Serious 6 was created by mixing genetics from Canada with Sativa-landraces from Africa through a long process of selection and cross-breeding. Serious Seeds wanted to create a strain, which is very mold-resistant and will finish EARLY outdoors in a humid and cold climate at the end of September. Outdoors she grows tall and slender with full buds with very few small leaves and a particularly thick layer of cristals. Half of the plants will show beautiful pink pistils. At the end of flowering these pink colors are substituted by purple colors of the calyxes and leaves. The Serious 6 is an almost pure Sativa with a very short flowering time, which also gives amazing results indoors. She will fill up and produce dense long buds glistening with trichomes. The aroma of Serious 6 cannot be compared to other cannabis varieties, it is built up in layers; citric, anise, spicy are only a few of the recognizable aromas. Her effect is a cristal clear head-high, which will get you active and creative. At the Spannabis 2013 an indoor bud was tested at the CANNA-lab with 17% THC, that was the highest measured THC-content of ALL strains tested that day!

Like many seed banks across the world, Serious Seeds began with one man’s journey and for Serious Seeds, that man is Simon.

The founder of Serious Seeds, Simon started life as a non-smoker. However, in 1986 during a trip to Africa, he discovered his love for marijuana. For nearly a decade, Simon was cultivating genetics for personal use, experimenting with his favourite strains in order to satisfy his own tastes.

However, as more people began trying his product, he found himself changing professions from High School teacher to full time breeder with Sensi Seeds. After a year of working in a popular seed bank with Sensi, Simon decided to start his own company and in 1995, Serious Seeds was born.

Immediate success ensued, with a Cannabis Cup win in Serious Seeds’ first year as an active seed bank. That was followed up a year later with another Cannabis Cup win for his White Russian strain. An amazing start for such a new breeder.

Simon has always been keen to keep Serious Seeds a relatively small seed bank. However, their size has never diminished the quality of their seeds or their reputation as one of the most coveted seed banks in the world. You can enjoy Simon’s legendary strains for yourself; buy Serious Seeds from Seedsman now.
