Its not a breeder or seedbank, clone only strains are only available as clones. Mostly they are special selected phenotypes of a commercial strain, or old classics who was keeped by someone somewhere...

The Psychosis is a legendary UK clone-only strain (1990s sensi NL X 5 haze) that came from the founders of UK Exodus Cheese. It grows with a sativa architecture and classic Cheese vine-like structure, with excellent resin production as early as 3 weeks after 12/12. It coats itself through the 9 weeks it takes to finish. Calyxes should start to tower at 6 weeks of 12/12 lighting. The buds will finish rock hard, glistening with THC.
