Do You Know That

Do plants need high Lumen/Lux?

Lumen/Lux is only for human eyes perceiving, not for plants growth. So if someone tell you to choose high Lumen/Lux grow lights, please tell them 'It's cool', then walk away XD. What's plants really need is enough PPFD.

What's the PPFD?
PPFD (Photosynthetic Photon Flux Density) is a measure of the number of photons in the 400-700nm range of the visible light spectrum (Photosynthetic Active Radiation or PAR) that fall on a square meter of target area per second.

Full Spectrum=Simulated Sunlight?

Not all wavelengths are good for plants. In general,  red+blue is enough for plants growth. Adding little green with be pleasant for human eyes, but High CRI ≠ High Efficiency. Red (660nm) should be strengthen when green added.

What's LCP? 
(Light Compensation Point) is the lowest photosynthesis demands of PPFD. Plants start to grow only when PPFD exceeds LCP. 

What's LSP?
When PPFD reaches a certain intensity, the photosynthetic rate will no longer be increased. That called LSP 
(Light Saturation Point).
