Like any other sapling, a cannabis sprout is also fragile and cannot take care of itself. It requires proper maintenance and care to convert into a healthy plant that can be used for multiple purposes. In addition, you need to check the nutrients in the soil, pH of water, and light intensity regularly.
What are Cannabis Seedlings?
Cannabis seedlings are the earliest stage of a cannabis plant’s life cycle. They are the result of a cannabis seed germinating, and begin to grow when the seed splits and a small sprout, or “taproot,” emerges. As the taproot grows deeper into the soil, it begins to branch out and form a small root system. At the same time, a small shoot, or “cotyledon,” emerges from the soil, and begins to grow upward. This small shoot will eventually become the cannabis plant’s first set of leaves.
As the seedling continues to grow, it will develop its first set of true leaves, which are characterized by their “fingered” appearance and jagged edges. These leaves are responsible for photosynthesis, the process by which the plant converts light energy into chemical energy in the form of sugar. As the plant continues to grow and develop, it will produce more sets of leaves, each with more fingers and a larger surface area for photosynthesis.
Cannabis seedlings are very delicate and require special care in order to survive and thrive. They need to be kept in a warm, humid environment with plenty of light. They also require a well-draining, nutrient-rich soil, and should be watered frequently, but not over-watered. Over-watering can lead to root rot, which can be fatal to a seedling.
During the early stages of a cannabis plant’s life cycle, it is important to monitor its growth and development closely. This includes checking for signs of pests or disease, as well as making sure the plant is getting enough light, water, and nutrients. If a seedling is not growing or developing properly, it may be necessary to adjust its environment or provide additional care.
Cannabis Seedling Stage – Description and Change
Let’s go through what happens throughout this stage and learn how to take care of the cannabis seedling.
The four main stages of the growing process are seed germination, cannabis seedling development, vegetative stage, and blooming. The mature cannabis plant grows cotyledon leaves that help it absorb sunlight and grow after the seeds have germinated and have been planted in their growing medium (similar to potting soil).
As the cannabis plant develops, it generates more leaves, which continue to form the distinctive corrugated edges that make the cannabis plant easy to identify.
Each leaf eventually reaches its maturity level and produces its entire complement of leaves (which can be between 5 ridges per leaf to 10). The sapling stage is transitioning from marijuana plants with the most ridged edges on each leaf to cannabis seeds that have germinated.
The sprouting stage of the growth process is crucial; because the marijuana plant is still immature and delicate. Adequate care is required to establish the foundation for a strong mature plant.
Genetics, Mediums, And Containers – Which Ones To Choose?
If you’re wondering which seed strain is optimal for you, well it depends on various factors. These include your experience and skill level as a plant grower, your financial situation, the equipment you use for your plants, and whether you are growing them indoors or outdoors.
Plant the seedling in fertile soil that is well-distributed, glossy, and slightly acidic (pH range of 6.3-6.5). Also, add 20% to 50% of perlite to your medium because it is a great soil aerator and nutrient retention. As you increase the nutrients you want to feed your plants, try to increase the amount of perlite in your soil too, mainly to prevent nutrient blockade and drainage.
Regarding the use of water, you can sprinkle it over stems, but only after the ground has completely dried out to prevent overwatering or under-watering. Cannabis seedlings, especially auto flowering ones, are extremely sensitive to nutrition.
Avoid growing them in hot, nutrient-rich soil, and don’t feed them until they have three to four sets of leaves. Your plantations need a sterile environment to grow, so pay attention to your chosen containers. In the same way, your plant may suffer from both overcrowding and under crowding.
Caring for plants includes selecting the ideal container for your germination seeds. The root system must have adequate room to spread out but not enough space to prevent the roots from absorbing all the water from their surroundings. Ensure that the pot has openings for water to drain to prevent the plant from drowning.
Should You Try Different Germination Techniques?
Of course! Marijuana seeds sprout in four basic conditions:
- Moisture
- Warmth
- Darkness
- Patience
Choose one of the following techniques to ensure your seeds grow into healthy seedlings.
- The paper towel method
- The water glass method
- Seedling beginning kit
How To Plant Cannabis Seedlings?
To start things off, the garden soil should be piled on top of your container. After that, your germinated seeds should be inserted into a hole approximately 12″ deep, with the eraser side down. Next, cover the hole with mud.
You can plant a healthy marijuana seedling in the ground and cover it with dirt. Regarding soil condition, it should be damp but not drenched. Some cannabis growers decide to give additional care to their early plants. Using long wooden kitchen matches is a smart idea.
How To Grow The Cannabis Seedling?
To grow cannabis seedlings, you will need to start with some cannabis seeds. You can either purchase them from a reputable seed bank or obtain them from a mature cannabis plant. Once you have your seeds, you will need to germinate them. This can be done by placing the seeds in a moist paper towel, then placing the towel in a plastic bag and leaving it in a warm, dark place until the seeds germinate, which usually takes about 3-7 days.
Once the seeds have germinated, you will need to transfer them to a growing medium, such as soil or a soilless mix. You can use small pots or seed trays, and make sure to use a light, well-draining growing medium. Water the seedlings gently and make sure to keep the growing medium consistently moist, but not waterlogged.
