Yes, you can!
How long does it take to add moisture to soybeans?
Varies by airflow rate, 1 cfm per bushel takes several weeks of continuous fan operation with 70% humidity air to bring the moisture to 13%. At ½ cfm it takes twice as long.

Not with the Steps S2 System. The Steps S2 Headspace Sensor monitors the air temperature and humidity above the grain in the bin. When the fan is running it reads the temperature and humidity of the air coming through the grain.

The Steps S2 Control Box is connected to the OSPL Sensor and the Headspace Sensors through the wifi network. The app on your smartphone is connected through the wifi.

Up to a year when the sensors are indoors. Outside with the temperature and humidity changing, up to a couple of months.

It controls the fan (S2 Control Box) based on (OSPL Sensor) air temperature and humidity. Humidity is grain moisture. When you control the fan you control the moisture of the grain in the bin and less grain monitoring is required. The S2 Headspace Sensor tells you the temperature and (humidity) moisture of the grain in the bin while the fan is running. When the fan is off and the sun shines on the roof, the heat builds up under the top of the roof. When you trap warm air in the peak of the roof you create condensation.

Why does that matter?
When the warm air meets cool grain, condensation occurs on the grain, and the grain crusts over. Most of the problems in the bin start on the top surface of the grain with condensation. When the fans operate with the correct air temperature and humidity until the Headspace Sensor verifies the exhaust air temperature and humidity the grain is ready for storage. The Headspace Sensor can be set to control the fans when the grain is being stored.
