Not happy with your new cannabis seeds? Receive the wrong item? Simply change your mind?

Returns are never a problem when The Rhino's large & in charge. Follow these instructions and we'll set everything right:

  • Do not open the sealed breeder pack. Rhino Seeds only accepts unopened returns.
  • Contact our customer service department for an RA number.
  • Pack your unwanted items in a padded mailer with the RA number & your contact info.
  • Ship your package postage paid using trackable Royal Post to Rhino Seeds at the address shown below.

Send all returns to:
Rhino Returns
PO Box 456
Weston Super Mare
BS29 6HE

Once your items reach the Rhino Seeds' warehouse, we'll process your return as fast as possible. In most cases, the entire process only takes 3 to 4 business days, but it can take a little longer during peak seasons.

Rhino Seeds will issue your refund in the same format you used to make your payment. Note that each financial institution has their own policies and procedures that can affect how long it takes for your funds to reach your account. Unfortunately, not even The Rhino has control over that little fact of life.

If you have any questions about this process, the status of your return or the next scheduled alien invasion, don't hesitate to contact us by phone, email or snail mail. The Rhino Team is always here to help!

The Rhino Always Delivers!

Whether you choose an old-school cannabis seed, a brilliant new feminized strain or an ultra-fast autoflowering hybrid, Rhino Seeds backs every order with a 100% delivery guarantee, and we protect your privacy with absolutely discreet packaging. You always get exactly what you expect when you deal with The Rhino!

  • 99% of Orders Delivered within 48 Business Hours
  • Plain Mailers with No Identifying Information

  • Fast Communication if any Issues Arise

Purchasing cannabis seeds in the UK for collection, preservation or souvenir purposes is perfectly legal, but that doesn't mean you want everyone to know about your little hobby. Discretion, privacy and personal security should be The Rhino's middle names, but that would never fit on his driving license.

Instead, we conceal the contents of your order from prying eyes with 100% discreet packaging in the form of a plain padded mailer with absolutely nothing on the outside except your delivery address. We'd skip that too, but we haven't found a single postman who can read invisible ink - yet!

The Cheapest Prices in the UK - Guaranteed!

The Rhino doesn't just match prices, he beats them to a pulp! To make sure you always get the absolute best deal in the UK on the finest cannabis seeds in the known (& unknown) universe, Rhino Seeds backs every purchase with his unbeatable Best Price Promise.

Here's how it works:

  • Buy your choice of 5-star cannabis seeds from Rhino Seeds.
  • Find them for less at another VAT-registered seed bank - we dare you!
  • Let the friendly rhinos who man our customer service department know.
  • If everything checks out, you'll get a refund for the difference plus a fiver.

No one can beat The Rhino's Best Price Promise! In fact, other seedbanks don't even try - they just ignore us & hope we'll go away.
