What Is 420 Day?

420 is the most widely recognised celebration in cannabis culture — a day when enthusiasts worldwide come together to appreciate the plant. As one of the original cannabis seed banks serving UK growers, we honour 420 with competitions, flash promotions, giveaways, and special offers throughout April. Because 420 falls right at the start of the UK outdoor growing season, many growers use this sale to stockpile discounted genetics for spring and summer grows. It’s a chance to secure top-quality seeds at the lowest prices of the year.

420 Day In The UK

Across the UK, 420 has become a major cultural and protest event, with Hyde Park in London acting as the central gathering point where thousands meet each year for picnics, music, speeches and the traditional 4:20pm light-up. The Hyde Park event is widely viewed as a peaceful act of civil disobedience, often described as a mix of protest, community gathering, and open discussion. Smaller 420 celebrations have also appeared in other UK cities such as Brighton, Bristol, Durham, and Leeds, though London remains the largest and most iconic location. For many British cannabis supporters, 420 is about more than consumption — it’s a visible statement in favour of reform, unity, and recognition of the UK’s diverse and growing cannabis community.

Why 420 Matters In The UK

420 gives UK cannabis users and advocates a chance to come together — from different cities and backgrounds — to press for reform, visibility, and recognition. In a country where cannabis remains a controlled substance, 420 rallies create a rare space for communal solidarity, activism, and open public conversation. These gatherings highlight not only recreational use, but also the need for improved medicinal cannabis access, social justice for past convictions, and wider discussions around personal freedoms and drug policy reform.

When Is The 420 Sale?

The official 420 celebration lands on April 20th, but at MSNL, our sale starts even earlier. Our 420 Sale officially begins on April 13th, with newsletter subscribers getting exclusive early access from April 9th.

If it’s April and you’re reading this, now’s the time to get ready—our biggest deals of the year are either live or just about to drop.

Where Did 420 Day Get Its Name?

The origins of “420” trace back to California in the early 1970s, when a group of high-school friends arranged to meet at 4:20pm to search for a rumoured abandoned cannabis crop. “420” became their private code for anything cannabis-related. The term spread throughout US counterculture and eventually reached the UK through music, festivals, and publications. In 1991, High Times magazine helped popularise the phrase globally, incorrectly suggesting it was a police code — a myth that still pops up today. By the mid-1990s, 420 had become a universally recognised cannabis celebration, with 20th April (20/4) chosen as the official date. Today, UK enthusiasts join millions around the world in marking the occasion.
