The formation of chlorophyll in all plants requires photosynthesis, and its blue and red wavelengths play an important role in plant growth. Blue waves stimulate the growth of leaves, while red promotes flowering.

Plants have certain requirements for light quality. Incandescent lamp is the most common one, which emits strong warm light interwoven with yellow and red, while halogen lamp is a cool light beam. It should be noted that it should not be placed near the light source. The heat it emits will burn the blades, and there should be a certain distance between them. If it is 60 cm away from the incandescent bulb.

As long as the growth conditions of water, carbon dioxide and chlorophyll are guaranteed, ordinary fluorescent lamps are ok.

Now there are fluorescent tubes specially used to cultivate plants instead of sunlight on the market.

Go to a store that specializes in selling aquarium equipment. There is a fluorescent tube used to grow aquatic plants. The color of the light it emits looks like sunlight to the naked eye. Imported 30W 40 yuan costs 100 yuan each, while domestic products are much flatter, and the flattest is around 8 yuan. Even if these fluorescent lamps are usually used at home, the colors produced will make people feel very comfortable, but the price is always more expensive than ordinary fluorescent lamps.

The disadvantage of plant (fluorescent) lamp tube is that the effective irradiation distance is only less than 500mm, but the attenuation is great and the utility is greatly reduced. There are also metal halogen chandeliers and mercury chandeliers, which have large effective lighting distance and high power, and are more suitable for large-area long-distance use.
