Growing food without soil is not a new science but a new trend among agripreneures. There are many benefits behind this soil-less farming which is attracting farmers to give a try. Even many organizations are taking this approach to solve the hunger problem around the globe and beyond, yes NASA is testing hydroponics to start farming on other planets. Let’s explore some salient features of hydroponic farming.
Save Fuel - No tractors, harvesters’, etc.
Free of chemicals - No pesticides.
Nutrients - Complete control over nutrient balance
No Yard Needed - Create a hydroponic garden in any indoor space.
Water-Saving - Hydroponic gardens use up to 2/3 less water.
Affordable - Get started on a very low budget, and save on any size of project.
Higher Yields - Hydroponic gardens are far more productive for their size
Better Results - Hydroponics produces better tasting, more nutritional results.
Year Round Growing - With hydroponics, you control the season.
Enjoyment - Your success is all but assured with hydroponics.
Relaxing - All gardeners tell you the same thing, it is a relaxing hobby.
Types of Hydroponic Systems
1. The Aeroponics System:Plant roots hang suspended in the air and are periodically misted with the nutrient solution.

2. The Deep Water Culture System:Plants are supported on a floating material while their roots hang below in the nutrient solution.

3. The Drip System:Emitters drip the nutrient rich water solution onto a growing medium where the plant roots are located. Emitters drip water down the vertical grow tower less than 5 gallons of water daily to grow up to 5,000 plants. A wicking material helps draw the water to the roots growing throughout the tower. The water that isn’t consumed by the plant flows out the bottom of the tower and is then recirculated right back to the emitters. Water efficiency at its finest!

4. The Ebb and Flow System:Plants grow in a bed that periodically floods and drains with the nutrient rich water solution. A shallow trough, holding up to 12 trays of seedlings, is pumped full of water and then allowed to drain several times each day. This timing provides just the right amount of water for the seedlings to grow.

5. The N.F.T. System: The nutrient solution is pumped through a channel in which the plant roots lie.
