Crop protection companies, specialized in developing herbicides, fungicides and insecticides for agricultural crops benefit from advanced LED lighting that develops strong, vital plants in indoor conditions. These herbicide and metabolic studies demand outdoor conditions to be replicated in greenhouse or growth room settings. The key element is light which contains colors from the entire light spectrum, including outside the PAR area. Valoya has developed advanced LED lighting such as its proprietary NS1 and NS12 spectra, specifically for these purposes. The spectra in question are a close sun match and appear white to human eyes enabling researchers to spot the smallest of differences on plant leaves and stems ensuring a precise visual inspection.
