We always need plants to embellish our lives, and plants need sunlight to take care of them. Water, sunlight and soil are essential for plant growth. Among them, sunlight is the most uncontrollable. We can’t control the natural light, but we can provide light to plants through technology.

If you are new to gardening, perhaps you are not familiar with the concept of plant lights. Don’t worry, I’ll introduce you to what plant lights are and what they can do.

Before I introduce you to plant lights, you need to know one concept: the full spectrum.

Full spectrum, refers to the spectrum curve that contains ultraviolet, visible and infrared light in the spectrum, and the ratio of red, green and blue in the visible part is close to that of sunlight, and the color rendering index is close to 100.

The spectrum of sunlight can be called full spectrum, the color temperature of sunlight is changing with the seasons and morning and evening time changes, so the spectrum of full-spectrum lights, should change color temperature successively with the change of time, simulating the natural light environment, in order to be more in line with the natural growth pattern of living things.

The plant light, it is a kind of light with full-spectrum lamp beads. It is not suitable for room lighting, and the human eye can not look directly at it for a long time. But for plants, it can be just the right amount of light for them to supplement.

Of course, the advantages of plant lights are not as simple as the full spectrum. You may be concerned about whether plant lights can really help your plants grow.

Nowadays, the market for plant lights is very well established. Plant lights are also becoming more and more versatile. Not only can they simulate sunlight, but they can also adjust the brightness, turn on and off at regular intervals so that the light can circulate. This also simulates the length of time that the sun shines, and you can adjust it to suit your needs.

There is no doubt that the plant lights do help plants grow. They are the perfect helper in times of lack of sunlight.
