HYDRO - PONICS

CONTENTS Introduction History of Hydroponics Hydroponic system Why grow things Hydroponically ? Working Hydroponics parts Types of Hydroponic System Nutrient Solution System Requirements Advantages and Disadvantages What can you grow ? Conclusion

INTRODUCTION 4 Hydroponics is simply the production of crops without soil . Hydroponics is also an answer to two of the world's growing concerns: diminishing soil quality, and water scarcity. It is technique for growing plants in water. Utilizing this technology, the roots absorb balanced nutrient dissolved in water that meets all the plant developmental requirements. Many aggregates and media support plant growth

HISTORY Hydroponics became popularized by the news media in the 1920s when a scientist named Dr. William F. Gericke of the University of California when he put laboratory experiments in plant nutrition on a commercial scale. So he termed these nutriculture systems HYDROPONICS. The word was derived from the Greek words, HYDRO (water), and PONOS ( labor ), literally “water working”.

WHAT IS HYDROPONIC SYSTEM ? There is no mention of "soil" anywhere in there and that's all the proof you need that plants can grow without it.

WHY TO GROW THINGS HYDROPONICALLY ?

Benefits sometimes questioned….. Some hydroponic growers got many times greater yields than conventional methods. Because hydroponically grown plants dip their roots directly into nutrient-rich solutions, they get what they need much more easily than plants growing in soil. With smaller roots, you can grow more plants in the same area and more yield. Many pests are carried in soil, so doing without it generally gives you a more hygienic growing system with fewer problems of disease.

HOW DOES HYDROPONICS WORK ? Stand your plants in a plastic trough and let a nutrient solution trickle past their roots (with the help of gravity and a pump).

TYPES OF HYDROPONIC SYSTEM

1. WICK SYSTEM The nutrient solution is pumped from the reservoir up the growing tray and delivered to plant roots via the capillary movement of the wick

2. WATER CULTURE Plants are placed in a net pot and are held by a floating platform above a container of nutrient and water. Plant roots are suspended and stretched into the nutrient-rich oxygenated solution

3. EBB & FLOW (DRAIN AND FLOW) Also known as Flood & Drain. The system floods the nutrient solution onto the grow tray to surround plant roots before draining back. Often automated by a pump connected to a timer.

4. DRIP SYSTEM Drip system pumps the nutrient solution through the tube and drops onto plant roots via a network of drip lines. The action is often made automatical by a timer

Nutrient Solutions In Hydroponics, nutrient control is easy A nitrogen-rich Grow Formula A phosphorous and potassium-rich Bloom Formula & The results? Bumper crops of delicious fruits and vegetables every time.

Plants require 17 essential elements to grow and reproduce The first three are Hydrogen, oxygen and carbon Other 14 are: Mac r o - E l e me n t s : Nit r o g en , P h os p ho r ou s , Potassium, Calcium, Magnesium, Sulfur Microelements : Iron, Manganese, Copper, Zinc, Boron , Chlorine, Molybdenum, Nickel

SYSTEM REQUIREMENTS pH Control 5.8 and 6.4, or slightly acidic Electrical Conductivity (EC) 1.2-3.5 Mho Horticultural Lighting Metal Halide (MH), High Pressure Sodium (HPS) lamps. Temperature and Environmental Control 68- 78 degrees F.

A D V AN T A G E S Soil is not required Water remains in the system and can be reused, thus saving water Nutrition levels are controlled, thus reducing nutrition requirements and costs The controlled hydroponic environment ensures that no pollution from the nutrients is released Plants are healthier with high yields The container is movable, thus pests and diseases can be easily controlled Easy harvesting with shorter harvest time Hydroponic plants are better for consumption There is no damage due to pesticide

DISADVANTAGES Cost of initial investment A high level of expertise is required. Daily attention is necessary. Specially formulated, soluble nutrients must always be used.

WHAT CAN WE GROW ?

WE CAN GROW HYDROPONIC GARDEN AT OUR HOME ….

CONCLUSION Progress has been rapid and results obtained in various countries have proved that this technology is thoroughly practical and has very definite advantages over conventional methods of crop production. Th e m a in ad v a n t a g e s o f soi l - le s s cult i v a tion i s the much higher crop yields. People living in crowded city streets, without gardens, can grow fresh vegetables and barren and sterile areas can be made productive at relatively low cost.
