Why Humidity Matters
Mushrooms are 90% water, and they absorb moisture directly from the air. During fruiting, maintaining 80-95% humidity is critical. A fine, even mist — not large droplets — is the best way to keep humidity high without waterlogging your substrate or damaging delicate pins.
How to Use
Fill with clean, filtered water. Adjust the nozzle to the finest mist setting. Mist 2-3 times daily around (not directly on) your grow kit or fruiting chamber. The goal is to humidify the air, not soak the substrate.
Tips
- Use filtered or distilled water to prevent mineral buildup
- Mist the walls of your humidity tent, not the substrate directly
- Keep the nozzle clean — flush with warm water weekly
- Avoid tap water in areas with high chlorine
