Growing cannabis begins with choosing the right seeds. The quality of cannabis seeds directly affects the health of the plant, the yield, and the potency of the final product. In this article, you will learn everything you need to know before purchasing and growing your own cannabis seeds.
Types of Cannabis Seeds
There are different categories of cannabis seeds, each with specific characteristics:
Regular Seeds: Produced naturally, these seeds can produce both male and female plants. They are ideal for those who want to experiment with breeding and genetic selection.
Feminized Seeds: Genetically modified to produce only female plants, which are responsible for producing cannabinoid-rich flowers.
Autoflowering Seeds: They do not depend on a photoperiod to flower, making them ideal for beginner growers or those who want a quick growth cycle.
How to Recognize Quality Seeds
Not all cannabis seeds are the same. Here are some key aspects to evaluate their quality:
Appearance and Color: High-quality seeds are generally dark brown, with black or gray hues and a smooth or slightly streaked surface. Seeds that are too pale or green are often immature and less likely to germinate successfully.
Size and Shape: Mature seeds are firm and uniform in size. A regular and compact shape indicates good seed development and better germination ability.
Shell Hardness: A good seed has a resistant shell. If it breaks easily under light pressure, it could be immature or of poor quality. On the contrary, a shell that is too hard and impermeable could indicate an old and no longer viable seed.
Flotation Test: Immerse the seeds in a glass of water for a few hours. Quality seeds sink, while poor quality seeds tend to float. However, this test should be used with caution, as prolonged exposure to water can compromise germination.
Seed Age: Fresh seeds are more likely to germinate than old ones. A seed stored for too long may have lost viability, especially if it has not been kept in the right storage conditions.
Origin and Genetics
Genetics is a determining factor in obtaining high-quality plants. Choosing seeds from reputable seed banks ensures genetic stability and better performance in terms of growth and yield. Stable genetics reduce the likelihood of developing plants with undesirable traits, such as irregular growth or low resistance to pests and diseases. Reputable seed banks perform rigorous selection controls to ensure that each seed has the genetic makeup needed to produce healthy, productive plants. In addition, seeds with well-defined genetics allow for predictable flavor and cannabinoid profiles, which is essential for those growing for therapeutic or recreational purposes. Choosing certified varieties also ensures greater uniformity in growth and flowering, making it easier to manage the crop, especially in controlled environments.
Seed Storage
To maintain their viability, seeds must be stored correctly:
Cool and Dry Environment: Humidity and heat can compromise germination.
Airtight Containers: Preferably stored in glass jars or sealed bags.
Away from Light: Direct light can deteriorate the quality of the seeds.
Germination and First Steps
Once you have selected quality seeds, the next step is germination. There are several methods, including:
The paper towel method: The seeds are placed between two layers of damp paper until the first roots appear.
Germination directly in the soil: Suitable for those who want to avoid manipulation and stress to the root.
Using peat cubes or rock wool: Promotes healthy and controlled growth.
Conclusion
Choosing high-quality cannabis seeds is the first step to a successful cultivation. Paying attention to the type, appearance, genetics and storage of seeds can make the difference between a healthy and productive plant and a disappointing harvest. With the right knowledge and a little experience, you can maximize your harvest and obtain excellent quality cannabis.
