Stadium Grass Grow Lighting


Improve your natural grass pitch by using smart technology. RSI is the exclusive distributor of Rhenac GreenTec LED assimilation technology. The color rendering produced by these LED lighting rigs stimulate germination, the development of premature grass blades and pitch regeneration. Proper grass growth conditions are usually hindered by non-conducive venue design.

About RSI-Rhenac

Rhenac GreenTec was the first company to recognize the significance of supplementing a balanced combination of color to grass pitches. In conjunction with scientists from the Technical University of Munich, Rhenac GreenTec established the exact dose blue or red parts of the visible spectrum. This is the type of light grasses need for photosynthesis.

They were also the first to succeed in packaging this knowledge in LED-powered lighting rigs. The highly accurate LED technology used allows the rigs to deliver this dose with pinpoint accuracy onto the sections of the field where it is needed. The Rhenac GreenTec LED technology consumes less energy and produces less heat compared to conventional sodium vapor luminaires used in out dated technology. That is why they not only deliver but also maintain their commitment to ensuring a good quality natural grass pitch.

RSI offers three different units:

  • The R-ML30 is perfectly suited for goal mouth and problem areas
  • The R-ML200 is a mobile unit that can cover an entire pitch
  • The R-BL is a fully automated system with data-gathering equipment and sprinklers adding additional value

Its knowledge about light and light quantity has enabled Rhenac GreenTec to develop a sustainable and environmentally-friendly treatment for algae, fungus and diseases commonly experienced in natural grass fields.

The Rhenac GreenTec UV-C produces a specifically defined color green that frustrates the growth of fungus and algae on any surface. The light can also treat plant diseases.

The UV-C unit folds out to a width of 6m. It fits on any tractor commonly used by grounds maintenance crews. Thanks to special foam makers, a full-size football field can be treated within 30 to 45 minutes. We can offer an adjusted version that can be used for golf courses or other areas where slopes occur. Documented data show a 95% reduction of fungus and algae when a field is treated two or three times a week.

The Rhenac GreenTec UV-C has proven to be effective on both natural and synthetic surfaces. Adopting this method allows clubs and venue owners to save on pesticides or the need for special permits.

Influence of light explained

All vegetation is sensitive to shade. Plants require light and CO2 for photosynthesis. Stimulating or adjusting the Daily Light Integral (DLI) could help to reduce the rooting time of cuttings and seedlings, and increase crop quality at reduced levels of energy.

Light is the driving force for photosynthesis, the process that changes sunlight into chemical energy within plants and grasses. During photosynthesis, water is split in a chemical reaction and separated into oxygen and hydrogen. In this process carbon dioxide (CO2) is converted into sugar.

A general rule of thumb is that 1% more light will produce a similar percentage increase in growth, resulting in a 1% higher yield.
