What does 420 mean and why is it a symbol?

The number 420 has gone from being a student code in California to becoming an international symbol of cannabis culture. Today it appears at festivals, on t-shirts, and in the media.

It is also associated with growing cannabis from marijuana seeds, an increasingly common practice among enthusiasts and patients seeking independence and safety in their consumption.

What does 420 cannabis mean?

The term originated in the early 1970s. A group of young people from San Rafael, known as “The Waldos,” used the expression 420 to meet at 4:20 p.m. and smoke marijuana discreetly. Over time, the number spread to concerts and university communities, eventually becoming a shared symbol worldwide.

420 cannabis is now synonymous with identity and belonging within cannabis culture, with a value that goes far beyond an hour on the clock.

The Role of Home Growing

For many enthusiasts, 420 is also an invitation to grow the plant at home.

The first step is choosing reliable marijuana seeds, as much of the final result depends on them.

Taking care of the plant yourself is a practical way to connect with the 420 philosophy: respect for nature, personal responsibility, and freedom of choice.
