Customer Reviews
Easy to find what I needed
I was just browsing for some high THC seeds and stumbled onto this site. It was super easy to navigate and find exactly what I wanted. Placed an order for some Gorilla Glue seeds. Shipping was discreet too, which was cool. Everything went smoothly, no complaints.
Good range, slight delay
I bought some White Widow feminized seeds from here. They have a really good selection of different strains, which I appreciated. The ordering process was easy enough. Delivery took a little longer than I expected, around 8 days, but it did arrive eventually and was very discreetly packaged. The seeds themselves looked healthy. I wish delivery was a touch faster, but everything else was fine.
Consistent service as always
I've used Cannabis Seeds UK a few times now, mainly for their auto-flowering seeds. This order for Northern Lights seeds was just as reliable as the others. The stealth shipping is always on point, and they usually get here within a week. That consistency is why I keep coming back.
Good value, free seeds
I was looking for some indoor seeds and found Cannabis Seeds UK. The prices seemed fair, especially with the 10% off for first-time buyers. I also got some free seeds with my order which was a nice bonus. Felt like a good deal overall and saved some money.
Decent experience, useful site
My recent order for some Amnesia Haze feminized seeds was a generally positive one. The website was straightforward to use; I found the search filters for indica/sativa and high THC quite helpful. Delivery took about 6 days to reach me, which was anticipated. The packaging was very discreet, no branding on the outside. I paid with a card, and the process was smooth. The free seeds included were a nice touch, though I haven't tried them yet. Overall, a solid service and the product quality seemed good upon arrival.

Share tips, ask questions & help fellow shoppers save more
Anyone know if they actually send free seeds with every order? Or is that just for specific deals? Trying to figure out if I should save up for a bigger order.
Hey guys, thinking of ordering some seeds from here. What's shipping like to London? Does it take ages or is it pretty quick?
