85 Gallon Mushroom Substrate Steamer

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 85 gallon model will accommodate 300 lbs of substrate.

• New 16 gauge 85 gallon all welded stainless drum.
• Temperature & run time controller with heating element
• Insulated with Armaflex and jacketed with neoprene
• Vented lid with thermometer
• False bottom
• 2” ferrule with clamp for heating element
• ½” drain with stainless ball valve.
• Stainless float/fill valve.
• Pressure regulator
• Braided fill hose

The included controller allows you to set the target temp and run time. It features a stainless steel enclosure, indicator lights, safety lockout, and temperature probe. The controller ensures accurate and repeatable results while minimizing electrical consumption and saving time. The controller requires 3 wire plus a ground wire; single phase 240v power. 240 volt single-phase service must include a ground and a neutral..

A 30 amp rated extension or power lead with a L14-30 connector is required to run the unit at 240 volts. They are readily available from Amazon or your local home improvement store. ** Orders shipped after 1/1/24 will no longer utilize the L14-30 plug. The controller will contain a cord grip and will need to be hard-wired. If you are not confident in your ability to wire the controller, please seek out an electrician.

Watch the Myers Mushrooms video on putting your substrate steamer together. Note that the false bottom design has changed since this video was made. The new system is simpler and self-explanatory.
