Is It Better to Choose Full Spectrum or Red and Blue Spectrum for Plant Growth Lights?

The growth light is a new LED light to the extra lighting supplement for the plants, reducing the influence of the weather on the photosynthesis of the plants. Resulting in the phenomenon of leaf disease in the growth environment of the plants. But for most growers, there are a variety of spectra and is it better to choose the full spectrum or red and blue light?

Firstly, growers need to know that red light can promote plant flowering and fruit, and blue light can promote plant growth of seeds and leaves. Researchers found that the range of the wavelengths studied was specifically based on the effects of sunlight on plants. There are mainly red light bead, blue light bead, and full spectrum lamp bead and the red light bead is mainly to regulate the plant photoperiod, affecting the plant flowering and fruit. However, blue light mainly affects the movement of leaves and plastids, promotes the growth of stems and leaves, and inhibits the flowering and fruit of plants to a certain extent.

There are only two spectra of red and blue light in the red-blue growth light, while the full-spectrum plant light simulates sunlight, and the spectrum is the same as sunlight, emitting white light. Both spectrum can affect the filling light and promote the plants' growth.  However, it is necessary to choose the proper spectrum for different plants.

For example, growers are planting lettuce, and the lettuce is a plant that takes stems and leaves for human use, grower need to choose a light-filling program that simulates the quality and yield of stems and leaves. So it can increase the proportion of the blue lamp beads in LED plat lights. Another example: is tomato planting, growers are planning to plant large and round, healthy and green high-quality tomatoes, and they need to simulate its flowering and at this time, LED plant lamp red bead ratio can be appropriately increased. The ratio of red and blue lamp beads is roughly between red: blue = (6--9):1, according to the needs and uses of different plants, choose different lamp bead ratios. Sometimes a small amount of green light beads are mixed in LED plant lights, whose main role is to adjust the comfort of the light and protect the naked eye.

For flowering and fruiting, it is best to choose a red-blue LED growth light when it needs to be colored. It is great to choose full-spectrum for the leaves vegetables, which promotes flowering and fruit and increase production. If growers want to plant at home, it is best to choose a full-spectrum LED luminaries, because the light of the red-blue plant lamp is pink.

Choose full-spectrum plant or red-blue ratio plant light. Growers specifically look at the spectral needs of plans, light efficiency, power, growth stage and cycle and other factors to decide, to find the formula solution suitable for plans is the most important.
