These systems have not substrates for crop development, which is produced directly on the water-bearing systems by various plants as:
In these systems We grow using inert substrates irrigated by drip irrigation, subirrigation, or exudation. The most common substrates are perlite, rockwool, coconut fiber and peat.
Involves growing by systems where the root stay outdoors, in a container that kept it in the dark, where the nutrient solution is applied as an aerosol mist. The use of hydroponic systems is justified in cash crops that require high control of the production process, such as greenhouse cultivation of cucurbits, tomatoes, pepper and strawberry.
Hydroponic systems require to specify a percentage of drainage, especially in hydroponic substrate systems, in order not to salinize the root environment especially for hydroponics saline waters use.
Depending on the use to be given to the drainage system are classified into:
The drain water in these systems is not reused in production under hydroponics. It is normally used to irrigate other low plots under traditional irrigation systems, as they have unused nutrients not usual in hydroponic system.
Installation of PVC or PE irrigation and accessories needed. Depending on the type of hydroponic irrigation could have:
