A very popular all round lamp that offers improved spectrum but also retains its high lumen output. The improved spectrum and extra levels of blue and red light make it excellent for vegetative or flowering growth. This improved metabolic function (Chlorosynthesis, photosynthesis, etc) giving good health and a green colour. The large levels of yellow / orange inherent in the high pressure lamp ensures the plants gets lots of energy through photosynthesis for vigorous growth and high yields.
