Hydroponics is not only used industrially for soilless greenhouse cultivation but also domestically by amateurs for both indoor and outdoor cultivation of ornamental plants, flowers, fruit, vegetables, weed, and gardening in general.
Hydroponic systems for small-scale cultivation in pots or with automated systems use the same technologies as professional hydroponics but on a smaller scale, and are easy to find in the retail market.
These small-scale systems make it possible to create authentic hydroponic vegetable gardens inside a house or on roofs, terraces, and balconies.
Laterlite Agri Expanded Clay (also known as expanded clay grow rocks, expanded clay pellets, or expanded clay pebbles) has a special granulate that provides ideal support for domestic hydrocultivation because it
Various plants are known to be particularly suitable for hydroponic cultivation in expanded clay, including indoor species like Dracena, Ficus, Dieffenbachia, Sanseveri, and different varieties of orchids or weed, chili peppers etc.
Typically, a hydroponic system for indoor plants will use special perforated pots or trays placed within a larger container into which a solution of water and nutrients is fed. This solution is partly absorbed by the Laterlite Agri granules and thus becomes available to the root system.
An indicator (hydrometer) in the pot monitors the water level, which should be in contact with the lower part the root system without completely submerging it.
The expanded clay plays a fundamental role in maintaining the correct balance of water, mineral, and oxygen in the nutrient solution.
Using the same principles, expanded clay is used with success in aquaponics and phytopurification systems, such as constructed wetlands.
