Dangers of designing with a variable spectrum- you are better off using proven spectrums instead.
Do you really want to create your own light spectrum or try to create your own light recipe with variable spectrum technology?
…Developing a growth spectrum
When developing a new growth spectrum, one has to know the goals and aims:
How will the plants respond to this spectrum?
Who will benefit from this type of growth performance?
Unless you are committed to years of research, and investing millions, as Valoya has, we suggest that you instead use tried and true growth spectrums because:
Spectra development includes changing the R:FR ratio, changing the B:G ratio and considering the correct balance between all wavelengths
The amount of FR in a spectrum affects elongation growth and flowering of many species.
When the red peak was moved from 630 nm to 640 nm and further to 650 nm, the amount of FR increased which was reflected as longer flowering stem in lettuce variety ’Multiblond’.
Let’s review a well known spectrum, such as Valoya’s NS1 spectrum. It is white, sun like spectrum. It enhances compactness and does not promote flowering. It contains also some UVA and some far-red irradiation.
GOOD DAY SUSHINE
Valoya NS1 creates a light environment similar to sunlight.
The LightDNA B & R-series fixtures offers a 2 channel system which comprises the main light spectrum (NS1) & a complementary tuning spectrum (far-red)
Enables good spectrum replication of a clear sky at noon & replication of dawn / dusk
Also gives control of the red/far red ratios to enhance the flowering cycle, as well as decrease time to harvest.
