If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
Time to germinate
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
For young plants, it’s best to use bottled water as it has no chlorine added. If using tap water, let it sit for 24 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp. Overwatering is just as deadly as drying out.
Raising a seedling, however, requires some patience, gentle hands, and a smidgen of luck. Thankfully pot seeds are remarkably vigorous because they are what’s called endosperm seeds, which means they have almost pre-formed cotyledon leaves before you even add water. Below is a brief guide on the techniques we have found yield the most success when starting seeds and raising your seedling to a healthy plant ready for transplanting.
Our favorite thing about starting from a seed, rather than a clone, is that you get to see the full life cycle and enjoy a plant that is unique, just like you. An entirely new genetic makeup will enter the world for the first time, and if you’re lucky, something remarkable might be born.
4) Lighting for your seedling
We like to use seedling pellets that are made of a mix of compressed peat moss and coco husk. To expand, soak it in water for 10 minutes. Once your seedling pellet has absorbed enough water and has expanded to its maximum size, drain off any excess water. The growing medium should be like a damp sponge that would not leave streaks on the table. Dig a small hole about 1/4 in deep for your seed. Use a spoon to lift the seed out of its bath. If it has popped out a taproot be careful not to damage it. Gently place the seed into the hole and lightly cover it with dirt from the pellet. Now that you have started the germination process, your seedling will come above ground within two weeks. The older the seed, the longer it takes for it to germinate.
To accelerate germination, you are going to want to soak your seed in a small container with lukewarm water and place it in a dark and warm place for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process. Doing this also helps to loosen the shell as it becomes a little softer making it easier for the embryo to crack it open. When your seed sinks to the bottom it is ready to be planted, and sometimes the seed will pop out a small taproot. A seed can still be planted though if it does not sink.
Seedlings require a medium amount of light in which it has enough to grow but not too much light that it gets burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 18 in away from a growing light works excellently. Your seedling should not stretch more than 6 in at most. We’ll cover lighting in more depth in a later blog.
Starting from seed is a remarkable journey. Understanding the biology is one thing, but comprehending how a little miracle bean can turn into a gigantic tree that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.
After a few days to roughly a week, the seed will begin to spread out its roots and start to shoot up towards the sun. You’ll likely even see the very beginnings of tiny marijuana leaves!
This gravel helps provide a good base for the soil, as well as providing drainage.
Well, worry not, those are just marijuana seeds . It seems pretty obvious if you think about it – marijuana is a plant, and plants have seeds. Simple, right?
Some Notes of Warning
Contrary to what most people think, what you’re smoking isn’t actually the rolled up or dried leaves of the Cannabis Sativa plant. You’re actually smoking small flower buds.
It does seem rather odd, considering the prolific nature of the marijuana leaf in stoner culture – we even have images stretching back thousands of years, documented in ancient texts, of the marijuana leaf.
If you’re planning to grow cannabis indoors , away from prying eyes, and then make sure you have an adequate UV light setup to make sure it gets enough sunlight. Don’t forget to make sure the room where it’s kept is hot and humid enough!
Enjoy harvesting your new marijuana and keep an eye out for new seeds in your freshly harvested buds.
Given some time, you might find yourselves planting the great-granddaughter of your first seed!
