(HPS+Metal Halide) Cool

Sunmaster's COOL grow lamps were developed to drive strong vegetative growth. For indoor growing operations requiring 100% artificial lighting, Sunmaster COOL lamps lead the industry with regard to total �mol output in specific spectral ranges to promote strong vegetative growth.

University and 3rd party tested, approximately 50% of the spectral energy of Sunmaster's COOL lamps are found in the blue/violet range between 380nm and 495nm. Partner Sunmaster's COOL lamps with 'SUPER' lamps for the flowering period of the plant growth cycle and �FINISH� lamps at the end of the plant growth cycle in order to maximize yield.
