The SA2500 Sun Analyzer is a 'Solar Energy' responsive instrument specifically designed for measuring the radiant energy of sunlight, which affects plant growth. The instrument is calibrated in foot-candles to accurately display the 'mean solar radiation' available in any location.
Each plant species requires a known minimum amount of sunlight accumulation during an entire day of sunlight exposure. Each plant’s specific light requirement is a result of years of trial and error research. Leading research centers and nurseries have standardized these requirements.
It is vital for optimum growth that a plant be positioned so that it is exposed to its light intensity needs. The basic design concept of the Sun Analyzer is to optimize the positioning of plants, eliminating the associated guesswork implied by terms such as full sun, partial shade and shade. Our extensive research has uncovered a definitive foot-candle hour factor for each of these widely used terms.
Comes with complete manual and plant cross reference list.
