Dual Spectrum Bulbs
The vast majority of a Dual Spectrum Grow Lamps output is in red light. However the beauty of a Dual Spec is that it also delivers enough blue light to enable you to use it continually though both the Vegative and Flowering stages and saving on the need for 2 separate bulbs. Available in 150 watt, 250 watt, 400 watt, 600 watt and 1000 watt.
