ABSTRACT:
Method and apparatus for encouraging maximal plant growth which method and apparatus comprise a light filter which prevents the natural decay of plant growth stimulating materials by absorption of UV radiation while permitting photosynthesis to occur with blue light in the absence of attendant heat generating and dehydrating radiations caused by green, yellow and infra-red light. The objective is made possible according to the preferred embodiment of the invention by interposing separately, continuously, or discontinuously, a combination of filters made of solid material between the sun and the growing plants which block out radiation in those wave lengths which are either physiologically harmful or which retard growth, but do not inhibit those wavelengths which are necessary for photosynthesis, metabolism, differentiation and development.
