females will start developing two white pistils, where males will grow pollen sacs. If you see these sacs, remove the plant from the vicinity before it pollinates the females and ruins your harvest.
The flowering stage is the last stage of the Cannabis plant life cycle. This is the time when your plant will stop putting as much energy into leaf growth and will instead focus that energy on creating the flowers (buds), which are used for medicinal and recreational purposes.
2. Seedling Stage
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?
Stages of Growing Cannabis
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.
During the first week of curing, you will want to “burp” your jars. This means you should open the containers once or twice a day for a couple minutes to allows moisture to escape and replenish the oxygen inside the container. After the first week, you only need to burp containers once every few days.
Starting with gaining a general understanding of the stages of growing Cannabis is a great place to begin before you try growing for the first time. It will help you have a decent idea of what to expect along the way.
How long Cannabis takes to grow can vary based on the variety of the plant and conditions it is grown in. On average, from seed to harvest, it takes anywhere from 10-32 weeks (about 3-8 months). It’s a quicker process if you start with a clone (rooted cutting) or an autoflower seed. The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.
