Cannabis seedlings: The first step to successful plants

Cannabis seedlings are the beginning of every successful cannabis plant. They represent the sensitive transition phase between seedling and young plant and require special attention. This phase lays the foundation for healthy plants and a rich harvest - whether for indoor or outdoor cultivation.

But what makes for good care? From choosing the right seedlings and optimal lighting to water, nutrients and temperature - there are many factors that are crucial. This page offers you all the important tips and tricks to help your seedlings grow vigorously and develop into strong plants. Whether you're a beginner or an experienced grower, you'll find all the information you need here!

Let's get started!

The right light is crucial for the healthy growth of cannabis seedlings. In the early stages, they need a lot of light - preferably between 16 and 18 hours a day. Here are a few tips:

• Use LED lamps or special plant lamps with a light spectrum of 400-700 nm (PAR range).
• Keep a distance of 20-30 cm between the lamp and the seedlings to avoid burns.
• Use a timer to keep the lighting regular and constant.

With the right light source, your seedlings will grow vigorously and develop stable roots.

One of the most common mistakes when caring for cannabis seedlings is incorrect watering. Here are the most important tips:

• Not too much and not too little: The soil should be slightly moist but not waterlogged.
• Use soft water (pH value of around 6.0) to avoid nutrient blockages.
• It is best to water early in the morning or in the evening when temperatures are lower.

Overwatering can lead to root rot, while dryness inhibits growth, so always ensure a good balance.

In the seedling phase, less is often more when it comes to fertilising . The young plants are sensitive to over-fertilisation. Here are a few tips:

• Start with light doses of nutrients after 2-3 weeks at the earliest.
• Use special nutrient solutions for seedlings with a mild NPK ratio (e.g. 2-1-2).
• Fertilise sparingly - once a week at most.

Over-fertilisation is indicated by yellow or burnt leaves, in which case reduce the amount of fertiliser.

Since the law was amended in 2024 , the legal situation for the private cultivation of cannabis in Germany has been relaxed. Adults are now allowed to legally grow up to three cannabis plants for personal consumption . This also includes growing seedlings, as long as they are intended for personal use.

The purchase of cannabis seeds is also permitted as long as they come from authorised sources and are used for personal cultivation. However, there are still legal grey areas in the commercial trade in cannabis seeds and seedlings, which is why caution is advised.

If you want to buy or grow cannabis seedlings in Germany, you should always check the current legal framework, as regional differences and new regulations may arise. However, if you comply with the legal requirements, nothing stands in the way of legal home cultivation.

Proper care is essential to ensure that your seedlings grow into healthy plants. Pay attention to these basic aspects:

1. Light: 16-18 hours of daily light.
2. Watering: Regularly, but not too much.
3. Temperature: Constant temperatures between 20-25 °C.
4. Fertilising: Only sparingly and with suitable nutrients.
5. Repotting: As soon as the roots fill the pot, it's time for a larger container.

These basics will lay the foundation for successful cannabis cultivation.
