Led light for indoor growing

The role of light in plant growth.

How do we measure light for plants?

PAR
photosynthetically active radiation

Spectral range (wave band) of solar radiation from 400 to 700 nanometers that plants are able to use in the chemical process of photosynthesis. PAR’s irradiance is measured in energy units W/m2.

PPFD
photosynthetic photon flux density

Chemical reactions of photosynthesis depend closely on the amount of photons (in the 400-700 nm range) received by a surface for a specified amount of time. PPFD is measured using μmol m−2s−1..

VEGETATIVE PHASE
400 – 520 nanometers

This range includes blue light in order to prompt the plant’s vegetative phase during which chlorophyll absorbs energy from light, impacting photosynthesis and stimulating plant growth and leaf production.

FLO WERING PHASE
610 – 700 nanometers

This range includes red light and is the peak period of light absorption, affecting the process of blooming and flowering, leading to fruit.

MICROGREENS
FRESH, NATURAL, FAST

On-site microgreen farming provides the perfect opportunity to communicate relevancy in the changing retail landscape where consumers demand high-quality, fresh, sustainable produce.
