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.Identify best light level of healthy plants Easy to use hand-held design Get precise reading with three scales Includes instructions and "Consumer's Guide to Light Gardening" brochure Lifetime silicon sensor—no batteries required read up to 5000 footcandles of sun, high intensity, or fluorescent light Exclusive "Zero" calibration feature—accurate to 2%.
