Sunmaster Sodium Bulbs
Sunmaster Sodium Bulbs product details:
Sodium lamps are used for the flower-phase of plant growth when the plants need lots of red spectrum light which these bulbs put out. You can use sodium bulbs for vegetative growth as well but a metal halide blue spectrum lamp would achieve much better results.
