McKennaii — Spore Swab Cloud920®

McKennaii — a Dutch homage to Terence McKenna

You look for a cubensis with real character on the microscope slide, and you want its story straight. McKennaii comes out of a Dutch commercial grow lab — released as a tribute to Terence McKenna, not discovered by him. Under the lens you get dark purple-brown spores, high contrast, and clean spore walls. Your McKennaii Spore Swab Cloud920® delivers that reference material in a sealed, sterile vessel.

Origin & Genetics of McKennaii

McKennaii was developed in the Netherlands by commercial growers for the Dutch smart-shop market, and named as an homage to psychonaut and ethnobotanist Terence McKenna. This is important for your catalog: McKennaii is a cultivated isolate of Psilocybe cubensis, not a wild variety and not a hybrid. Terence McKenna did not collect or discover this strain himself — the name is a tribute. That distinction keeps your reference labelling accurate.
