About the Strain
PES Hawaiian, also known as PES Hawaii or PESH, is a long-established cultivated variety of Psilocybe cubensis. Its golden-to-caramel caps broaden as they mature, while the pale stems range from slender to moderately thick. The mushrooms generally retain the familiar cubensis form and may develop blue discolouration when bruised.
The name is linked to Pacifica Exotica Spora (PES), a former spore company based in Honolulu, Hawaii. Rather than identifying a confirmed wild collection from the Hawaiian Islands, the geographical name reflects the company's location. PES also distributed the separately named Amazonian variety, making both selections part of the history of the early commercial mushroom-spore market.

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.
