Horticultural lighting in Riverside, CA

What Is Horticulture Lighting?

Horticulture lighting is the method for promoting plant growth by artificial lighting fixtures when natural light is lacking.

Professional horticulture lighting is not just about providing sufficient light for plant growth through the improvement of photosynthesis, but also about helping plants to produce a more beautiful flower, better shape of leaves and more fruit as well as shorten or lengthen a particular growing phase.

For professional horticulture lighting, the right customized recipes are necessary for optimization of plant growing on purpose. The particular requirements of different plants in each growing phase and each part of plant organs determine which lighting recipe is better for optimize growth.


Aside from the variables consisting of temperature, humidity, water, oxygen, carbon and nutrients, unique characteristics of lighting also play an important role in controlling plant growth. The light intensity, spectrum and duration influence plants' morphology, growth, fruiting and flowering.


Plants can transform light energy into chemical energy by photosynthesis. Plants need to absorb special light spectra emitting in order to generate necessary elements, such as chlorophyll, anthocyanin, carotenoid and phytochromes, within it's organs for growing. A professional horticulture lighting recipe should optimize the spectrum of light source to fulfill the plants needs for photosynthesis in order to maximize the growth speed and minimize the electrical energy consumption simultaneously.

PAR: Photosynthetically Active Radiation

Photosynthetically active radiation, also called PAR, stands for the spectral range of solar radiation from 400nm to 700nm. It specifies the light the plant needs to sustain photosynthesis. In this range, plants' photosynthetic organisms are able to absorb light in the process of photosynthesis.

PPF: Photosynthetic Photon Flux

Photosynthetic photon flux (PPF) is a measurement that identifies the overall amount of photosynthetic active radiation (PAR) a light produces. It values all photons from 400nm to 700nm based on the plant's photosynthetic response.

PPFD: Photosynthetic Photon Flux Density

Photosynthetic photon flux density (PPFD) is an additional measurement that provides the same information as PPF. It also represents the photons in the spectral range of 400nm to 700nm. While the distinction between them is that PPF measures the number of photons that get off from a light source. On the other hand, PPFD refers to how many photons drop on a surface area in square meters.
