Hydroponics is a good option due to its soil-free cultivation technique, which consists of applying nutrients to water so that the plant develops well, generating harmless products, free of agro-toxins and with greater yield in less time. Hydroponics or hydroponic agriculture (from the Greek ὕδωρ [hýdōr] 'water', and πόνος [ponos] 'labor', 'work'1) is a method used to grow plants using mineral solutions instead of agricultural soil. The roots receive a balanced nutrient solution dissolved in water with the essential chemical elements for the development of plants, which can grow in an aqueous solution only, or in an inert medium, such as washed sand, gravel or perlite, among many others.
