"Using Variable Spectrum Luminaries Allows us to Grow a Wide Range of Plants"

Bringing food closer to consumers is no longer an option but rather a necessity, given the strain traditional agriculture and transportation place on the environment.

Bringing food closer to consumers is no longer an option but rather a necessity, given the strain traditional agriculture and transportation place on the environment. Czech grow tech company GreeenTech teamed up with Hungary’s Tungsram to provide vertical farming solutions that pave the way for sustainable crop production.

Prague-based GreeenTech was born out of this realization. The company specializes in the research and development of hydroponic technologies to be used in container farms and vertical farms set up in buildings. Established in 2000, the business aims to enable people to grow agricultural crops anytime and anywhere in the world.

They are involved in developing innovative solutions for the local production of leafy vegetables, herbs, and small fruits through their own hydroponic cultivation technology complete with an IOT control system created in cooperation with Siemens. The uniqueness of the solution provided by GreeenTech lies in the development of tailor-made hydroponic farming technology.

Finding the perfect lighting solution
"Hydroponic systems are soil-less, water-based farming processes. The technology is based on growing plants in a controlled environment where crops are fed nutrient-rich water. Crop cultivation takes place in an enclosed growing space, where sensors control conditions such as humidity, temperature, or light cycle. The result is quality crops that have not been subjected to treatment with pesticides and herbicides and the farm uses about 90% less water than conventional agriculture," the GreeenTech team explains.

Given that crops are not exposed to natural light, selecting the right lighting solution in these farms is of utmost importance. GreeenTech’s quest for the best lighting solution provider-led them to Tungsram, whose variable spectrum LED luminaries proved to be the perfect match as the light sources have been designed and created only for the purposes of a growing container.

“We were searching for a lighting solution and we realized that Tungsram’s luminaries and the automation solutions provided by them are ideal for our needs because they are well suited for research purpose. Using variable spectrum luminaries allows us to grow a wide range of plants. In addition, customers have a high degree of flexibility in deciding what kind of plants they want to grow or in switching from one crop to the other,” said Karolína Pumprová, CGO at GreeenTech.

LED lights
"Our four-channel LED lights offer the highest performance in their category and are extremely easy to install," the Tungsram team says. "The luminaries are controlled remotely and allow users to adjust the color spectrum and light intensity independently for each growing rack, which is a game-changer for large-scale urban farms."

In addition to the lights, Tungsram also provided a tailor-made lighting design with the help of the company’s engineers and designers. "Variable spectrum luminaries are a powerful tool for growers in terms of adopting a “dynamic light recipe approach,” which is a rather unique offering in the market."

Compatible with software
“Another factor that weighed heavily in favor of Tunsgram was the fact that the lighting solution developed together with them was compatible with the software and system we already had in place,” said Milan Souček, CTO at GreeenTech.

GreeenTech will use the Tungsram luminaries at the expo in Dubai, which will run from September through March. The cultivation container will be set up in a restaurant and the plants will be used in the restaurant. As part of a cooperation with the Technical University in Prague, Tungsram lights will be installed at a small hydroponic farm set up by GreeenTech where students will be conducting research and testing.

Valoya Launches Two New Greenhouse LED Grow Lights

Valoya, the research-driven manufacturer of horticultural LED grow lights has expanded its RX-Series line of greenhouse LEDs with two new models – RX500 and RX600

Valoya, the research-driven manufacturer of horticultural LED grow lights has expanded its RX-Series line of greenhouse LEDs with two new models – RX500 and RX600. The new models are higher power, higher efficiency versions of the existing RX400 model, and can be used as true 1-to-1 HPS replacements. RX500 and RX600 produce up to the staggering 1700 µmol/s of uniform light output. They have been designed to be robust and compact, producing minimal shading over the canopy. With an Ingress Protection rating of IP65 (wet location) these luminaires are completely dust tight and can withstand spraying with water jets from any direction. The high light intensity they produce enables them to be positioned high above the canopy, as much as 4 meters above it.

Valoya’s LED technology is proprietary and great efforts have been taken to create LED luminaires that last long and sustain the same light spectrum over their entire lifetime. RX500 and RX600 typically last 50000 hours whereby the intensity drops to 90% after about the 36000-hour mark. The spectrum decays evenly ensuring the grower will be getting the same plant performance and will not have to change the growth protocol over time.

In transitioning from HPS to LED, growers have to develop new growth protocols quickly. This is where Valoya’s team of biologists will provide support and expertise based on over 600 plant trials conducted in over 10 years. This means growers will hit the ground running after their LED upgrade and will see improvements in their plant performance right after it.

The new models are available with most of Valoya’s patented spectra such as SolrayÒ (sunlight replica) and AP673L (vegetative growth). All of Valoya’s spectra can be used as sole source lighting in no sunlight environments as well as together with sunlight. They have been tested on over 300 plant species/varieties and we will gladly share this data with growers to help them get the most out of their plants.

RX500 and RX600 are heavy-duty, greenhouse luminaires designed to produce high and uniform light output over a long period of time. Combined with Valoya’s patented spectra and the support of a team of photobiologists, RX-Series is the way to upgrade to LEDs in your greenhouse.
