Why Steam Sterilization for Mushroom Grow Rooms?

Steam sterilization is an effective method for sterilizing a mushroom grow room, as it eliminates pathogens, mold, and pests without leaving chemical residues that could harm sensitive fungi. Room temperatures of (160-212°F / 71-100°C) kill bacteria, mold spores, mites or flies, which are common threats to mushroom crops. Chemical Free: Ideal for mushroom cultivation, where chemical residues can inhibit mycelium growth or contaminate edible mushrooms. Steam effectively sterilizes porous surfaces, substrates, and hard-to-reach areas like corners and ventilation systems.

Pasteurization of Growing media

• Steam Injection: Involves using steam to heat the straw to the desired temperature. This can be done in a specialized chamber or using a simple setup with a barrel and a steam source.

• Hot Water Bath: Steam is used to heat a tank / cistern of water and then straw is submerged into the hot water @ 65-82°C (149-180°F) for 1-2 hours then placed on a concrete pad surface to cool down.

  Post-Crop Pasteurization

• Steaming off a room with substrate to 150 - 185°F (66 - 85°C) for at least 12 hours.
