The CULTIVA WALL series is the answer that Igniagreen and Ignialight have provided in response to market demand for a dedicated solution for lighting green walls where there is a lack of natural light.
Plants have a number of differentiated lighting requirements with respect to the lighting needs people have to see green walls properly. That is why it is important to consider the following concepts:
1.- Plants are photosynthetic organisms so they need light to grow. This light is absorbed by a series of photosynthetic pigments (chlorophyll A and B, carotenes, phycocyanins, phycoerythrins, etc.), with the first two being the most important in photosynthesis. Of all the radiation emitted by the sun, it is considered that for photosynthesis purposes, plants only use light between 400 nm and 700 nm, corresponding to the visible spectrum and known as PAR light (Photosynthetically Active Radiation).
2.- People need light to see. Luxis used to measure the illuminance of a given space, expressed in lumen/m2. This unit of light output takes the human eye as a reference, with a maximum of 555 nm (green color). By contrast, the maximum point of absorption by plants is between 400 nm – 450 nm (bluecolor) and 650 nm – 700 nm (redcolor), and the minimum is 550 nm (green color).
