Horticulture Metrics: background Information

• Plants are sensitive to a similar portion of the spectrum as is the human eye. This portion of the

light spectrum is referred to as photosynthetically active radiation or PAR, namely about 400 to

700 nanometers in wavelength. Nevertheless, plant response within this region is very different

from that of humans.

• The human eye has a peak sensitivity in the yellow-green region, at 555 nanometers. Plants, on

the other hand, respond more effectively to red light and to blue

Important Horticulture metrics

• Photosynthetic Photon Flux or PPF measures the “photosynthetically active photons emitted by a lighting system per second”. This measurement is expressed in μmol/s. This is the “equivalent” of lumens for plants

• Photon Efficacy or PPF/W refers to how efficient a horticulture lighting system is at converting electrical energy into photons. This measurement is expressed in μmol/J

• Photosynthetic Photon Flux Density or PPFD is a measurement of the number of photosynthetically active photons that fall on a given surface each second. It is expressed in μmol/mj/s

• Day Light Integral or DLI is a cumulative measurement of the total number of photons that reach a given surface during the daily photoperiod. DLI is expressed in mol/m2/d

• Rule of thumb: 1% increase in DLI translates in 1% increase in plant growth yield

What do LEDs offer in horticulture market?

• Efficacy:

Efficacy can be twice as good as with HPS lamps (>3.0 mmol/J)

• Reliability:

Fixture-level reliability is limited by driver and other

Components

• Flexibility:

Large range of visible spectrums can be covered.

Why Horticulture Lighting?

Horticulture Lighting - Photosynthesis process

• Plants produce organic matter from air, water and light through photosynthesis

• Gas and water exchange take place through tiny holes in the plant leaves called stomata

• Photosynthesis takes place in mesophyll area inside the leaves

• Mesophyll cells contain chloroplast where the photosynthesis occurs

• Chlorophyll pigments in the chloroplast are responsible for the light absorption
