    Grain storage moisture-control field test results from a shipping container near Dallas, Texas

    Storing Grain & Keeping it Dry

    John, a customer near Dallas, Texas, stores one-ton sacks of grain inside ground-level shipping containers. The grain is elevated on pallets so it does not touch the floor. Despite this, the sealed containers would regularly trap heat and humidity, creating moisture conditions that damaged the grain and produced toxic, overwhelming fumes—especially during periods of high heat.

    Moisture Control Field Test Results

    Early Spring 2019

    The field test began with temperature and humidity readings inside and outside the shipping container.

    2 YEAR UPDATE

    John reported that grain loss had been cut from 20–30% to 0%, with moisture at approximately 14%.

    2023 Update – 4th Year

    Moisture remained between 13.5% and 14.5%, with 0% loss over four years.

    January 2026 – Final Update

    The seven-year study concluded with 0% grain loss.
