Grow Light Bulbs

Different light spectrums are used for the different stages of plant growth. The initial vegetative stage requires blue spectrum of light, whereas the later "flowering" stage is usually done with red–orange spectrums. The lights can be bought by spectrum colour specifically or can be purchased to produce a full spectrum bulb which caters for all stages of growth.

The light is usually used in conjunction with a reflector, to control and intensify the light emissions, and will include an electrical ballast to control the current to the light. This is required because of the high intensity of the light that is necessary to produce something akin to sunlight.
