Light Spectrum and Absorption<br />
<br />
200-280nm UVC ultraviolet range, which is highly toxic and extremely harmful to plants.<br />
280-315nm Includes harmful UVB ultraviolet light, which causes plant colors to fade.<br />
315-380nm Range of UVA ultraviolet light that is neither harmful nor beneficial to plant growth.<br />
380-400nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.<br />
400-520nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis (promotes vegetative growth.)<br />
520-610nm This range includes the green, yellow, and orange bands and has less absorption by pigments.<br />
610-720nm This is the red band. Large amounts of absorption by chlorophyll occur, and most significant influence on photosynthesis (promotes budding and flowering.)<br />
720-1000nm There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.<br />
1000+ Totally infrared range. All energy absorbed at this point is converted to heat.</div>Misho
