How to store cannabis seeds?

Storing marijuana seeds correctly is incredibly important when it comes to germination; if you don’t store them properly, they end up deteriorating and losing germination power. In order to increase their lifespan, you should keep them in a cold area, with temperatures between 6- 9 °C and a humidity range of 20-30%.
