How to Properly Store Cannabis Seeds
Proper preservation is essential for extending lifespan
Cannabis seeds are dormant organisms that require careful handling and storage to maintain their viability. Proper preservation is essential for extending their lifespan and unlocking the genetic potential they harbour, which is crucial for cultivating a robust and productive crop. Below are some comprehensive guidelines on how to effectively care for your cannabis seeds.
What are the Ideal Storage Conditions for Cannabis Seeds?
While cannabis seeds can appear durable due to their tough outer shell, they are highly sensitive to environmental conditions. To ensure they remain viable for future planting, it is crucial to store them at stable temperatures and moisture levels.
Among these factors, humidity plays a pivotal role in the longevity of cannabis seeds. If the humidity drops below 10%, the seeds' life cycle can be severely interrupted, leading to a significantly shortened lifespan. Therefore, maintaining proper humidity levels is paramount.
What is the Optimal Humidity Range for Cannabis Seeds?
The optimal humidity range for preserving cannabis seeds lies between 12% and 15%. This specific range is ideal for promoting the seeds’ longevity and genetic vitality, allowing for the best possible yield once germination occurs. Reputable seed banks utilise state-of-the-art techniques to maintain this precise level of humidity, ensuring that the seeds remain in peak condition.
When the relative humidity hovers between 16% and 21%, seeds can still survive, but their overall lifespan diminishes. Conversely, levels exceeding 40% lead to gas exchange between the seeds and the surrounding environment, posing risks if you’re not ready for germination. At humidity levels above 80%, the seeds are highly likely to germinate, which may not align with your intended timeline for planting.
How can you extend the Lifespan of your Cannabis Seeds?
To effectively preserve your cannabis seeds and maximise their shelf life, one of the best home methods involves storing them in an airtight glass jar within the confines of a refrigerator. This cool, dry environment is ideal for preserving seed vitality. Additionally, placing small packets of silica gel inside the jar can help absorb any excess moisture, stabilising the internal humidity levels even further.
For those seeking even greater protection, vacuum sealing your cannabis seeds can significantly enhance their longevity. This method effectively removes air from the packaging, minimising the risk of moisture and oxygen exposure, both of which can lead to seed degradation.
How Can You Manage Light Exposure?
Beyond humidity and temperature, stable lighting conditions are essential for seed preservation. Cannabis seeds should be shielded from sunlight and harsh artificial light, as both can trigger premature ageing and reduce viability. Store the seeds in a dark, cool place away from any light sources to ensure they remain in optimal condition for when you are ready to plant.
By adhering to these comprehensive guidelines, you can effectively store your cannabis seeds, allowing them to retain their genetic potential and ensuring a successful cultivation experience.
