1. Grow Light Spectrum Chart
The above chart shows the PAR range - the spectrum of light plants use for photosynthesis. Grow light spectrum charts like this include both the PAR range and other spectrums as it's been discovered that wavelengths outside of the PAR range (UV Light and Infrared) are also helpful for plant growth.
2. What is Broad Spectrum Lighting?
Broad spectrum lighting - often referred to as full spectrum lighting, means the complete spectrum of light given by sunlight. This means wavelengths of broad spectrum lighting include the 380nm-740nm range (which we see as color) plus invisible wavelengths too, like infrared and ultraviolet.
3. Specific grow light spectrums and their application in horticulture
UV Light Spectrum (390-405 nm)
Around 10% of the sun's light is ultraviolet. While the benefits of ultraviolet light use in horticulture are still being researched. Small amounts of ultraviolet can have beneficial effects for plants on color, nutritional value, taste, and aroma.
Blue Light Spectrum (450-460nm)
Blue light spectrum is widely responsible for increasing plant quality - especially in leafy crops. It promotes the stomata opening - which allows more CO2 to enter the leaves. Blue light drives peak chlorophyll pigment absorption which is needed for photosynthesis.
Green Light Spectrum (515-525nm/550-570nm)
Green wavelengths have been somewhat written off as less important for plant photosynthesis given it's (in)ability to readily absorb chlorophyll compared to red or blue light spectrums. Nonetheless, green is still absorbed and used for photosynthesis; in fact, only 5-10% is actually reflected - the rest is absorbed or transmitted lower down.
Red Light Spectrum (655-665nm)
Red light is known to be the most effective light spectrum to encourage photosynthesis as it's highly absorbed by chlorophyll pigments. In a word, it sits in the peaks in chlorophyll absorption. Red light wavelengths (particularly around 660nm) encourage stem, leaf, and general vegetative growth - but most commonly, tall, stretching of leaves and flowers.
Far-red Light Spectrum (730-740nm)
Far-red can be very useful to promote flowering, and in certain plants, increase fruit yield. In short-day plants, which rely on longer periods of darkness, 730nm can be used at the end of a light cycle to promote flowering. Many growers are experimenting with interrupting the dark cycle with bursts of red light to boost growth and flowering.
