Why Blue Light?

BLUE-X® Shelters, a partially post-industrial recycled product, are fabricated from a partially transparent, substrate, blue-tinted polyester film (PET), (PART A). This produces amplified blue light which increases beneficial photosynthetically active radiation. Blue light increases diameter growth producing a visibly tapered self-supporting plant as nature intended. Tan, green, brown, or other opaque shelters decrease the blue light available to plants, thereby causing etiolation (thin elongated trunks).


The illustration below demonstrates why blue light is important to plants. Shown on the left is white light passing through a prism. The light is broken up into a range of wave lengths from the 390 nm of violet to the 780 nm of red. This represents all the light potentially available to plants.

On the right, sunlight is shown passing through a leaf placed in front of the prism. Behind the prism dark bands in the spectrum are revealed between 390 and 500 nm and between 650 and 740 nm, indicating that chlorophyll has absorbed light of these wavelengths. BLUE-X® takes advantage of this phenomenon by providing increased amounts of blue light to your plants.


The second illustration represents the results of a study done in Germany comparing the light generated by BLUE-X® Shelters and white light (Weisse Folie). Between the spectrum numbers 300 to 530, and 680 plus, the light emitted from the BLUE-X® is greater. Conversely, the light least used by plants, between the spectrums of 530 and 650 is lower with BLUE-X®.

UV light is known to be harmful to plant growth and to damage DNA. BLUE-X® Shelters are designed to block transmission of a significant amount of this harmful UV light. Recent scientific evidence has also shown that blue light actually helps repair the damage caused by UV light.
