The vertical cultivation of vegetables or certain types of herbs or fruits is becoming popular in cities due to the high yield they produce per square meter, the quality of the crops, the safety that consumers demand and the nutritional value of these crops due to that they do not get lost on the way from the country to the city as we are traditionally used to.
By growing in cities and maximizing the growing space, large harvests can be obtained by shortening the days of production due to the controlled environment, the type of cultivation, usually hydroponic, and the type of artificial light, which is usually LED .
Thanks to LED technology, it has been possible to increase PAR performance and reduce energy consumption compared to traditional fluorescent tubes since what was done in the past with a 58W fluorescent tube can now be done with a 32W tube, drastically reducing the energy consumption and substantially increasing the PPFD.
Also thanks to LED technology, it has been possible to incorporate chips with UV, FR or IR to increase efficiencies or modify phytochromes, shortening the days of production and improving organoleptically to the culture, providing a greater amount of secondary metabolites such as anthocyanins or terpenes.
Also thanks to LED technology, this type of product (tubes) has been able to extend their useful life from 20,000h of old fluorescent tubes to 50,000-85,000h of current LED tubes, as well as reducing the danger of explosion and contamination of crops if there is some human accident or overload of the feeding system. LEDs do not explode and do not contain mercury or other hazardous chemicals for humans or crops, so we can say that it is a safe and efficient technology.
