Delivery Options

  • Standard Mail – no signature required. FREE on orders over £50, otherwise £5. 

If, like some of our customers, you don’t want to sign for your order, then you should select our standard shipping option. Unfortunately we cannot replace unregistered orders as this would leave us open to abuse. It is, however, very rare that an unregistered parcel fails to reach its destination due to the high standard of shipping methods we employ.

  • Registered Mail –  Guaranteed Delivery, signature required. FREE on orders over £50, otherwise £10.

If you select our  registered mail option then I promise to replace any order that does not reach its destination safely and promptly. No quibbles. Of course, ensure the shipping address you give us is full and correct, as we can’t re-send if it isn’t!

As long as you select registered mail (free over £50) then I will guarantee the safe and prompt arrival of your seeds. If for any reason your marijuana seeds fail to reach you within 28 days then we will either refund you in full or replace your seeds free of charge.


All seeds are in stock and ready for immediate shipping from the UK. Parcels coming from the UK attract far less attention than packages sent from the Netherlands. The strength of my guarantee ensures that stealth is as important to us as it is to you. Less than 1% of our orders fail to reach their destination – after all, we have to pay for them if they don’t arrive safely!
