Product description
PAR light (Photosynthetically Active Radiation)The growth potential of a plant can be measured by the amount of PAR light it receives. COâ‚‚ and nutrient water are of course important, besides which PAR light is the main component for photosynthesis.
In the past, horticulture often measured with a LUX meter. It has now been discovered that the amount of LUX says nothing about the growth potential: it is only part of the light that is important.
A LUX meter measures the ‘total amount’ of light. Ideal e.g. to measure whether a workplace or desk is sufficiently illuminated to carry out work, but useless for determining ‘growing light’. A PAR measurement measures the light spectrum between 400 nanometres and 700 nanometres. Actually, a PAR sensor measures the ratio between the number of photons hitting a surface in 1 second and the surface in m2.
The quantity of measurement is: µmol/(m2 s-1). So measuring PAR light is important because it says something about a plant’s growth potential. Not only when growing under sunlight, but of course also when using artificial light (model LX5100/LP471PAR02).
