The PowerVEG 420 is a true VEG light designed especially for indoor
growers. The lighting spectrum provided by the PowerVEG 420 is crucial
for vegetative plant growth and focuses all lighting spectrum energy at
420 nanometers. The name “420” is a reference to the physical area of
the lighting spectrum produced by this lamp. Combined with the lighting
spectrum provided by the FS+UV fluorescent grow lamps, the PowerVEG 420
maximizes the initial stages of growth 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.
