Why hydroponic
Hydroponic = Hydro (water) + Ponic (labour)
Advantages of using hydroponics over soil culture
1. Crops can be produced on non-arable land (not fit for farming). Ex. Land with poor soils, and contamination (ie., high heavy metal and salinity levels). The grower doesn't have to have good soil since the systems, bags, etc. are placed on top of the ground.
2. Isolation from diseases or insect pests usually found in the soil. The greenhouse can be a physical barrier to insects and diseases.
3. Direct and immediate control over the rhizosphere.
4. High planting densities are possible which minimizes use of land area.
5. Higher yields are possible, by controlling over the aerial (upper) portions of the plant.
6. Efficient use of water and nutrients.
7. Ease of cleaning the systems.
8. No weeding or cultivation is needed.
9. Transplanting of seedings is easy - No transplant shock.
10. Fruit of hydroponically grown plants can have more flavor.
