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.

Baby marijuana plants, how to care for them?
How to care for a baby marijuana plant. that big question we always pay less attention to than we should. Everybody knows that the development of people depends mainly on the first three years of life. Well, with our marijuana plants it is exactly the same. The success of our crops depends to a great extent on their care when they are just born.
No, from Delicious Seeds we are not going to discover any miracle. Surely you have already dealt with more than one bud of marijuana, but you can always keep some key that will bring you something new about how to care for baby marijuana plants. Let’s get down to business.
We are continually referring to the care of marijuana seedlings. In other words: we’ve already gone through the germination process, so we’re at that two to three week cannabis seedling period that precedes the vegetative stage.
The first thing to do is to ensure protection
We are talking about plants that are going through their most vulnerable phase. Their roots have not yet taken root, so we are at the point where we have to overprotect them so that they can subsequently impose themselves on external factors and survive on their own.
How does this translate? We have to protect the seedlings indoors. But don’t stop there, to take good care of the plants they need to start tucked in, either by covering them with a plastic material (for example, covering them with a plastic bottle after having broken it in half and pierced it) or with the typical transparent bubble wrap. All this in case you do not have a greenhouse. Relax, there will be time to aerate them with fans.
We already have the principle, now let’s get down to business:
How to water baby marijuana plants
Before talking about specific processes, it will help you more to understand how you have to maintain the soil at this stage, so that you will know better than anyone how to water your newborn marijuana plants. The trick is this: the soil must always be moist. Yes, constantly, and the reason why is very simple.
As we said before, we are focused on our already germinated seeds to generate strong roots to ensure good growth. To achieve this goal, the soil must be loose and well oxygenated so that the roots go through it like a knife through butter. But be careful, if you overdo it and water it we have messed it up because mold appears. This is a wetting process. Yes, you have to use the sprayer at this point.
And now the eternal debate: “mineral water or tap water for watering the pot plant? From Delicious Seeds we are not going to tell you that you have to use tap water at this stage of seedling. Starting with mineral water can also be positive, but please, when you reach the growth stage, water your plants with tap water.
And now it is time to stop for a moment. Before continuing with the explanations and tips on the development of your baby plants, let’s go with a small scheme for you to apply all the actions explained and better understand what we are going to discuss below.
Marijuana plant – Basic care
– Relative humidity close to 80%
– The flower pot cannot be big. We can even use a glass, of course, we must drain it
– The temperature should be around 25º C (in no case lower than 20º C or exceed 30º C)
– Maintain a neutral pH level
– The light has to be very dim
Now we can continue with more specific examples that will end up making you an expert in marijuana seedlings, specifically with information related to the last point we mentioned in the previous highlight.
As time goes by, our plant will need more light, but for the moment it is enough with the typical compact fluorescent bulb. Don’t you see? relax, we will refresh your memory.
You can keep them a hand’s breadth away from your pot plants, and ideally not yet in contact with natural light. In any case, do not let it go beyond the first or last daylight rays.
If you have noticed that the plant is stretching more than normal, it is also due to light reasons. Specifically, because they lack some illumination. These plants will spike because they instinctively go in search of light when they miss it.
It may seem a big problem, but the good thing is that it can be identified quickly and has a solution: All you have to do is sink it. That is to say, to convert what right now is a part of the stem into what in the future will be roots. Easy, isn’t it?
Baby born female marijuana plant, when does the next stage begin?
We say goodbye with a question that not everyone is able to answer. It seems silly, but if we have to know the specific conditions in the different stages of plant growth, why is it important to know exactly when we pass from one stage to another? And if we talk about newborn female marijuana plants, it will be especially important, we are playing a lot!
Be careful, because the rule of the pot seedling can confuse you: this period begins at the moment when the so-called cotyledons (the first two round leaves that are visible) bloom from the seed. On the other hand, this phase ends when the first definitive or true leaf grows. Surely there is no need to explain how to identify the classic digitate shape of the leaves of your plants.
