About the Strain
Yeti is a pale variety of Psilocybe cubensis, recognised for its ivory-white to cream-coloured caps and thick, substantial stems. The caps are initially rounded but may remain partly closed or develop irregular shapes as they mature. Some specimens show faint beige or blue-grey tones, while the stems can become uneven or slightly twisted. Blue discolouration may appear where the tissue is bruised. Despite the pale appearance, mature spores are generally dark purple to almost black.
The variety belongs to the True Albino Teacher (TAT) family and is historically associated with breeder Jik Fibs, who also developed the original TAT selection. Ghost emerged as a separate branch of the same family, while later developments include Yeti 2.0 and Nutcracker. These selections reflect the continuing development of distinct forms within the wider TAT lineage.
The variety has also entered modern genetic research. On 3 December 2025, a whole-genome sequencing record was registered in the Psilocydia database under the identifier PSP10160, adding molecular documentation to its established cultivation history.

Is a Heat Mat Really Necessary?
In most homes, it's possible to find a suitable spot with enough light and a reasonably stable temperature, so a heat mat is usually not necessary. If the surroundings are too cool, additional warmth may be helpful. A heat mat can be used on its own, while an optional thermostat offers more precise temperature control when needed.
