Measures the four most important aspects of plant health: light, soil moisture, soil pH and soil fertility. It determines the light level where the plant is located, and the moisture level where it counts - at the roots. Soil pH is measured on a scale of 0 to 9, and a combined nitrogen- phosphorus-potash reading is determined using USDA standards.
