Bean sprouts growing conditions
1. Ground requirement
Under normal circumstances, the production site can choose idle buildings, open space and so on. Requiring a certain degree of temperature control, ventilation facilities, having a better water supply and drainage functions.
Intelligent control of the temperature of the water tank, the temperature inside the box, the time of pouring water, and the automatic alarm protection function of water shortage. It’s safe and reliable, easy to operate.
3. Disinfection of the site:disinfection once a month.

The minimum can not be less than 75% (if less than 75%, spraying water to ground and air, increase humidity). If the humidity is not enough, bean sprouts grow slowly and irregular, it is easy to fibrosis, bad taste, and low yield.
The minimum can not be less than 15 degrees, the maximum can not exceed 35 degrees. If less than 15 degrees, these figures can be directly selected from the sprouting machine, it can be taken to increase the temperature of the artificial heating method. If more than 35 degrees, ventilating and watering sprouts to reduce temperature.
