Recently, an organization has given us a big hint by using different spectra and different intensities to grow red lettuce. Control the Grow Lights and you will be pleasantly surprised.
The group's experiment went like this: Using two different spectrum lights, each with three different intensities, was used to grow red lettuce.
The only difference between the two lamps is that one contains enhanced UVA and blue light.
It turns out that:
1. The stronger the light intensity, the higher the anthocyanin of the lettuce and the redder the color.
2. Contains enhanced UVA and blue light spectrum also shows enhanced effect on anthocyanin and red
In fact, as early as 2009, an experimental paper¹ stated that UVA and blue light can increase anthocyanins, while far-red and green light have opposite effects.
The difference is that the 2009 experiment was done through with separate supplemental lights, this time by combining useful and other wavelength lights into a single grow light.
These experiments all proved the influence of LED intensity and spectrum control on vegetables. Most of the plant lights on the market currently have non-adjustable spectrum and are not targeted to certain plant. Therefore, users can only obtain the effect by purchasing new lights separately, which will increase the additional costs,
So a better approach is to directly own a product like Ultra Plant™ with 100% adjustable spectral intensity, giving the grower maximum freedom to develop the best lighting strategy .
