5 O'z 5

MephistO’z has cemented itself amongst the Pantheon of Mephisto strains, a first round draft pick to the Hall of Fame and is well on its way to getting a coveted place up on Mount Mephmore. In the two years since we first released MephistO’z (under a different name, for legal reasons) our social media has been bombarded with requests for practically every strain in the catalogue to be given the O’z treatment. Finally, we relented, and the only real solution to picking which strains got the second round of O’z was to put it out to a community vote. Meph Heads do community involvement like few others; the voting for the O’z crosses was a full on World Cup of Meph; we had group stages, groundroots campaigns, gangs forming, arguments, love-ins and a knockout round that got feistier than a lock-in in a Pitsmoor alehouse. Eventually the community managed to select their 8 champion strains to be crossed with O’z, and the Mephisto staff also selected their 4 worthy runners up to join the lineup. As true F1 Limited Editions, these strains haven’t had the extensive mass-testing that a main catalogue strain goes through. Available exclusively in packs of 6 seeds.

This is a bit like strapping a rocket to MephistO’z and sending her into orbit. You’ll probably end up feeling like you’ve been launched into space too. 505 Headbanger won the Highest THC award at the 2026 edition of the American Autoflower Cup, and she has consistently been talked of as one of the strongest strains in the lineup since her release in March of 2025. If Sour O’z hadn’t already been selected as a name, that would be an incredibly apt name for this one instead. Sour Diesel and Oooze as grandparents? Count me in. There might be some packs left for sale once the staff have got their hands full.
