Measure your plants' most important inputs: light exposure and temperature. Also tracks degree days and chill hour data. The WeatherTracker 305 includes a quantum light to measure your plants' light exposure over time (in moles/day). The 305 is a comprehensive tool to assess physiological maturity of your plants.

Greenhouse Light WeatherTracker calculates Growing Degree Days

The internal electronics calculate Growing Degree Days (GDD) for up to three degree day counters. For example, one counter can be activated at planting while another can track the development of insects.

The station also calculates Chill Hours, which is the total amount of hours during which temperatures have been below a specified low temperature. The arrow keys allow you to scroll through the sensor readings, Degree Day/Chill Hour calculations, as well as set your temperature ranges.

WeatherTracker monitors the PAR light available and records it as moles/day.
