Types of Grow Lights

Ⅰ. The main types of grow lights

1. High pressure sodium lamp

This plant light has been around for a long time. It is also used in large greenhouses dedicated to growing vegetables and in large greenhouses dedicated to seedlings. Using a basic sodium lamp, light can travel in all directions. For the greenhouse, this is acceptable, but it is inconvenient for the house because it makes the eyes invisible.

2. Metal halide lamps for plants (MHD)

This is one of the subspecies of gas discharge lamps and is characterized by the presence of halogen vapor in the bulb. The rest of the structure is very similar to other gas discharge lamps. Similarly, at work, you need a special lamp with a control device, and is better than an electronic lamp. In addition, the protective glass on the plant flask must be strong, because the flask may explode due to high pressure.

3. Mercury gas discharge lamp (DRL)

The difference between such gas discharge lamps is that they can be used without additional equipment. Just screw them into a standard lamp holder connected to a 220 V network. The second point is that the bulb is made with a mirror coating, which allows you to form a directional flow of light without wasting energy on "illuminating the ceiling". The gas discharge mercury growth lamp is called DRLF. The red and blue parts of the spectrum have greater radiation intensity.

4. LED (light emitting diode) plant light

LEDs have become cheaper in recent years and are widely used for indoor plant lighting, such as LED grow lights for vertical farming. Production technology allows crystals to grow in a single color. Both wireframe and blue are available. But to illuminate plants, a certain wavelength is required: LED lights with a spectrum of 420-460 nm for blue and 630-670 nm for red.

They can be packed either in single crystal form or in strip form with a certain power. If we use "plant tape", then it contains red and blue LEDs in order to obtain the spectrum, which seems necessary. But usually in the LED light bar for growing plants, red light is dominant. It is good for plant growth and flowering. More blue is needed to form roots. Therefore, "standard" plant tape is not suitable for seedlings. There are also LED plant grow lights. Red and blue elements have been added to them to some extent. The only problem is that they are also sharpened for vegetation and flowering. For seedlings, they are ineffective: the root system is weak and the internodes are long. Therefore, for the growth of seedlings, it is best to make your own lights, or add blue.
