RuntO'z

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.

A multi-award winning strain, Mango Runtz was the standout release from 2025. Sweeping the Best New Strain category at both the Autoflower World Cup & American Autoflower Cup; Mango Runtz has sat at the tippy top of the Meph Mountain consistently in the two years since her release. Runtz lives up to her name, with her squat and stocky stature, so expect any O’z leaning phenos to gain some solid height but still retain that almost offensive candied fruit aroma and flavour of the Runtz.
