Why people say that plant lights are a hoax?

Now greenhouse planting is becoming more and more common, including flower greenhouse, vegetable greenhouse and fruit greenhouse. Greenhouse can provide the most suitable environment for plant growth. Water, temperature and fertilizer can be well controlled artificially. For the sunlight required by plant photosynthesis, people have studied plant lighting and used it to replenish light for plants.

But many people often say that plant lights are useless at all. It's a scam! Is the plant lamp useful? How much do you know about plant lamps?

According to the natural law of plant growth and the principle of photosynthesis by using sunlight, plant lamp uses light to replace the sun to provide light for plant growth. Plant lamps are generally used when the light intensity and illumination time are not enough, such as cloudy, rainy or haze days. If plants with long sunshine can not meet the growth needs, plant lamps can be used to supplement light.

When using a plant lamp to replenish light for plants, we must first distinguish whether the plant is a long sunshine plant or a short sunshine plant. Short sunshine plants cannot replenish too much light, otherwise it will affect flowering and fruit. For long sunshine plants, we need to know the required lighting time and intensity. Secondly, we should choose and use the right plant lamp in the right place. For example, when planting green plants on the balcony or plant flower rack at home, we can choose the lamp tube type plant lamp to use the plant lamp, and the plant lamp with lower power can meet the demand. However, if we fill the light for the plants in a large-area greenhouse, we need to choose the flying saucer type, bulb type or industrial and mining type plant lamp to fill the light for the plants. The lamp tube type plant lamp has low power The irradiation area is small, so it will not be effective when used in the greenhouse.

Shandong vegetable association used light factor lighting plant lamps to fill the light for tomatoes. In the absence of haze days, after experiments, tomatoes increased by 12.7% per mu, and were listed seven days in advance, in which all kinds of nutrients were increased. The light filling experiments of nectarine, zucchini and cucumber were also carried out, and good experimental results were obtained.

Therefore, the plant lamp is not a scam. A large number of experiments have proved that it is effective for the growth of plants, but we should choose the appropriate fill lamp and use the correct method
