Grow Weed Starting From Seed
“Don’t judge each day by the harvest you reap but by the seeds that you plant.”
Growing your own cannabis plant starting from seed is a remarkable journey. Understanding the biology of the plant is one thing, but comprehending how a little miracle bean can turn into a gigantic tree producing flowers that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.
Start Growing Weed From Seed
Our favorite thing about growing your own weed 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.
Raising a cannabis 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. And, don’t forget, a Pot for Pot’s Complete Grow Kits take the guesswork out so you always wind up with a splendid harvest!
1) Germinating Your Cannabis Seed
To accelerate germination, soak your seed in a small container with lukewarm water and place it in a dark and warm place (like a kitchen cabinet) for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process on a physical and chemical level. Doing this 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 or put out a taproot. When a seed pops a taproot (often called a tail), it becomes more vulnerable and it is better to plant it before this root emerges.
2) Planting Your Weed Seed
We see best results with seedling pellets that are made of a mix of compressed peat moss and coco husk. To expand, soak it in water for 10 to 15 minutes. Using warmer, lukewarm water, instead of cold water, will speed up the time the pellet takes to fully expand. Once your seedling pellet has absorbed enough water and has expanded to its maximum size, gently squeeze to remove 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 inch 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.

3) Weed Seedling Sprouts
Perhaps the most exciting stage, your plant baby will come above ground in 1-2 weeks, with the average popping up in 5 to 7 days after planting. As your seedling comes above the soil, its shell might take a few days to fall off. It’s best to leave it alone, nature has the job covered. If it does not come above ground after about two weeks, the chance of success is dramatically reduced, and it’s best to try again. Even the best seeds have an 85% germination rate. When your seedling comes above ground, it is going to want to see a direct light source.

4) Lighting for Your Cannabis Seedling
Marijuana seedlings require a medium amount of light — enough to get energy to grow, but not too much light that to get 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, 24 to 30 inches from a grow light is an excellent supplement. Your seedling should not stretch more than 6 inches at most.
5) Watering Your Cannabis Seedling
For cannabis plants young and old, it’s best to use bottled, distilled, or filtered water as these are without chlorine. If using tap water, let it sit for 48 to 96 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 but not soaking wet. Overwatering is just as deadly as drying out!
Damping off happens when the seedling is in too moist of an environment. The young plant’s immune system is not strong enough to ward off a fungus that results in the plant rotting from the bottom of the stem. When this happens, the plant will bend over and die if not treated. To help fight the infection, lightly spray a 0.5% solution of hydrogen peroxide around the affected area. However, the best option is to avoid this by not exposing your seedling to too much moisture.
6) First Cannabis Seedling Leaves & Hardening Off
The first set of leaves to come above ground are called the cotyledons . These little leaves are packed with energy and will grow to about 1/4 in in size before eventually falling off. Your second leaves to emerge will be single blades and will be serrated, looking like regular pot leaves.
They will become several inches in length. During their growth your first actual set of leaves will appear. These are typically three blades. Around this time is when your plant is “hardening off”. You will notice that the stem will start to develop a thicker skin and harden off. As the leaves of the plant get bigger, they can gradually handle more sunlight, so move it into more direct light– the more light the better!
7) Transplanting Cannabis Seedlings
About 10 days after germination, when the baby cannabis plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.
Dig a small hole in your bigger pot for the seedling, sprinkle some rooting booster in the bottom of the hole then carefully plant the whole seedling pellet holding your weed baby.
Now bury so the base of its stalk is level with the topsoil. Give it a watering to set the roots in the ground, then hold off watering until you pick up the pot and it feels light in weight.

