30% energy savings with Climalux grow lamp

In a trial of full-led grow lights from Climalux, conducted by HortiTech at research center PROOF with the tomato variety Martice on rockwool, it was shown that the Climalux grow light system resulted in savings of over 30% compared to the reference department with the same electricity consumption, light intensity and similar light spectrum.

In addition to energy savings, higher water and nutrient uptake was observed, which affected plant growth. Plants in the Climalux section were found to be stronger, fuller and more vigorous than in the reference.

For comparison, LED lamps with identical color spectrum and electric power were hung in the reference ward. Both departments were equipped with the same technology. With the climate settings, watering and planting operations, an identical crop was aimed for in both departments. Planting measurements started in week 46 and were conducted weekly. Leaf samples were also taken for understanding nutrient uptake.

All of Climalux’s grow lights are composed of a dimmable lighting unit and a vertical ventilation system, which distributes heat and moisture evenly throughout the greenhouse. This system not only effectively cools the LEDs, but also moves the air about four times per hour.

The latest news from Climalux

More active crop with less energy

More evaporation, more water and nutrient uptake and less energy

When growing a crop in the greenhouse, it is very important that the greenhouse climate is set properly, but also can be controlled in such a way that the crop can grow optimally to achieve good yields. One of the most important elements in the greenhouse climate is the relative humidity. If this is too high then disease pressure on the crop increases and it takes more energy to achieve the right greenhouse temperature, too low and the crop experiences more stress resulting in suboptimal yields.

Grow4you’s experiences

At Grow4You, located in Westland, we focus on the cultivation of various tropical plants, such as Coleus, Episcia, Hoya, Monstera, Philodendron, Scindapsus and Tradescantia, in various pot sizes and product forms. Our experience with the full-LED growth system from Climalux is very positive, and we experience a wonderful Italian spring climate in the nursery in the middle of the Dutch winter.
