Why humidity and temperature control matters
Mushrooms need high, even humidity throughout cultivation. Air that is too dry makes them dry out, crack and grow slowly, with uneven yields.
- Dry, cracked mushrooms
- Slow growth and lower yields
- Uneven humidity across the house
Our recommended approach
JB ultrasonic humidifiers produce a very fine mist and are compact, portable and rust-free with a moisture-proof plastic housing.
