Typical usage of plant growth lamp

Plant lamps are used for indoor gardening, plant propagation and food production, including indoor hydrophytes and aquatic plants. Although most plant lamps are used in industry, they can also be used in the home.

According to the inverse square law, the intensity of light radiated by a point source (in this case, a bulb) reaching the surface is inversely proportional to the square of the distance from the surface to the source (if an object is twice as far away, it receives only a quarter of the light). This is a serious obstacle for indoor growers, and many technologies are used to use light as efficiently as possible. Therefore, reflectors are often used for lights to maximize light efficiency. Lamps or lanterns are moved as close as possible so that they have the same illumination and all light from the lamp falls on the plant rather than the surrounding area.

For example, incandescent lamps, fluorescent lamps, metal halide lamps (HID) and light emitting diodes (LED). Today, hid and fluorescent lamps are the most widely used lamps. Indoor flower and vegetable growers usually use high pressure sodium (HPS / son) and metal halide (MH) HID lamps, but fluorescent lamps and LEDs replace metal halides because of their efficiency and economy.

Metal halide lamps are often used in the vegetative phase of plant growth because they emit more blue and ultraviolet radiation. With the introduction of ceramic metal halide illumination and full spectrum metal halide illumination, they are increasingly used as exclusive light sources for vegetative reproduction and growth. The blue spectrum may induce a greater nutritional response in plants.
