For those with high tolerance levels for pleasing or punishing. Don't laugh too much at those who will lose their minds after hitting this.

Serious Seeds: Best Strains That Can Be Grown By Anyone

This Dutch seed bank is among the oldest in the world, and their goal has always been to give the best possible experience to growers and smokers alike. Serious Seeds’ plants are notoriously potent: independent lab tests have confirmed that their varieties have the highest THC levels on the market, and these from samples that were grown by ordinary gardeners from seeds bought online. From a grower’s perspective, Serious’ plants are especially hardy, vigorous, uniform, and consistently produce massive yields of awesome-looking and smelling buds.

The secret of this company is that they deliberately keep their business small and focus on the quality of their product, never on the quantity of seeds sold or the number of strains on offer. Serious Seeds rejects the common practice of marketing at least one new strain per year, and if they do a major overhaul of a particular genetic variety, they continue to sell it under the old name instead of coming up with a new one. The company is a producer of seeds, not of strain names.

The Early Success And The Future Fame

The seed bank’s story starts with Simon, a biology student from the Netherlands. Despite living in the marijuana capital of the world, Simon’s aversion to tobacco also prevented him from ever trying cannabis (Dutch people had a nasty habit of mixing this herb with tobacco). That all changed in 1986 during a trip to Africa, where Simon got a chance to smoke weed in its pure form for the first time. A rare stroke of luck – otherwise we’d have been robbed of a major breeding talent.

Simon got instantly hooked and spent the next several years collecting seeds, making friends with other cannabis enthusiasts and experimenting with crossbreeding. He dropped his high school biology teaching career to work first for Sensi Seeds, then to open his own seed bank, Serious Seeds, in 1995. A year before that, his two creations, AK-47 and Chronic, were awarded Cannabis Cups, and from then on, the wins just kept coming.

A Dazzling Array Of Trophies

At the time, ganja strains were often entered into competitions by Amsterdam’s coffee shops that had these buds on their menus. So, the very first year Serious Seeds company was founded, its Kali Mist (sometimes referred to as the Queen of Sativas) was presented by the Greenhouse coffee shop – and won. The next year, it was White Russian’s turn, presented by De Dampkring. All in all, Serious’ genetics has collected an astonishing number of trophies: no less than 100, including 25 cannabis cups. Often, the winning buds were grown from store-bought seeds bought by ordinary growers.

Serious Seeds For Sale In Numbered Packages

The company is very serious with regard to the consistent quality of their seeds. In addition to the common practice of manually selecting them and running a test grow to check the plants for uniformity, Serious Seeds is the only company that actually puts a serial number on every pack of seeds. This means that each one can be individually traced back to its origin, from the moment of pollination to the day it sprouts in your bag of soil. That’s how confident this team is that you’ll always get first-rate results out of their genetics.
