PowerVEG T5 4' 420 Blue Grow Light

The name “420” references the area of the light spectrum produced by this lamp. The PowerVEG 420 is a true VEG light for indoor growers. PowerVEG 420 provides a spectrum that is crucial for plant growth during the vegetation cycle, focusing all spectral energy at 420 nanometers. This high UV A spectrum adds the nutrient values that are vital for the growth. Combined with the spectrum provided by the FS+UV fluorescent grow lamps, the PowerVEG 420 maximizes the initial growth process for vegetation through tighter internodal spacing, stomatal opening 10 times greater than red light (feeding tube of plant), stronger root growth, chlorophyll A, Lutein, Zeaxanthin and Beta Carotene.
