Are Grow Lights Full Spectrum or Red and Blue?

Plant growth lights can replace sunlight to supplement light for plants to promote plant growth. They can be used when planting vegetables, fruits, and flowers. They can not only promote the growth of seedlings, but also promote flowering and fruiting, increase production, and advance the market.

There are many types of plant growth lights, and the spectrum includes full spectrum and red and blue light spectrum. Is the full spectrum or red and blue spectrum better for plant growth lights?

1. The difference between full-spectrum plant growth lights and red and blue light

After research on the absorption and utilization of sunlight by plant growth, it is found that the absorption and utilization of red and blue light in sunlight by plants is relatively large. Red light can promote plant flowering and fruiting, and blue light can promote plant growth, so in the later research on plant growth lights, people developed plant growth lights with red and blue spectrum.

This kind of light has a good effect on the growth of plants, and has a better effect on crops and flowers that need to ensure the color. Moreover, the red and blue light can be matched according to the needs to obtain a spectrum suitable for plant growth.

There are only two spectrums of red light and blue light in the red and blue grow lights, while the full spectrum grow lights simulate sunlight, and the spectrum is the same as sunlight, and the light emitted is white light.

Full-spectrum plant growth lights and red and blue light have the effect of supplementing light for plants to promote plant growth, but different crops should pay attention to choosing the right one when choosing the spectrum.

For flowering and fruiting, crops and flowers that need to be colored, red and blue light can be used to color, promote flowering, and increase yield. For leafy crops, full-spectrum plant growth lights can be used.

If you grow plants at home, choose a full-spectrum grow light, because the light of red and blue grow lights is pink, and people will feel dizzy, nauseated, and uncomfortable if they are in this environment for a long time.

2. The phenomenon of using led grow lights

The LED red-blue plant growth light adopts the ratio of red lamp beads and blue lamp beads, mainly because a single LED chip cannot maturely "integrate" light of different bands on the same chip.

Since 2013, LED chips and packaging processes have become more and more mature, and full-spectrum LED grow lights have begun to appear in the market, but the market's response has been tepid.

Due to the disproportionate cost of expensive lamps, electricity costs and crop output, as well as the limited level of agricultural modernization in China, the acceptance of LED grow lights is low, and the use of LED grow lights is also mostly used in modern vertical farms for vegetables and fruits planting.

The turning point appeared from 2018 to 2020. The industrial hemp market was gradually liberalized in North America, and some other countries will also put the release of industrial hemp cultivation on the agenda.

Crops with high economic added value such as industrial hemp "give" new life to plant growth lamps. Industrial hemp grow lamps have become popular, and many lighting companies have entered the market.

Compared with the traditional plant planting supplementary light scheme, the advantages of led cannabis plant lights are obvious. Industrial cannabis planting will inevitably bring LED plant growth lights for a while, but the heat will fade, and LED plant lighting will still fall into the down-to-earth companies.
