About Us

Castle Marijuana Seeds

Our collection of cannabis seeds represents the most complete selection of marijuana strains available from any source. We stock both regular and feminised varieties and we only buy from reputable seed banks.

Our fast turnaround ensures we never hold seeds for more than a few weeks. Our seeds are stored in refrigerators at optimum temperatures and conditions to keep them fresh. We put a lot of thought into the way we package your order. Seeds are expensive and vulnerable – and in our experience many mail order companies do not treat seeds with the respect they deserve.

Please do note that our marijuana seeds are sold as souvenir items. Any information about germinating, growing, smoking or doing anything with seeds other than keeping them as souvenirs is intended only for people who reside in countries where growing cannabis is permitted. In the UK it is illegal to germinate cannabis seeds without a license from the home office, and therefore if we suspect or are made aware that you intend to germinate or have germinated our marijuana seeds, we will be unable to take your custom.

* Like-for-like price matching (breeder and strain must be the same).


PLEASE NOTE: We can only replace or refund orders if you have entered the correct name AND address at the checkout.
