"Hydroponic Produce Farming"
Soil Free Gardening
Hydroponics is the umbrella under which hydroculture plants are farmed without soil, the nutrient to plants are distributed through water culture. which involves some type of pumping mechanics. The advantages of this action which reduces maintenance for watering and feeding is simply topping up the growing reservoir which includes growing solutions or mineral nutrients. Terrestrial plants are also grown in perlite which is a volcanic glass that has high volumes of water formed from the hydration of obsidian derived from felsic lava, volcanoes that cool fast with a minimum growth forming a crystal. other methods of growing are gravel, mineral wool which are materials of natural fibers and synthetic materials is a lightweight ceramic shell with honeycomb core produced by firing natural clay to temperatures of 1100-1200°C in a rotating kiln and coconut husk.
Researched in the 18th century discovered that plants absorb essential minerals and nutrient as inorganic ions in water, without the need for soil, in a natural environment the soil is the natural mineral nutrient for a plant but is not essential to the plant growth. Soil dissolved in water the mineral nutrient is extracted in the water and the plant roots are able to absorb them. When the water is introduced artificially the extracted minerals and nutrients that are required for the plant the soil is no longer needed for the plant to thrive, and the most terrestrial plant will grow hydroponically.
