3 reasons why intercanopy lighting is effective for high-wire vegetables
The light spectrum of the LED intercanopy lighting has been optimized to maximize photosynthesis. Red light is the most effective for photosynthesis, so our LED interlighting module has a lot of red light, with a bit of blue to ensure the correct plant development. This module is the result of our research carried out since 2008 which tried out various light spectra for high-wire tomato crops. The spectrum combines light spectra that promote growth and energy efficiency. This light spectrum was installed at Jami in 2012 on a commercial scale, and many growers in other countries have subsequently followed their example. These results prove that our years of research are now paying off for growers.
Leaves are the “growth engine” of a plant. In a high-wire crop such as tomato, leaves are distributed over a height of 2-3 meters. When lit from the top, either by the sun or by artificial lighting, the top leaves receive much more light than the lower leaves. This means that the top leaves are operating at full production capacity, but the lower leaves are not. LED intercanopy grow lights add light at the right place at different levels along the plant, so the leaves in that area become producers instead of being consumers. Since the lights are applied within the canopy, all light is absorbed by the crop. No light is lost due to reflections or to the floor. At Jami there are 2 rows of interlighting to provide sufficient light, distributed evenly over their plants and to fit the low height of their greenhouse.
