Sunmaster 400W Dual Spectrum

The Sunmaster 400W Dual Spectrum is a different HPS grow light designed to cater for all periods of plant growth. Unlike regular HPS lamps that are designed to emit only red light for the flowering period, the Sunmaster 400W Dual Spectrum has been modified to emit enough blue light to support both the vegetative process, the flowering process and the fruiting process.

Dual-spectrum bulbs are becoming more and more popular after many positive reviews from gardeners, because they provide what is needed for the entire development period. Dual spectrum technology not only reduces cost by eliminating the need to purchase separate lamps for different periods, but also provides economy and efficiency for each period of your plant's development.
