Hydroponic Growing Power Point Presentation Mar10 TH

Hydroponic Growing Growing plants without soil Presented by:

Tim Hauber Grower Lucayan Tropical Produce

 What does Hydroponic mean? 

Hydro = water



Ponic = labour

Hydroponic vs. Soil

 The food is in the water.  Vs

 The food comes from the soil

 Advantages of Hydroponic Hydroponic    

 

No soil is needed Lower water costs Control the nutrition levels No nutrition pollution is released into the environment Potential for stable and high yields Pests and diseases are easier to get rid of than in soil

Nutrients needed for Plant Life 

NPK and minor elements



Nitrogen Phosphorous



Potassium



 

Sulphur, Calcium, Magnesium Copper, Molybdate, Boron, Zinc, Manganese

Other needs for plant growth 

 Air (Oxygen / Carbon Carbon Dioxide) 



Light

 Water

ROOTS 

Nutrient absorption takes place in roots 



Roots need dissolved OXYGEN 



Root health is very important

Stagnant water cannot hold Oxygen

 The more root mass mass the more nutrients can be absorbed and the more growth is possible

ROOTS

 To be a successful hydroponic hydroponic grower you must create an environment for good root growth 

Media 





Some type of media is necessary to create the ideal environment for the roots No nutrients are obtained from the media Different types of media have different ‘physical’ attributes

 Types of Media Expanded clay   Rockwool  Coco peat (Coir)  Perlite and Vermiculite  Sand and gravel   Wood chips  Rice hulls  Packing peanuts… 

 Types of Hydroponic Hydroponic Systems 



Static solution culture

Continuous flow culture 

 Aeroponics

Static Solution Culture

Continuous flow culture

 Aeroponics

Hydroponic and Greenhouses Hydroponic growing can be done indoors, outdoors or in Protected Agriculture  Example of Protected Agriculture is a Greenhouse Protected Agriculture   Advantages of Protected 

Better control of environmenta environmentall conditions  Protection from invasive insects and diseases  Extended season for growing   Increased yields, higher plant density   Less land needed 
