Enviro Controller High Humidity Replacement Probe (Mushroom Probe)

A humidity probe built to survive genuinely wet grow rooms

The Enviro Controller High Humidity Replacement Probe, widely known as the Mushroom Probe, is made for the extreme conditions where standard sensors drift or fail. Its specialised lacquered coating resists moisture and condensation, so it keeps reading accurately above 80% RH, exactly where mushroom cultivation and high-humidity propagation live. It plugs straight into compatible Enviro Controllers and IHC controllers via the external plug-and-play probe port, and even after heavy misting or a splash it dries out and carries on working, which is what makes standard probes unreliable in these rooms.

Key Benefits

• Built for 80%+ RH environments where standard probes lose accuracy
• Lacquered coating resists condensation, humidifier mist and water droplets
• 5m cable for flexible probe placement inside a grow tent or grow room
• Plug-and-play compatibility with Enviro Controllers and IHC controllers
• Fast recovery after heavy moisture exposure so readings stay accurate
• Durable build tested in demanding commercial environments

How to Use

• Locate the external probe port on your compatible Enviro Controller or IHC controller.
• Plug the replacement probe into the controller's plug-and-play sensor port.
• Position the probe at canopy height for accurate readings.
• Keep it away from direct fan or ventilation outlets for the most stable measurements.
• The controller automatically begins using the new probe to monitor humidity.
