So while purchasing seeds is legal, cultivation is not permitted without proper licensing.

Why Are Cannabis Seeds Legal But Growing Is Not?

Cannabis becomes a controlled substance under the Misuse of Drugs Act 1971 once it begins to grow and produce THC.

Seeds:

Plants:

Produce THC once cultivated

Are classified as a Class B controlled drug

Require a Home Office licence to grow legally

This distinction is why you may see seeds openly sold online in the UK.
