Unfortunately, we can't guarantee germination.
In the UK, it is only legal to sell cannabis seeds for souvenir and collection purposes. Because germination is illegal in the UK and most other countries, it would also be illegal for us to replace seeds that fail. Until the laws in the UK change, our hands are tied. This is a standard business practice for virtually all seed banks and most breeders.
We will replace any seeds that were damaged in the post. Simply return them to us in the same condition they arrived to receive like replacements.
