Storing Cannabis Seeds | Seed to Shelf: Best Practices

Storing cannabis seeds the proper way from the beggining!

In the world of cannabis breeding, every stage in the process, from seed to shelf, is essential for preserving the effectiveness and quality of the end product. Though cultivation and harvesting get much of the limelight, seed storage is also an important factor that should not be underestimated. In this guide we will examine the most effective ways of storing marijuana seeds for optimal viability and quality and thereby answer the question of how to store cannabis effectively.


Understanding the Importance of Seed Storage

Cannabis seeds are the very start of every productive harvest. Like any other plant, the cannabis seed contains all the information needed to grow into a strong and healthy plant. Nevertheless, unlike many other plant seeds, cannabis seeds are also rich in oils and nutrients that can lose their quality if not stored properly.

Adequate storage is necessary to not only retain the germination capacity of seeds but also safeguard their genetic composition. This suggests that stored seeds will still grow into plants with the same desired traits and characters, guaranteeing uniformity and quality from generation to generation.


Factors Affecting Seed Viability

Several elements can cause the loss of germination potential of cannabis seeds during storage. Among them are:

Temperature: To avoid any overheating and temperature changes that may degrade the viability, cannabis seeds should be kept in a cool, dark place.

Humidity: High levels of moisture will encourage the growth of molds and mildew while too dry conditions will make the seeds brittle and lose their viability. The optimal humidity levels should be maintained for long-term storage of seeds.

Light: Exposure to light, especially UV light, will result in the degradation of the oils and nutrients in cannabis seeds. Seeds should be stored in opaque containers to avoid light exposure.

Airflow: Adequate airflow is essential to avoid excess moisture buildup and also for maintaining an even environment for seed storage.


Best Practices for Storing Cannabis Seeds

Now that we are aware of the role played by proper seed storage and of the factors that can influence the viability of seeds, let’s look at some best practices:

Choose the Right Container: Cannabis seeds should be kept in airtight containers to guard against moisture, light and oxygen. Glass jars or plastic containers with tightly-fitting lids are the best choices for this.

Keep it Cool: Cannabis seeds should be stored in a cool and dark place, like the fridge or freezer. Although it is necessary to prevent abrupt changes in temperature, the place you choose should have constant temperatures.

Keep An Eye On Humidity: Employ a hygrometer to keep an eye on humidity levels, which should be maintained between 5-10%. Silica gel packs are capable of absorbing any excess moisture if the need arises.

Label and Date: Make sure to label your seed containers with the strain name and the date of storage. This will help you in managing your seeds properly and ensure that you will use them within a reasonable time.


Storing Cannabis Seeds

Although seed preservation is crucial for retaining genetics and viability, the storage of harvested cannabis flowers is equally vital. Here are a few suggestions on how to store cannabis flowers:

Use Airtight Containers: Just like seeds of cannabis, harvested flowers are to be stored in airtight containers so that the freshness and potency will be preserved.

Keep it Dark: Put cannabis flowers in a cool, dark place where there is no direct sunlight that can break down the cannabinoids and terpenes.

Control Humidity: Keep the right humidity levels (around 55-62%) to stop mold and mildew growth without the flowers being dried out.

If you follow these rules for the proper storage of cannabis seeds and harvested flowers, you will guarantee the quality and potency of your cannabis products at every stage from seed to shelf. Remember, right storage is an essential factor in keeping the genetics, potency and overall quality for later use.



The transition from seed to shelf is a fundamental part of cannabis growing, and proper seed storage is necessary to keep seeds viable and high-quality. Through understanding the factors that influence seed viability and adhering to best storage practices, you can protect your investment and have bountiful harvests for many years.