Place your seedlings in a warm, bright location, but be careful not to place them in direct sunlight, as this can burn the delicate leaves. Seedlings will also benefit from a light source, like grow lights, to supplement natural light.
It’s also important to keep your seedlings’ environment clean and free of pests and diseases. Keep an eye out for any signs of stress, such as yellowing leaves or slow growth, and address the issue promptly.
After a few weeks, your seedlings should be ready to be transplanted into larger containers or even into an outdoor garden. Keep an eye on the weather, making sure that your seedlings have the proper amount of light, water, and nutrients.
Overall, growing cannabis seedlings requires patience and attention to detail, but with the right conditions and care, your seedlings will grow into healthy, mature plants.

The Light Intensity Issue
How much light intensity do cannabis seedlings require? You can use low-wattage HID or LED lights to protect the seedling from damage. If they are overexposed to light, they burn and crinkle. It is also possible for seedlings to grow too thin as a result of a lack of light. You can also use CFL lights with a blue light spectrum and an 18/6 light cycle for the light schedule for the seedling in the first 10-14 days to get the best results. Once they have at least 2-3 nodes and sturdy leaves, you can start to use strong HID or LED lights.
Temperature and Humidity of Cannabis Seedlings
Temperature and humidity are two important factors that can affect the growth and development of cannabis seedlings.
Temperature: Cannabis seedlings prefer temperatures between 70-85°F (21-29°C). If the temperature is too high, it can cause stress and slow down growth. If the temperature is too low, it can cause the seedlings to become weak and vulnerable to disease.
Humidity: Cannabis seedlings prefer humidity levels between 40-60%. High humidity levels can cause the growth of mold and mildew on the seedlings, while low humidity levels can cause the seedlings to become dry and stressed.
During the germination process, humidity levels should be kept high, around 80-90%. Once the seedlings have sprouted, it’s important to gradually lower the humidity levels to the ideal range of 40-60%. This can be achieved by using a humidifier or dehumidifier, or by adjusting the amount of water that you give to the seedlings.
It’s also important to monitor temperature and humidity levels regularly and make adjustments as needed. This will help ensure that your seedlings are growing in the best possible environment and are less likely to suffer from stress or disease.
Watering Cannabis Seedlings
Adding or feeding fertilizers won’t be necessary unless you have chosen a soilless mix. Use a misting bottle to water once or twice daily for the first several days. Your watering schedule will change significantly depending on the temperature and humidity. You can eventually cut back on watering to only once every two to three days. When in doubt, dig your finger into the ground and feel for moisture. Or, when it’s too dry, you can add water. The most frequent reason for early crop loss is overwatering, so try to take care during the cannabis seedling growth process. Make sure to complete this process to get to the mother plant stage and ensure you have healthy cannabis plants. The cultivation journey of a cannabis plant is divided into four distinct stages: the germination period, the seedling phase, the vegetative phase, and the flowering stage.
Growing Cannabis Seedlings Outdoors
When growing marijuana seeds outdoors, the temperature and humidity levels cannot change in the blink of an eye. There are three options for managing the seedling stage if you’re an outside farmer who wants to ensure the best cannabis seedling growth:
Most gardeners choose to save their seedlings from dangers by keeping them indoors for the first two weeks under CFL lights.
For cannabis seedlings to grow perfectly, light is an essential factor. If the temperatures are maintained between 20 and 25 degrees Celsius, you can keep your seedlings outside all day, while at night, you can bring them inside to protect them from the cold.
To protect the plants, increase the humidity levels and modify the temperatures, you can place your seedlings outside for an extended period in a propagator, greenhouse, or polytunnel.
What Are The Problems Faced By Cannabis Seedlings?
Damping off
The conditions created by fungi, such as Botrytis, Pythium, and Fusarium, are known as “damping off.” This static fungus can stay in the soil for a long time. It prefers moist conditions where they can nurture and increase in quantity. Several aspects can induce damping-off, but high humidity and excessive watering are the most common.
Nutrient Issues
Cannabis plants can show signs of the nutritional deficiency by growing faded leaves or stems. Nutrient-rich seeds help your plants survive their early years by giving them energy. When these nutrients run out, you must step in and provide your plants with the nutrition they require to grow and flower properly.
Pests and Insects
Toxins and diseases can eliminate cannabis plants in hours or even minutes. To prevent this, it is mandatory to maintain the surrounding environment of your seedlings at appropriate temperatures and humidity levels. To prevent overwatering and treat common cannabis pests before they become a menace, ensure that you educate yourself on the subject.
Cannabis Seedling Stretching
The marijuana seedlings bend to reach the light source. Place the seedlings 5cm or so below CFLs with a blue spectrum if you don’t want them to grow exceptionally long, flimsy stems. After germination, do not leave your seedlings in the dark for 24 hours. Your seedlings will grow overly long as a result of it.
When to Relocate Marijuana Seedling?
Plants should be nurtured and grown in small containers. These seedlings are too young to absorb as much water as the larger plants; thus, there is a significant probability that they may perish. A marijuana plant seedling must be moved once it is too big to stay in its current location. Your potted seedling should be transplanted at this point because it has grown four leaves or roots intertwined and eroded from the pot. If the plant grows out of the container, you should shift it to another safe location.
