The month of April has arrived, which signals a time of significance for stoners all around the world, because it means 4/20 is closing in! As many will know, 4:20 on April 20th is cannabis o’clock, and time to light up. But 4/20 is also a highly regarded date that marks the annual celebration of all things cannabis. Every year, cannabis lovers from many nations join together in large cities such as London, Vancouver, Denver, and Amsterdam to smoke cannabis (legally or illegally, depending on location) as an act of mass appreciation for the herb. To mark the celebration, Royal Queen Seeds is offering a massive 20% discount over a 4 day period, to celebrate these special numbers. Take advantage of this promotion and procure yourself some high quality cannabis seeds, paraphernalia, and merchandise.



4/20 is a combination of numbers that is shrouded in mystery. There are many different claims that have evolved over time attempting to explain what exactly these numbers mean. Some state it’s a covert police dispatch code that signifies people breaking the law by consuming cannabis. Others stake a more scientific claim, explaining that it’s the number of chemicals within the plant.

The truth is, the origins are a lot more simple and humble than this. It turns out this worldwide phenomena comes from a select group of high school students from San Rafael High School, California, who decided that 4:20pm would be the time they would meet up after class and attempt to locate a rumoured cannabis plantation around the area of Point Reyes Peninsula. Although their efforts did not succeed, the group of young men decided to keep these numbers and use them as a group code word when referring to all things weed.

But how did this random group of guys manage to catapult these numbers onto the world cannabis stage? Well, they stumbled upon a rather large platform. The group, who labelled themselves “The Waldos”, ended up forming a friendship with the legendary American rock band Grateful Dead. The band eventually adopted the numbers, even using them in promotional flyers as concert times and dates. This led a small group phrase to evolve into one recognized by practically every cannabis user on Earth.

Knowing the correct history of 4/20 adds even more meaning to an already unique day. Now it’s time to review some of the best cannabis strains available to enjoy on the day.



4/20 isn’t just another day of smoking. It’s basically an annual vacation dedicated to weed, therefore it only makes sense to smoke the best you can find, and to smoke with a purpose. All of these strains will get you baked, but each of them have their own unique qualities that will allow you to enjoy the day’s activities.


Sour Diesel is famous for igniting cases of the giggles, which is ideal for such a large celebration. Sparking up this sativa-dominant strain at the biggest 4/20 event you can access will instantly land you in a great mood. It will make you extra sociable, chatty, willing to meet new people, and most of all, it will make you laugh. It’s as though Sour Diesel places a new lens over your eyes that makes almost everything appear bright, fun, and more humorous. The 30% indica genetics eventually allow this long-lasting high to taper off into a chilled body stone. This means it’s either time to go home or smoke more! THC levels of 19% make for instant highs, be sure to share this one around the event to initiate as many good moods as possible. A strain with vibes this good was only made possible by crossbreeding parent strains Original Diesel, Northern Lights, Shiva, and Hawaiian. Along with this giggly high come nice flavors of herbs and sourness.

If you enjoy this strain on 4/20, then consider growing your own stash at home. You won’t be disappointed in the yields. When grown indoors, Sour Diesel puts out great yields of 16.8 – 18.5 oz/m², grows to heights of up to 62.4 inches, and has a flowering time of 10–11 weeks. Outdoor plants provide large yields maxing out at 21.2 oz per plant, grow to soaring heights of 78 inches, and will be ready to smoke up in late October.

Royal Bluematic is the ideal strain to experience the extremes of what cannabis can really taste like.

Every toke of this strain ignites the taste buds with hits of sweetness, berries, fruit, and sugar. She’s extremely moreish, but THC levels of 14% mean you can get away with tasting her for quite a bit. Be sure to share some around the event you attend to show people another taste of cannabis!
