There are three primary and integral components to replicating the sun’s perfectly balanced luminosity and radiance.

• Spectrum
• Uniformity
• Intensity

Spectrum

The visible spectrum of light is measured in PAR (Photosynthetic Active Radiation). What does this mean for artificial lighting? Different wavelengths within the PAR spectrum (400 nm – 700 nm) trigger different biological responses in plants physiology. Understanding this is key to designing and implementing lighting systems that effectively and efficiently drive those biological responses.

The two most useable spectral color wavelengths that drive plant photosynthesis are 450 nanometers (Blue) and 650 nanometers (Red). With these two spectrums combined at optimal peaks, we can optimize plant responses to efficiently drive growth acceleration.

Uniformity

We have covered the visual spectrum of light (PAR) and the important role it plays in driving photosynthesis but an often overlooked and sometimes completely ignored parameter is light uniformity.

Light uniformity is simply how well and evenly light is distributed to a growing area (canopy). Unequal light levels an indoor canopy will create different photosynthetic DLI’s (daily light integrals), which can create different plant growth responses.

The uniformity of the light environment has a large impact on the uniformity of the crop. Light regulates crop growth, plant development (including flowering), as well as how quickly plants use water.

When the light conditions in a growing area are not uniform, plants dry out at different rates, those under higher light often grow more and develop faster, and soon managing those crops with those that receive less light (and are smaller) becomes quite difficult.

Intensity 

We touched on the color of light and the equal distribution of light that plants need for optimal growth but what about the amount of light needed?

Plants use photons to convert light into sugars (food). These photons are quantified in PPF (Photosynthetic Photon Flux). This is a measurement of the total amount of PAR that is traveling from the light source in one second of time. This is an important metric to have but when that light hits the top of the canopy, some light becomes inactive. Therefore we need to measure PPFD (Photosynthetic Photon Flux Density). PPFD measures the amount of PAR that actually arrives at the plant (total usable light). This is a crucial metric in determining light intensity.

Light intensity or light quantity refers to the total amount of light that plants receive. It is also described as the degree of brightness that a plant is exposed to. In contrast to light quality (spectrum), the measurement of the intensity of light does not consider wavelength or color. Light intensity is a key factor that drives photosynthesis. The faster the photosynthetic rate, the faster the plant grows. The rate of photosynthesis is impacted immeasurably by light intensity. In other words, the brighter the light is, the bigger the yield will be.

With the plethora of commercial LED and legacy bulb fixtures crowding the marketplace, it can be confusing and overwhelming to say the least when choosing the ideal and best suited fixture for indoor cultivation. OCTO LED is here to light the path to improved, optimized and overall superior efficiency and efficacy.