8. Separating the Girls from the Boys
At about 4-6 weeks into your plant’s growth , you’ll be able to determine the sex of the plant. You’ll want to separate and dispose of any male plants. This is an important step for growing marijuana because the female plants are more potent and valuable. You also don’t want male plants to compromise the growth of your female plants.
Why Do You Only Want Female Weed Plants?
Only female marijuana plants produce THC buds that are high in potency. You want to make sure your Cannabis plants are all female. If you have a male plant, it can fertilize the other female plants, and they will work to produce seeds instead of flowers and nugs.
It’s essential as a grower to know the difference between a female and a male plant so that you can remove the male plants before they contaminate your crop . Unfortunately, you have a 50/50 chance of getting a male plant when growing a plant from a seed from a nug.
There is a massive market for seeds that will only grow into female plants. But even these seeds are not a 100% guarantee you’re going to get a female plant. To ensure a good crop, you’ll want to germinate and plant many marijuana seeds and then separate the females from the males when the plants begin to show their sexuality.
How to Tell if a Weed Seed is Male or Female
As your plant matures sexually, it will develop between its nodes. Nodes are the area of the plant where the branches connect to the plant’s stalk. The distinguishing characteristics that will help you identify your plant’s gender:
- Male Plants : Small pollen sacs will cluster in the nodes.
- Female Plants : Stigmas will develop in the nodes. The stigmas can catch the pollen of male plants. Stigmas have hair-like veins that will extend from the sacs in the nodes.
- Hermaphrodite Plants : These plants have both the stigmas and pollen sacs in their nodes. These are female plants that develop both sex organs when exposed to a lot of stress.
Once you can identify the sex of your plants, you’ll want to remove the male or hermaphrodite plants because they can negatively affect the harvest of your female plants. That’s why it is crucial to germinate and grow several cannabis plants to this stage to ensure you get at least one healthy female plant.
9) Grow Weed Plant, Grow!
Suddenly, before your very eyes, the plant will transform. She will grow in height and branch out, putting off leaves and a network of branches. It is your job as the grower to meet her needs so that she can reach her full potential. With a good grow kit, this means as much light as possible and lightly watering only when she is thirsty.
This is considered your marijuana plant’s vegetive stage. The goal in this stage is to keep her healthy and allow the plant to grow as big and strong as possible so that she can hold many, many flowers.

Have you recently decided to germinate your own cannabis seeds? It is a very exciting and rewarding process, only if you know the right way to do it. For that, we have come with a complete guide that will help you germinate cannabis seeds in the best way possible.
What exactly is Germination?
Germination is the very first stage of any plant growth. It is when the seed “realizes” that it is in a fertile environment and can start breaking out of its shell. A seedling will break through the shell, resulting in the growth of roots. The fertile environment helps the plant grow and feed off the light, water and nutrients in the environment. In the cannabis world, germination is a very important process. It is very important for the seed to pop out properly. There are different things that cultivators do to ensure that the seed germinates successfully.
How to Germinate Cannabis Seeds
There are different methods that cultivators use to germinate their cannabis seeds. Some use the old school method and germinate their seeds in the soil, while there are some people who germinate them in water. Lastly, you can also find people who germinate their seeds in paper towels. The way of cultivation depends on the cultivator. Let us take a closer look at each of these methods.
Germination of Cannabis Seeds in Soil
Soil is the most natural method to germinate your cannabis seeds. The soil is the perfect environment for the germination of cannabis seeds as the soils protects the weak roots from being damaged. However, there are things that you must take care of. For instance, it is very important to use the right type of soil.

You can go for potting soil that is only lightly fertilized or you can also go for a seed starter that has a pH level 6 or slightly more acidic. The acidity in the soil is the optimal environment for the growth of the seed. Be careful, excess of everything is bad, and “hot soils” that are very rich in nutrients aren’t suitable for germination and seedlings – leave this type of medium for mature plants.
Germination of Cannabis Seeds in Water
If you want your plant to grow faster, germinating your seeds in water will probably be the best way forward. However, even though it is faster, there are things that you need to be careful with. You will have to make sure that the environment is of the optimal condition. Usually, to germinate, cannabis seeds need only a total of 24 to 48 hours. However, cultivators can keep their seeds soaked for a week. This method is faster than the soil method as it provides more moisture. Moisture is a key component in growing the seeds. The hard shell cannot withstand the moisture and it will become easier for the root to break through.
Germination of Cannabis Seeds in Paper Towels
Paper towels are a fairly new way for cultivators to germinate their seeds. Cultivators use damp paper towels or cotton pads to give the seed the moisture it needs. The seeds are placed in between two dampened paper towels and then enclosed between two plates. This helps keep the moisture in seeds need to be stored inside, under room temperature.
The germination process in this method takes up to 5 days to happen. The seeds will start sprouting in the paper towels and once the roots grow up to 5 millimeters in length, you can plant them. However, you must be very careful when planting them. They can easily break, as the roots are very fragile. It is possible for the roots to be tangled in the paper towels and break off. This is why it is best if you are extra gentle when handling them – the best way is to use a pair of sterile tweezers.
These are three ways you can germinate your cannabis seeds. The question remains as to which of these ways is the best. That depends solely on the cultivator. They need to decide what method works best for them and is the easiest to carry out. As our experience shows, more and more growers tend to use paper towel method, as it is simple, keeps the seed away from light, and usually results in quick germination. Also remember, that it is best to germinate the seeds and keep the young seedlings indoors as you can control the environment.
