Humidity Control for Mushroom Growing & Production
Mushroom cultivation requires consistently high levels of relative humidity throughout every stage of the growing cycle. From spawn running and inoculation through to pinning, fruiting, and harvesting, maintaining the correct humidity level is critical to achieving healthy yields, good pin set, and high-quality mushrooms.
Traditionally, humidification within mushroom houses has been performed using steam, as most farms already have steam piped to individual growing rooms for both humidity and cook-out purposes. However, the disadvantages of steam become evident when ambient temperatures are high and steam is injected into rooms to raise humidity levels. In turn, room temperatures rise further, creating additional problems that require cooling units to be activated to bring temperatures back down. The result is not only the high cost of producing steam, but further energy costs incurred to reduce temperatures accordingly.
The use of J D UltraSonics ultrasonic nozzles within spawn running rooms, growing rooms, and refrigeration stores delivers significant advantages to the grower, both improving growing conditions and saving up to 90% on steam energy costs. Connection into existing computer control systems is straightforward as only a simple on/off signal is required to activate the system.
We recommend mounting the nozzle within the polythene duct, as the ultra-fine droplets will float along the length of the duct and gradually disperse out into the room. As a general guide, one nozzle per 500 square metres of growing surface is recommended, though this may vary depending on location, climate conditions, and the type of mushroom being grown. Additional nozzles can be added at any time by simply teeing into the existing pipework.
Our non-drip, non-wetting system is particularly important in mushroom growing, where excess surface moisture can encourage contamination and disease. By maintaining precise humidity control without creating wet surfaces or water dropout, our systems help growers achieve cleaner, healthier crops with fewer losses.
