When constructing a mushroom substrate sterilizer from a 55 gallon barrel a cavity needs to be created in the lower portion of the barrel to allow room for the heater element and float valve. Our false bottom is plasma cut from 12 gauge steel and includes a spacer "grid" that elevated it 6" from the bottom of the barrel.
- 12 gauge steel perforated false bottom
