Hi,
Sample:
GARDENING: HYDROPONICS
Hydroponics, derived from Greek words “hydro” (meaning water) and “ponos” (meaning labor) is an innovative method for growing plants with the use of mineral nutrient solutions, devoid of soil. It is basically a technology involving the growth of plants in certain nutrient solutions including water based fertilizers that may or may not contain any artificial medium , such as, vermiculite, gravel, rockwool, peatmoss, perlite, sawdust or coir, in order to support the plants mechanically. Hydroponics systems can either be liquid or aggregate; the liquid systems do not have other medium for support while the aggregate systems have a support medium which is solid. Hydroponics has been defined to state only the liquid systems thus confining its usage and underestimating the technology’s scope and implications to the economic conditions.
The hydroponics systems in the world’s temperate regions are well enclosed in typical greenhouse-styled structures so as to enable temperature control, minimize evaporation and diminish pest infestations and diseases in vegetables and plants. It is the most highly prolific, conservative of land and water and the protective shield of the atmosphere.
The Basics
We all know that plant foliage needs oxygen; light as well as carbon dioxide and the root systems of the plant require water, oxygen and essential nutrients.
