Technology

A Layer of Light

UbiGro® is an innovative new product that empowers greenhouse growers to control light quality, allowing plants to get the most from sunlight. Enabled by patented quantum dot technology, UbiGro uses fluorescence to increase photosynthetic efficiency to improve fruit and flower production without wires or electricity. This increases crop yields for the grower, which means more revenue for the farm.

Understand the Spectrum

How Color Affects Plant Growth

Relative photosynthetic efficiency is dependent on the wavelength of light. Wavelengths between 600-650nm are the most efficient for photosynthesis. The ‘action spectrum’ illustrates the differences in relative photosynthetic efficiency by wavelength. See our White Paper for a more in depth look at this topic.

By shifting UV and blue to orange and red light, UbiGro shifts the sun’s spectrum towards the maximum photosynthetic potential in plants which in turn improves crop yields.

An Enhanced Spectrum

UbiGro glows when illuminated with sunlight. Unlike shade cloths, spray coatings or colored films that filter light, our technology converts short-wavelength photons (blue and UV) to longer wavelength photons (orange and red). 

As a luminescent layer, UbiGro empowers growers to optimize the sunlight in their greenhouse by converting excess photons of the solar spectrum while preserving colors critical for plant development.

Light Diffusion Affects Plant Growth

A more uniform distribution of sunlight throughout the greenhouse canopy will increase overall photosynthesis and production. Diffuse scattering of sunlight is an effective way to achieve a more uniform distribution.

Direct light from the sun is strongly absorbed by the upper canopy leaving the lower canopy shaded. Diffused light avoids this issue: there is less shading by the upper canopy, higher light levels in the lower canopy, and the net result is better overall crop growth and plant productivity.

Diffusion

What is light diffusion? Simply put, it is the scattering of light. Photons from the sun get scattered in all directions as they pass through our layer of quantum dots. Much like the dimpled reflector of an HID grow light that scatters the photons of light from the bulb, our UbiGro film scatters photons from the sun.

The quantum dots used by UbiGro have great diffusion properties and when sunlight passes through UbiGro, these photons are not only having their wavelength changed to be more orange and red but also scattering them, making them penetrate deeper into the plant canopy to increase overall production.

Why do Quantum Dots Glow?

QDs & Photons

UbiGro glows. The product is designed to glow at the color that helps plants accumulate biomass as fast as possible. What is happening within UbiGro to make this happen? The process is called ‘photoluminescence’. Photoluminescence is when a material absorbs a certain color of light and emits or ‘glows’ a different color. QDs in UbiGro film glow incredibly bright because they are so efficient at absorbing UV and blue light and emitting orange or red light.

What does photoluminescence look like at the nanoscale? 

Photons are particles of light. When a photon of UV or blue light hits a quantum dot, the light energy is absorbed, and almost immediately, a photon of a new color is emitted. Thanks to sunlight in a greenhouse, this process is occurring more than a trillion times per second in just 1ftof glowing UbiGro – which is why plants below UbiGro enjoy an optimized sunlight spectrum.
