Photosynthesis outputs peak between 435 nm and 680 nm. Our 6400K T5HO lamps have a spectral distribution with relative intensity peaks at 435 nm and 615 nm. These are ideal for both propagation and longer term growth. This equates to very little wasted light energy in terms of plant growth and production. Unlike conventional fluorescents, plants grown under
