Temperature: Reishi mushrooms thrive in temperatures around 22-28°C (72-82°F).

Humidity: Maintain humidity levels around 80-90%.

Tips: Mix coffee grounds with wood chips or straw to create a substrate that mimics their natural habitat. Reishi mushrooms require a longer incubation period, so be patient during the colonization phase.
