In order to accelerate the harvest of crops, enterprises often need to develop the light source and lamps needed for plant growth according to the light formula, in order to effectively improve the utilization of light energy and harvest the fruits. In fact, there are three main factors affecting plant growth: light quantity (light intensity), light quality (spectral range), and photoperiod. As long as the light source ratio is perfect, it can provide the best growing environment for plants.

However, in addition to the above three factors, Photosynthetic Photon Flux Density (PPFD) is more important for plant growth control. What is PPFD? It means how many photons hit a defined area(400~700nm) in one second. Plant has various species and different categories which have different PPFD requirements. The light intensity has valuable effects on the plant due to the different wavelengths. Therefore, if you can use the spectrometer to intuitively understand the light source quality of the plant lamp and master the spectral changes of different bands, you can adjust the artificial light source in time and achieve remarkable results.

Moreover, due to the emergence of plant factories in recent years, different types of plants are equipped with different types of plant light sources, which make the combination of factory and light source complicated. If the handheld spectrometer can provide different measurement methods, breaking the distance and space constraints, it can greatly improve measurement efficiency and flexibility.

Therefore, based on this market demand, we have also developed the PG100N Handheld Spectral PAR Meter, which can provide a variety of parameters for monitoring technical parameters — PPFD & PFD. It can measure different band ranges PPFD values to accurately grasp the plant growth status, and then adjust the light source to help improve the quality of plant. In addition, we specially designed the “detachable sensor head” for the measurement environment, which can be measured upright, lying flat, stand-alone and even synchronized multiple light sources.

If you can successfully control the plant growth of light source, you can successfully control the path of plant growth. LED lights applications are very extensive in plant lighting. How to detect the light quality to make plants growth effectively and healthy under the irradiation of light. UPRtek “PG100N Handheld Spectral PAR meter” will be your best chose.
