How can I tell if my bag seeds are healthy?

Cannabis seeds are the foundation for a successful and bountiful harvest. Ensuring that you have healthy seeds is crucial to the growth and development of your cannabis plants. In this article, we will discuss the various ways you can determine if your cannabis seeds are healthy and how to store them for optimal germination. We will also answer five frequently asked questions about cannabis seed health.

Identifying Healthy Cannabis Seeds​

Color and Appearance​

Healthy cannabis seeds are usually dark brown or black with a sleek, glossy finish. They may also have dark, mottled patterns on their surface. Avoid pale, green, or white seeds, as these are immature and unlikely to germinate.

Size and Shape​

Mature cannabis seeds are generally larger, rounder, and symmetrical in shape. Smaller or irregularly shaped seeds may not be fully developed and could result in weak, unhealthy plants.

Hardness and Durability​

A healthy cannabis seed should have a hard outer shell that can withstand gentle pressure without cracking. If a seed is easily crushed or deformed, it is unlikely to be viable.

Proper Storage for Cannabis Seeds​


Cannabis seeds should be stored in a cool, dark place, ideally between 40-45°F (4-7°C). Avoid exposing seeds to extreme temperature fluctuations or high heat, as this can damage their viability.


Maintain a relative humidity of 20-30% for optimal seed storage. Excessive moisture can lead to mold growth, while overly dry conditions can cause seeds to lose their ability to germinate.


Cannabis seeds should be stored away from direct sunlight or bright artificial light. Exposure to light can trigger germination prematurely, leading to a weakened plant.

5 Frequently Asked Questions About Cannabis Seed Health​

1. How long can I store cannabis seeds?​

If stored properly, cannabis seeds can remain viable for several years. However, germination rates may decrease over time, so it is best to use seeds within 1-2 years for optimal results.

2. Can I improve the germination rate of old or low-quality seeds?​

While there are no guarantees, some methods may improve the germination rate of older or lower-quality seeds. These include soaking the seeds in water for 12-24 hours, using a seed germination booster, or employing the "paper towel method" for germination.

3. How can I test the viability of cannabis seeds before planting?​

You can perform a simple "squeeze test" to check the viability of your seeds. Gently apply pressure to the seed between your thumb and index finger. If the seed remains intact and does not crack, it is likely viable.

4. How long does it take for cannabis seeds to germinate?​

Cannabis seeds typically take 3-7 days to germinate, depending on factors such as seed age, quality, and environmental conditions.

5. What should I do if my cannabis seeds don't germinate?​

If your seeds fail to germinate, consider the following factors: seed quality, storage conditions, and germination methods. Ensure that you are using high-quality seeds, storing them properly, and employing effective germination techniques. If seeds still fail to germinate, contact the seed supplier to discuss potential issues or request a replacement.

In conclusion, healthy cannabis seeds are essential for a productive and successful grow. By paying attention to the color, appearance, size, shape, and hardness of your seeds, you can ensure that you are starting with the best possible foundation. Proper storage and germination techniques will further increase your chances of a bountiful harvest.
