Enviro Controller High Humidity Replacement Probe (Mushroom Probe)

The Enviro Controller High Humidity Replacement Probe, often referred to as the Mushroom Probe, is designed for extreme humidity environments where standard probes can fail. Built with a specialised lacquered coating, this probe is highly resistant to moisture and condensation, making it ideal for grow rooms operating above 80% humidity. It connects directly to compatible Enviro Controllers and IHC controllers via the external plug-and-play port, providing reliable environmental monitoring in demanding indoor growing conditions.

In hydroponics and indoor growing setups, accurate humidity monitoring is essential for maintaining plant health, stable vegetative growth, and proper flowering conditions. This heavy-duty probe ensures humidity readings remain consistent even when exposed to mist from humidifiers, foliar sprays, or very damp grow environments.

Key Benefits

• Designed for extremely high humidity environments (80%+ RH)
• Special lacquered coating improves water resistance
• 5 m cable allows flexible probe placement within grow tents and grow rooms
• Compatible with Enviro Controllers and IHC controllers with external probe ports
• Durable design tested in demanding commercial environments
• Recovers quickly even after heavy moisture exposure

How It Solves Grow Problems

Humidity sensors can easily fail in indoor growing spaces where moisture levels are high. Standard probes may become inaccurate or stop working when exposed to constant humidity, humidifier mist, or accidental water exposure during foliar feeding.

The Mushroom Probe is built to handle these conditions. Its protective coating allows it to withstand condensation, water droplets, and extremely damp environments without losing accuracy. Even if the probe becomes wet, it can dry out and continue working correctly. This reliability makes it ideal for high-humidity grow rooms, propagation areas, and environments where precise humidity control is needed to support healthy plant growth, stable vegetative development, and strong flowering results.

How to Use

1. Locate the external probe port on your compatible Enviro Controller or IHC controller.

2. Plug the replacement probe into the controller’s plug-and-play sensor port.

3. Position the probe inside your grow tent or grow room at canopy height for accurate readings.

4. Avoid placing the probe directly in front of fans or ventilation outlets for the most stable measurements.

5. The controller will automatically begin using the new probe to monitor humidity levels.
