Garden HighPro Thermo-Hygrometer with 1.5m Probe | Digital Indoor Grow Tent Humidity & Temperature Monitor | Dual Zone Min/Max Memory

The Garden HighPro Thermo/Hygro with 1.5m Lead is a professional-grade environmental monitor designed for indoor horticulture. Its standout feature is the dual-sensor system: a built-in internal sensor for ambient readings and a secondary external probe on a 1.5-metre cable. This allows growers to keep the digital display outside a grow tent or at eye level while precisely monitoring the climate at the plant canopy or within the root zone.

The unit features a large, high-contrast LCD screen that provides immediate visual data on humidity and temperature trends, helping to prevent issues like heat stress or mould by ensuring the environment stays within the "sweet spot."

The 1.5-metre lead allows you to place the sensor probe directly under your grow lights or tucked into the foliage. This ensures you are measuring the temperature your plants actually "feel," rather than just the general air temperature near the walls.

A critical tool for growers; this function tracks the highest and lowest points reached during the day and night. This is essential for identifying if your fans are failing to keep up during peak light hours or if humidity is spiking during the dark cycle.

Designed for high-humidity environments, the casing is made from impact-resistant ABS plastic. It includes a fold-out stand for flat surfaces and a recessed mounting hole for secure wall or tent-pole attachment.

By providing both "Indoor" (unit location) and "Outdoor" (probe location) readings, you can monitor the differential between your intake air and the heat generated by your lighting system simultaneously.
