Frequently Asked Questions

How do I store cannabis seeds properly?

Cannabis seeds should be stored in a cool, dark, and dry environment. Use airtight containers and consider refrigeration to extend their viability and protect them from humidity and light.

Can I legally buy cannabis seeds online?

The legality of buying cannabis seeds online varies by country and region. In many places, it’s legal to purchase seeds for souvenir or novelty purposes, but cultivation may require special permits. Always check your local laws before ordering.

What is the difference between autoflower and feminized seeds?

Autoflower seeds begin flowering based on age, not light cycles, making them ideal for quick and easy grows. Feminized seeds, on the other hand, are bred to produce only female plants, which yield consumable cannabis.

How long do cannabis seeds stay viable?

When stored properly, cannabis seeds can remain viable for 3–5 years or more. However, older seeds may have lower germination rates, so fresher seeds are generally more reliable.

Do seed banks ship discreetly?

Yes, most reputable seed banks offer discreet or stealth shipping. This includes unmarked packaging and secure wrapping to ensure privacy and minimize customs issues.

Is it better to buy seeds in bulk?

Buying in bulk can reduce the cost per seed and is ideal for experienced growers or commercial cultivators. However, ensure the seed bank offers germination guarantees and proper storage advice for larger orders.

Can I grow cannabis seeds indoors and outdoors?

Yes, many cannabis seeds are suitable for both indoor and outdoor cultivation. Check the strain’s growing preferences and choose based on your environment, space, and experience level.
