Penis Envy mushrooms grow slower due to their dense structure and higher psilocybin production, which requires more time to develop.

Key reasons Penis Envy takes longer:

• Selective breeding for specific traits results in slower mycelium growth and longer colonization times.
• They require precise temperature, humidity, and air exchange—fluctuations can slow growth.
• Their thick, dense stems and smaller caps take longer to mature than other Psilocybe cubensis strains.

Penis Envy mushrooms produce fewer spores, making the initial colonization phase slower and more challenging.
