- The plant growth's success formula - PPFD (photosynthetic photon flux density) What is PPFD? It means how many photons hit a defined area in one second. PPFD is the unit of measure, defined by μmol/m2/s or micro-moles of photons falling on a square meter per second. Plant has various species and different categories which have different PPFD requirements.
- Normally, Photosynthetically available Radiation (PAR) wavelength is 400nm - 700nm. The light intensity has valuable effects on the plant due to the different wavelengths.
+ Blue light (400nm - 500nm) - High absorption of chlorophyll and carotenoids influences the photosynthesis greatly.
+ Green light (500nm - 600nm) - Low absorption by pigments.
+ Red light (600nm - 700nm) - Improving plant flowering and germination.
+ UV light (400nm↓) - Inhibition of plant growth but good for plant pigment generation.
+ FR light (700nm↑) - Adjustments of flowering and germination.
- The Sensor head conforms with the JIS AA Class and DIN B Class Illumination requirements. Overall, the measuring process has a high speed, accuracy and stability.
- It is recommended for the horticultural Factory , Green house and City farmers.
