Seed Starting, Grow Lights

Seed Starting, Grow Lights Article

Grow lights are electric lamps designed to promote plant growth by emitting an electromagnetic spectrum appropriate for photosynthesis. It does this by mimicking the light spectrum from the sun, allowing indoor growth with outdoor conditions.

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 should be done with red/orange spectrums. The lights can be bought by spectrum colour specifically, or some companies such as Sylvania Grolux 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 flow of current flowing to the light. This is required because of the high intensity of the light that is necessary to produce something akin to sunlight.

Lamp types used as grow lights include high-intensity discharge lamps, fluorescent lamps and LEDs. Grow lights are most used for indoor gardening, including indoor hydroponics and aquatic plants.

The most widely used lights for professional indoor flower and vegetable growing are HPS (High Pressure Sodium) and MH (Metal Halide). These are types of HID or high-intensity discharge lamps.
