how long can you store cannabis seeds

  • Light
  • Humidity
  • Temperature changes

Cannabis seeds, with their tough outer shell, seem pretty hardy. And while nature has definitely designed them to hold up to a wide variety of conditions, cannabis seeds aren’t invincible. Rapid changes in temperature and high humidity, for example, can quickly ruin a batch of seeds. Luckily, caring for your seeds is simple. Keep reading to learn how.
At Royal Queen Seeds, we take pride in our work and want to ensure every grower only has the best genetics in their garden. That means we inspect all of our seeds before packaging. If you notice any damage to your RQS seeds, get in touch with our customer service team immediately.

Ideally, you want to store your seeds in a cool, dark, and dry place. Whenever possible, keep your seeds in their original packaging. At Royal Queen Seeds, we’ve specially designed our packaging to protect our seeds until you’re ready to plant them.

  • Slice open your seed

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.
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.

  • Scar your seeds

If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.

When stored properly, your cannabis seeds can easily hold up for numerous years. Click here to learn how best to preserve your weed seeds.
