More and more greenhouses are being equipped with LED lighting, both for horticulture and floriculture. HPS lighting, which generates radiant heat that most LED lighting lacks, is about 45% less efficient. In any case, there are several factors that need to be taken into account to get the most out of LED cultivation.

First, make a proper selection of the type of LED lighting depending on the type of crop. For many, specific light recipes have been developed and more than 150 can already be selected.

Secondly, we must take care of the circumstances so that the plant distributes the assimilates created by photosynthesis in the parts of the plant where we want them to go, which are usually the fruits or flowers. To maintain this activity, the key is the drainage of the liquid around the plant. The installation of fans, minimal heating tubes or active dehumidification can be considered. In any of the options, the energy saved thanks to LED should be slightly compensated by a higher heat input.On the other hand, for optimal growth, the plant should always be the center, so water absorption and development speed, among other things, should be observed to adjust the climate and keep the crop balanced. When growing with LEDs, the temperature of the plant must be controlled more than that of the environment.

Fourthly, this temperature control of the plant must be done through shielding. It has also been proven that using an energy screen in addition to shade screens is a great advantage.

Finally, artificial lighting will make the light sums stable, and therefore the available light sum must be used to create a stable crop to ensure continuity. For this, a plant density, crop weight, harvesting stage and pruning strategy must be taken into account.
