Tips For Growing Marijuana In The Seedling Stage

The team from Crop King Seeds gives us this guide to growing marijuana during the vulnerable seedling stage.

Your Cannabis plants will never be as vulnerable as they are in their seedling stage. Seedlings are prone to damage and disease than they are at any other stage in the plant’s life cycle. That’s why taking special care at this point in the growing process is a must.

While these warnings may sound dire, the truth is that while caring for cannabis seedlings is extremely important, it isn’t terribly difficult to do if you know what to look out for. This article is meant to serve as a beginner’s guide to caring for seedling cannabis.

These three basic steps should be enough to get you started:

1. Pots and Mediums for Cannabis

It’s important to choose the right container and growing medium for your seedling plants. Soil has always been a popular choice to germinate marijuana because it’s the simplest and most familiar medium.

Before you choose, you also have to take into account whether you’re using autoflowering seeds, or feminized seeds:

A Pot For Autoflowering Cannabis Seeds

When you choose to go with autoflowering seeds, you need whatever pot you choose to be able to accommodate the full grown plant. By choosing the right pot for your autoflowering seeds at this point, you will begin to see substantial growth within the first three weeks of your seedlings’ lives.

Regardless of the strain you use or what growing method you choose, the size of your pot should be between 1-5 liters. In this case, size does matter as the pot has a huge impact on the size of your weed plant, how often you need to water it, and most of all, its overall yield. We suggest choosing airpots, since they will offer the roots of your seedlings more oxygen than a standard pot might. The result of more oxygen is a healthier plant that will producer more buds.

Pots For Feminized Cannabis Seeds

Starting pots for feminized seeds to not need to be full sized, as it is extremely easy to transplant feminized seedlings from pot to pot.

2. Environmental Conditions for Growing Marijuana

Cannabis seedlings are delicate when it comes to their needs for growth. The environment they’re growing in should be fairly specific:

Cannabis Grow Room Lighting

Though seedlings are just small cannabis plants, they already need a specific type of light in order to flourish. The good news is that they don’t need the same intensity of light that their fully grown counterparts do, and a simple CFL light in the blue light spectrum should do just fine.

Cannabis Watering

Watering the seedlings is where many first time growers experience their first real issues. It’s easy to over-water, so that’s something that needs to be very closely monitored during the seedlings stage.

3. Nutrients for a Cannabis Seedling

A cannabis plant will not grow to produce a potent bud without the help of right set of nutrients. Seedlings, however, do quite well in producing their own nutrients without interference. However, as your plant grows, it will slowly begin to require more than simple soil can provide.

Though you may be tempted to feed your seedlings anyway, Overfeeding is a pitfall that can easily end your plant’s lift prematurely. Some well meaning nutrient supplements could easily poison the seedling.

Crop King Seeds provides a large selection of both feminized and autoflowing seeds.

How to care for your cannabis seedling

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.

The seedling stage can be an especially vulnerable time in the growing process. The cannabis seedling is in need of a lot of TLC to grow into a healthy cannabis plant.

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?

Let’s take a deep dive into how to care for your baby marijuana plant so you know exactly how to take care of your growing seedling and make sure it grows into a healthy, mature cannabis plant.

What happens during the seedling stage?

Before we jump into how to care for your cannabis seedling, let’s quickly cover what happens during this grow stage.

The growing process has four key stages: the seed germination stage, the seedling stage, the vegetative stage, and the flowering stage. Once the cannabis seeds germinate and are placed into their growing medium (like a potting mix), they start to root into the soil as the stem grows upward, sprouting two cotyledon leaves, which help the plant absorb light and continue to grow.

As the plant grows, it starts to produce more fan leaves — and those leaves continue to develop the ridged edges that you’ll immediately recognize as the marijuana plant. As more leaves grow, more ridged edges develop until finally, the plant is fully grown with each leaf reaching its maximum number of edges (which can be anywhere from 5 ridges per leaf to upwards of 10).

This stage — moving from germinated cannabis seeds to cannabis plants with the maximum number of ridged edges per leaf — is the seedling stage.

The seedling stage is an incredibly important part of the growing process; because the cannabis plant is still young and fragile, proper care is essential if you want to lay the foundation for a healthy mature plant.

But what does that care look like? What are the key things to know when it comes to how to take care of marijuana seedlings?

Choose the right container

Your cannabis seedling needs space to grow. But too much space and too little space can both create problems for your plant.

If you try to grow your seedling in a container that’s too large, the root system won’t be able to absorb all the water in the soil. If you start growing your seedling in a container that’s too small, the roots won’t have space to extend and will start to wrap around themselves, which will also impact their ability to absorb water.

Choosing the right pot is an essential part of caring for your growing plant. You need a pot that’s going to give the root system space to grow, but not so much space that the roots won’t be able to absorb all the water in the soil. You should also make sure the pot has drainage holes to get rid of any excess water that could overwhelm the plant.

Be mindful of how much you water your cannabis seedlings

When it comes to watering your seedlings, you want to give them the water they need to thrive. But too much water can actually have a negative impact on the growth process, so it’s important to be mindful of how much you water your seedlings.

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.

If you’re not sure how much water is too much water, keep in mind that you want the growing medium (AKA the soil) to be damp and moist — not soaked and oversaturated.

Know the signs of nutrient deficiencies

A nutrient deficiency can cause serious issues for your growing plant, so part of proper care is knowing how to spot the signs of a nutrient deficiency.

Nutrient deficiencies can come from a variety of places. “Hot” potting mixes that contain too many nutrients could cause nutrient toxicity. On the other end of the spectrum, under-watering can cause a deficiency in the key nutrients your plant needs to grow.

Some red flags that signal your seedling may have a deficiency in nutrients (or nutrient toxicity) include:

  • Dark coloring (cannabis seedlings should be a vibrant shade of green)
  • A burned appearance on the tip of the leaves
  • A curling on the tip of the leaves
  • Yellowing leaves

If you notice any of these issues with your plant, it could be the result of too many or too few nutrients. You’ll need to adjust your growing strategy to support your plant’s health.

Choose the right lighting

Like any plant, seedlings need light in order to grow and thrive. But not all light is created equal. If you want your seedling to grow into a healthy cannabis plant, you need to expose it to the right type of light.

If you’re growing your seedlings outdoors, they’ll need to be exposed to as much sunlight as possible. Keep them in the sun from sunrise to sunset; the more sunlight exposure they get, the better.

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.

Growing your seedlings indoors with artificial light gives you more control over the process, making it easier to ensure your plants are getting enough light each day. If you’re growing with artificial lights (compact fluorescent lights that emit cooler, blue spectrum light are especially effective), aim to give your plants 18 hours on and six hours off each day.

Keep your environment at the right temperature and humidity

Environmental conditions are essential to growing healthy cannabis seedlings, and some of the most important conditions to control are temperature and humidity.

The temperature in your grow environment shouldn’t exceed 80 degrees Fahrenheit, otherwise the seedlings may grow too tall. (You should also plan on lowering the temperature at night to about 70 degrees Fahrenheit.)

You should also aim to keep humidity in the grow environment at a higher level, typically around 70 percent. That way, the plants can absorb moisture from the environment to develop stronger roots without getting weighed down by over-watering.

Get out there and grow your seedling into a full-grown marijuana plant

Watching your cannabis seeds transform into seedlings is an exciting part of the growth process. And now that you know how to care for your cannabis seedling, you should have everything you need to transform your seedling into a mature, healthy, and flowering cannabis plant.
