Based on a design by Myers Mushrooms, our substrate steamer is the easiest, most cost-effective solution on the market. Not intended for use with grain spawn.
A typical cycle will take 14-24 hours. Time is dependent on ambient temperature, substrate temperature, and heater wattage. The 150 gallon model will accommodate almost 600 lbs of substrate. The 150 gallon drums is 51" tall. The larger drum increases capacity but it can be more difficult to load and unload.
