Photosynthetically Active Radiation (PAR) Spectral range between 400-700nm for which photosynthesis occurs Often referred to as a unit, but it is not. Can refer to either: PPF – Photosynthetic Photon Flux (μmol·s-1) PPFD - Photosynthetic Photon Flux Density (μmol·m-2·s-1) PPFD being the common reference

Measurement Standard PPFD measurements are performed on a 4x4’ grid at the manufacturer’s recommended height. Measurements can go up to 10x10’ grid. Measurements are performed with a handheld meter, which is why PPFD is commonly used as a performance metric rather than PPF Unfortunately many of these tests can be center-weighted, which can falsely skew data.

Red and Blue Chlorophyll a & b Chlorophyll refers to the pigment used to absorb radiation for photosynthesis. Chl a efficiently absorbs red while Chl b efficiently absorbs blue. These absorption peaks were the reason why 440-450nm and 660nm are quoted throughout the LED horticulture industry.

Слайд 21


Red and Blue Studies were derived from in-vitro on green algae. Higher order plant organisms differ in response. In vivo, the probability of a pigment absorbing light absorption depends on: the specific protein that the pigment is bound to the orientation of the pigment-protein complex within the cell the forces exerted by the surrounding medium on the pigment-protein complex.

Which LEDs to choose? Horticulture market has no set methodology as to what is right and what is wrong. Approaches include: Red and Blue only Many discrete colors from UV to IR White only with higher CRI for the red content White with supplemental colors (Red and Blue) Customer is the expert as there are many recipes on the market XP and XQ footprint offers the most versatility
