Congratulations! The seed is ready to start growing.
A good trick is to look closely at the pistils. When they begin to turn brown, and the leaves start to yellow, now is the time to harvest. Generally, experts say you should harvest the plants when 70-90% of the pistils have browned. If the pistils are entirely brown, the marijuana may be ‘overripe’ – it won’t taste good, and its effects will be less pleasant.
3. Vegetative Stage: 3-8 Weeks
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.
6. Pruning Your Marijuana
At this point, you should keep the temperature somewhere between 68 and 77˚F, with the humidity at around 50%. You can stop giving the plant nitrogen now, but up the intake of potassium and phosphorus.
Once your seed has germinated, it’s now time to move the germinated seed from its paper towel to a growing medium. If you started them in a seed starting mix, you will want to move them from the seed tray to a larger pot with a high-quality potting mix, such as the Coast of Maine Stonington Blend Grower’s Mix. This is a super soil, that works especially well for growing Cannabis. It contains mycorrhizae, kelp, alfalfa meal, fish bone meal, worm castings, perlite, manure, peat, coir, and lobster compost that feed your plant throughout the growing cycle, with no need to use additional nutrients.
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
Cannabis, weed, marijuana, kush, ganja – whatever you want to call it, it’s now legal to own and grow in the state of Virginia. So what does this mean for those interested in growing it?
Plants are considered seedlings for about 2-3 weeks after germination. During this time, the plant should be moved to a spot with direct sun, if growing outdoors. If growing indoors, set your grow lights to run for 16 hours a day.
After your plant has dried, it’s time to trim! Trimming makes your fingers very sticky, so wear gloves if this is something you want to avoid. Simply trim off the larger leaves and stems. You can leave smaller sugar leaves if you’d like, as these still contain a good amount of cannabinoids and terpenes that provide the medicinal properties of Cannabis. It’s all personal preference of exactly how much you trim off. And you can save all the trimmings to make edibles, tinctures, salves, and more.
3. Vegetative Stage
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.
