When the root pops out the seed and reaches a length of about 1.5 cm, the seed can be placed in a growing medium and exposed to 18-24 hours light. During this stage, the roots will grow downwards and find their way in the medium. The shell under which the first leaves grow will grow upwards.
The first leaves often feature only one ribbed finger, but when becoming bigger more branches appear and leaves get more “fingers”. Once the strain develops leaves with five “fingers”, we speak about a “seedling”.
Once young seedling has reached the surface, the leaves will push the shell off and small leafs appear to ensure the seedling receives sufficient sunlight.
Once the strain reaches the end of the vegetative stage (the pre-flowering phase) the grower is able to determine the genus of the plant. For the cultivation of weed, the grower must separate male plants from the female plants in order to prevent pollination.
Once the seedling stage has completed the strain will enter the vegetative phase. During this stage the strain needs about 13-24 hours of light each day and will grow considerably. We therefore recommend to repot the plant to a larger pot with healthy, nutritious soil. In that way, the roots have sufficient space which is important for the strain to grow considerably in height and wide.
Note: During the seedling stage, roots are still small so it doesn’t need much water to grow so provide water in a gentle and controlled manner. This will prevent your young seedling from drowning. The roots are located closed to the trunk, so make sure to water your young seedlink close to the trunk. In addition we recommend keeping your culture environment clean as seedlings are fragile and susceptible to diseases and fungi.
The cannabis seed is the starting point. Seeds can be seen as a sleeping organism waiting for water to enter life. This process is called “germination” and takes on average 24 hours up to 168 hours (7 days).
Whether you grow an autoflower or none-autoflower female strain, weed plants go through different stages. This is called the cannabis grow cycle.
The final stage of the cannabis plant is called the flowering phase. A flowering stage lasts on average 6 to 12 weeks. In this stage the strain will develop it’s resinous buds. In nature, cannabis plants will start to bloom when the days get shorter (autumn).
The cannabis grow cycle is devided in 4 stages. The so called weed plant stages. Curious what to expect? Check it out!
Be mindful to increase your watering as the plant develops. When it’s young, your plant will need water close to the stalk, but as it grows the roots will also grow outward, so start watering further away from the stalk so the roots can stretch out and absorb water more efficiently.
To begin growing from a seed,В learn more about germination here. This stage can take anywhere between 5-10 days.
Light cycle: 12 hours of light
- Germination (5-10 days)
- Seedling (2-3 weeks)
- Vegetative (3-16 weeks)
- Flowering (8-11 weeks)
Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.
As the roots develop, you will begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.В В В В В В В В
When your plant becomes a seedling, youвЂ™ll notice it developing more of the traditional cannabis leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (1, 3, 5, 7, etc.). A mature cannabis plant will have between 5-7 blades per leaf, but some plants may have more.
Light cycle: 18 hours of light

ItвЂ™s important to understand the changes a growing cannabis plant undergoes during its life cycle, as each stage of growth requires different care.
