Hydroponics, the name given to techniques used to cultivate plants without soil, is a very important technique used to produce high value crops such as vegetables in areas where soils are normally not suitable for crop production. The plants can be grown in an artificial substrate of some sort to provide support, or with their roots suspended in the nutrient solution, which is nothing more than water containing dissolved fertilizer to provide the plants with all the nutrients necessary for growth.

The following courses can be presented:

  • Hydroponic systems

This course covers the main types of hydroponic systems that can be used, their advantages and disadvantages, and their suitability for various crops.

  • Substrates for hydroponics

Here you will learn about the various media that can be used in hydroponic systems to replace soil in order to provide support to the crop. The advantages and disadvantages of each is covered.

  • Crop nutrition in hydroponic systems

When grown in soil the crop obtains all of its nutrients from the soil, and minor problems in fertilisation will not cause major issues in production as the soil also contains sufficient nutrients to make up any minor shortfall in fertilisation. In hydroponics, however, the plant is totally reliant on the nutrients provided in the nutrient solution, and issues here can result in total crop failure. This course show how nutrient solutions are made up, and also provides information on evaluation of water quality for use with ready mixed nutrient powders. Adjusting nutrients to suit the quality of water being used is also covered.

  • Courses on specific crops in hydroponic production

The specific production practices that are used to produce the most common vegetable crops in hydroponic systems are covered in these courses.

  • How to conduct a feasibility study for a hydroponic operation

This particular course equips the prospective producer with the necessary knowledge to be able to evaluate the economic feasibility of a hydroponic operation. I cover the information required, as well as how this information is used to determine if it is feasible to begin with hydroponic production.

  • Home Hydroponics

This is a course specifically designed for city dwellers who want to grow their own vegetables, flowers and herbs on patios or balconies. It covers all of the essentials for small-scale hydroponics, and even includes information on how to build your own hydroponics system.
