how to store marijuana seeds

Cannabis seeds have three main enemies:

Humidity is easily one of the biggest threats to your seeds. Here is how different levels of humidity (% relative humidity) affect your cannabis seeds:

IDEAL CONDITIONS FOR CANNABIS SEEDS

The ridge is the slightly elevated side of your seed. Like other parts of the shell, this ridge can become extra tough over time. Removing it gently with a sharp Stanley blade can help your seed sprout.

Ziplock bags, for example, are great because you can remove all the air from them to create an almost vacuum-sealed container for your seeds. Once vacuum-sealed, put your bag inside a dark plastic bag or dark container to protect your seeds from your fridge light.

If your seeds get exposed to light or rapid changes in temperature, these conditions will trigger them to use up their nutrient stores before they ever see soil, meaning they won’t have the nutrients they need to germinate. High humidity, on the other hand, can trigger fungi to grow on your seeds.

A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.

With the correct method of storage, cannabis seeds could remain viable for 5-10 years! Seed storage is important for many reasons. Someone who just created their own, high-quality genetics, may want to keep the seeds to reproduce the strain.

WHY IS PROPER SEED STORAGE NECESSARY

It’s also important to note that when freezing seeds, every time they are thawed and refrozen, they become less viable. Both freezing and refrigeration can also lead to excess moisture, so that’s something that needs to be monitored closely.

Cannabis seeds should be stored somewhere cold and frigid. Whether you store your seeds in a freezer, refrigerator, or even a cabinet or drawer, it’s important to leave them there until it’s time to germinate. Rapid temperature variations will destroy the genetic integrity of your seeds.

When cannabis seeds are properly stored, most growers find the majority are still full of life after five years. Many growers have even grown high-grade cannabis with seeds up to 10 years old.
