Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.
When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan 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 (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.
What are a weed plant’s growth stages?
The vegetative stage of cannabis is where the plant’s growth truly takes off. At this point, you’ve transplanted your plant into a larger pot and the roots and foliage are developing rapidly. This is also the time to begin topping or training your plants.
The first marijuana plant stage begins with the seed. A cannabis seed should feel hard and dry, and be light- to dark-brown in color. An undeveloped seed is generally squishy and green or white in color and likely won’t germinate.
Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
But what does that TLC look like? What steps do you need to take to support your cannabis seedlings through the seedling stage and as they grow into mature marijuana plants?
But growing your seedlings outdoors can be tricky. Because you can’t control sunlight, there’s no way to ensure your cannabis seedlings are getting the light they need to grow properly. A cloudy day can prevent your seedlings from getting enough light and throw off your entire growth process.
The root system of a seedling isn’t elaborate; the roots are small and don’t need much water to grow. Misting the plants with water once or twice a day should be plenty to give them the hydration they need to grow.
When you’re growing cannabis, you want to keep your plants strong and healthy through every stage of the growing process — and that includes the seedling stage.
Some red flags that signal your seedling may have a deficiency in nutrients (or nutrient toxicity) include:
The first stage is as quick as it is beautiful: right after germination, the embryo emerges through the seed coat and turns into a tiny root when sowed. As it receives nourishment and moisture, the little seedlings start to appear. In botany, this stage is known as the stage of development, and it extends from the germination and subsequent emergence of the cotyledon (two round-shaped primary leaves) to the unfurling of the first true leaves (a set of jagged leaflets). These plants are still rather fragile and spindly, and many inexperienced growers fail to properly analyze the needs of the newborn seedlings, sometimes even causing them to die.
Plants should be well rooted. That’s the most important thing. If you succeed, you’ll have come a long way. During the first two weeks, you’ll have to make sure roots are developed enough to absorb all the nutrients cannabis plants need. Now that plants are so young, the use of chemicals is not recommended for any little mistake could be fatal. That’s why ecological systems are preferred. Apart from less aggressive, they’re far more sustainable.
Searching for light: what to bear in mind
The presence of these harmful organisms, who love wet and warm environments, prevents nutrients from moving around and so roots from absorbing them. The best way to fight them is prevention. Keep a watchful eye on the moisture levels and avoid overwatering your plants. If you see the surface of the substrate is still damp, don’t add any water. Wait until it’s dry.
Growing weed is not only interesting but good fun too. Not everything is as rosy, though, for it’s also a bumpy ride full of twists and turns. A good start is always key for a good finish, so having a solid understanding of the ins and outs of marijuana seedlings can be the difference between success and frustration. By controlling their size, boosting the growth of their roots and providing them with the right kind of nutrients, we’ll lay the foundations for stronger plants and better yields later on.
If the coloring fails to disappear, and more and more leaves with fragile stems keep emerging, the reason could be excess nitrogen, which will lead to lower yields. The best solution is to thoroughly cleanse the root zone by overwatering your plants.
