Active Eye Analog Light Meter (Footcandles)

Photosynthesis and plant growth depend on the sun or specially-designed lighting systems. But of that light reaching the plant, only specific types of energy (in the lighting spectrum) drive the photosynthesis process. Since light is the most important single factor affecting your plants' life cycles, quality light meters are an essential tool in accurately determining if your crop is receiving the maximum light needed for healthy growth. A light meter allows growers an accurate means of adapting to their plants' needs as the light conditions change during a full growing season.FeaturesIdentify best light level of healthy plantsEasy to use hand-held designGet precise reading with three scalesIncludes instructions and "Consumer's Guide to Light Gardening" brochureLifetime silicon sensor—no batteries requiredRead up to 5000 footcandles of sun, high intensity, or fluorescent lightExclusive "Zero" calibration feature—accurate to 2%Full two year warranty—the longest in the industry
