Cultivation Profile

Growth Characteristics:
Fast colonizer; thrives in cooler fruiting conditions. Produces large, overlapping clusters with rich blue coloration.

Colonization: 60–70°F (15–21°C)

Substrates: Straw, hardwood sawdust, coffee grounds, or supplemented blocks

Fruiting: 50–65°F with 85–95% humidity
