Essential Steps After Germinating Cannabis Seeds

Prepare the Growing Space

Importance of Lighting

Light is one of the most important factors for seedling development. Make sure they receive between 16 and 18 hours of light per day in this initial stage. If growing indoors, use LED or CFL lights that emit little heat to avoid damage.

Adjusting Temperature and Humidity

Maintain a constant temperature between 20 and 25°C and a relative humidity of 60-70%. These conditions promote initial growth and prevent stress in seedlings.

Transplant Germinated Seeds Carefully

How to Choose the Ideal Substrate

Select a well-aerated and well-draining substrate that allows root development. A mix of peat, perlite, and coconut fiber is an excellent option for this initial stage.

Steps for Transplanting Without Damaging the Roots

• Prepare a small pot with the appropriate substrate.
• Make a shallow hole (approximately 1-2 cm deep).
• Place the germinated seed with the radicle pointing downward.
• Gently cover it with substrate without compacting it too much.
• Lightly water to moisten the substrate.

Initial Watering: How to Do It Correctly?

Watering Frequency for Seedlings

Water only when the substrate feels slightly dry to the touch. Excess water can cause root rot.

Recommended Water Amount

Use small amounts of water to avoid saturating the substrate. A spray bottle is ideal for maintaining uniform moisture.

How to Prepare the Substrate for Transplanting Germinated Seeds

Selecting Suitable Pots

Recommended Size and Material

For newly germinated seedlings, use small pots (0.5 to 1 liter). This facilitates humidity control and root development. Choose plastic or fabric pots with good drainage.

Creating the Hole for the Seed

Depth and Technique to Avoid Damage

The hole should be deep enough to cover the seed without exposing the radicle. Use your fingers or a clean tool to avoid damaging the fragile roots.

Adding Nutrients: Is It Necessary at This Stage?

At this early stage, adding strong fertilizers is unnecessary. The substrate usually contains enough nutrients for the first few weeks. If you decide to use fertilizers, opt for those designed for seedlings with low nitrogen levels.

Basic Care for Seedlings After Transplanting

Importance of Light: How Much Do Seedlings Need?

Make sure seedlings receive direct or artificial light for at least 16 hours a day. Place lights at a distance of 30-40 cm to avoid burns.

Controlling Temperature and Humidity in the First Weeks

Constantly monitor environmental conditions. Excess heat or humidity can weaken seedlings, making them susceptible to disease.

Detecting and Preventing Pests in Young Seedlings

Regularly inspect leaves and stems for signs of pests such as mites or whiteflies. Use organic insecticides or homemade solutions to control any infestation.

Additional Tips for Post-Germination Care

How to Stimulate Healthy Growth?

Provide a constant airflow using fans to strengthen stems and prevent mold growth. This also helps maintain a uniform temperature.

Using Fertilizers: When and How to Start?

Start applying light fertilizers once seedlings develop their second set of true leaves. Use a diluted solution to avoid damage.

When to Transplant to a Larger Pot?

When the roots begin to emerge from the drainage holes, it is time to transplant to a larger pot (3-5 liters). This process should be done carefully to avoid damaging the roots.

Frequently Asked Questions About What to Do After Germinating Cannabis Seeds

What to Do If the Seedling Looks Weak After Transplanting?

If the seedling appears tilted or with drooping leaves, check the lighting, watering, and humidity conditions. Provide support using a small stake or tutor.

Is It Better to Transplant Directly into the Final Pot?

This depends on the type of seed. Autoflowering seeds should be planted directly in the final pot, while feminized seeds can be transplanted multiple times.

How Long Before the Vegetative Stage Begins?

Generally, the vegetative stage begins between the second and fourth week, depending on the seed variety and growing conditions.

Common Mistakes After Germination and How to Avoid Them

Overwatering or Underwatering

Excess water can cause root rot, while lack of water can dehydrate seedlings. Maintain a balance by observing the condition of the substrate.

Not Providing the Necessary Light Conditions

Lack of light can cause seedlings to grow too tall and weak. Ensure you provide the appropriate amount and quality of light.

Mishandling Roots During Transplanting

Handling roots too roughly can seriously damage them. Use clean tools and work carefully to minimize plant stress.
