Grow Light Overview

GROW LIGHT OVERVIEW
Plants use the visible light spectrum from seed germination all the way through budding and flowering

3 STAGES OF GROWTH

The “Blue” spectrum is used for seeding and vegetative growth (stem and leaf growth
The “Red” spectrum is used for budding and flowering

GROW LIGHT DEFINITIONS

PAR (Photosynthetically Active Radiation)

The narrow band of light that plants see and need to grow

PPF
(Photosynthetic Photon Flux)

The amount of light particles that come out of the light

PPFD
(Photosynthetic Photon Flux Density

The amount of light particles that actually reaches the plant

* The higher the number, the quicker and stronger the plant grows *

LUMENS VS PPF

LUMENS

The brightness of a light. Plants do not detect brightness.

PPF (Photosynthetic Photon Flux)

The total amount of light in the PAR spectrum released by a light each second.

The brightness of a light. Plants do not detect brightness.
