This is the first year that we did not have a spoilage issue coming into the spring season due to using the Grain Temp Guards®. We have been able to monitor what was going on in the bins before it actually went bad. By being able to watch the temperature and humidity in the bins, we were able to harvest and put our grain into the bins wetter than what we were doing blindly before…. I felt more comfortable being able to watch what was going on. I know some guys who have other versions but dollar wise Grain Temp Guard® seems to be the more doable for a multi-bin situation.
