  "description": "As many of you will know by now, we at Mephisto love a passion project, and Old School Blues is the ultimate mesh of passion projects. Old School Haze is a strain we’ve worked with before, helping us create our Old School Mango Haze, and it is a strain like few others.\r\n\r\nFor our Old School Blues, we decided to get the insights of Karel’s son and our friend Kees, now the custodian of the Old School Haze cut and one of the brains behind the reinvention of Super Sativa Seed Club, and primary hash maker for the first legal project in the Netherlands.\r\n\r\nLivers is a strain we at Mephisto are still in love with, now going on 25 years since we first sampled it in our hometown of Sheffield. Also known as Blues, Pukkas, UK Blues, Sheffield Blues or Sheffield Livers, she started life, as far as we know, as a Skunk #1 cross, the same as Old School Haze. We say ‘as far as we know’ because Livers has long been a bit of a mysterious strain, with the story and history behind it being mostly anecdotal. We were lucky enough to get our hands on a cutting of ‘The Blues’, a sister cutting of ‘The Livers’, way back before the farm was even a distant dream. Our first autoflower cross of this cutting, some 4 generations later, became Auto Blues.\r\n\r\nWhen we finally acquired a cutting of ‘The Livers’, we outcrossed it to our Auto Blues to create Auto Livers, which was a big improvement of the Auto Blues, but we wanted to refine it and improve upon it even further, crossing it again to the Auto Livers, and working it back to auto in the subsequent four generations. Crossing with Auto Livers now at F4 to create our Livers BX1 strain, a strain that encompasses over 10 years of work and is what got us started with Mephisto Genetics in the first place.\r\n\r\nSo with you all caught up with the lore of a combined 50+ years of work from Super Sativa Seed Club and Mephisto Genetics, let’s get on to why we love Old School Blues. Put simply, we wanted to create a homozygous variety of an autoflowering haze. We knew as soon as we were allowed to sample Old School Haze at a BBQ at Karel’s house that we wanted to work the strain into autoflowering format. The shared heritage of the Old School Haze and our Livers BX1 kindled the shared nostalgia trip we absolutely love when hunting for new strains.",
