This is an ideal course for those involved with the suppply of equipment and services:
- Hydroponic Shop Managers and Staff.
- Hydroponic Equipment and Materials Manufacturers and Suppliers.
- Others working with hydroponic growers who need a better knowledge of hydroponics; such as irrigation suppliers, greenhouse suppliers, environmental equipment suppliers.
As this course has a significant overlap with Hydroponics I and Home Hydroponics, it is recommended that you only select to study one of these three courses.

Learn and Earn with an Expert Knowledge of Hydroponics
Hydroponics is a big industry, with even bigger potential, offering lots of employment and business opportunities.
There are many things to learn about hydroponics if you are to do it well.
Nutrition management is one of the most complex aspects of hydroponic growing. Nutrients are the building blocks of plant growth. In order to grow plants using hydroponics, some understanding of how plants grow is necessary. Also, to properly make up nutrient solutions or advise others about their use, some understanding of what the different plant nutrients are and what they are used for is required.
Anybody can grow plants in soil with reasonable success, but to grow plants in hydroponics you must understand how the plant grows so that you can control the temperature, water, oxygen and nutrients in the root zone.
Mechanisms of Nutrient Uptake
Plant roots are where nutrient solutions are taken up into the plants. Prior to their absorption into root cells, nutrients reach the surface of roots by three mechanisms - mass flow, diffusion, and root interception.
- Mass flow - the most important of these mechanisms quantity wise is the movement of plant nutrients in flowing nutrient solution.
- Diffusion - is movement by normal dispersion of the nutrient from a higher concentration (such as near its dissolving mineral source) through nutrient solution to areas of lower concentration of that nutrient.
- Root interception - is the extension (growth) of plant roots into new areas where there are untapped supplies of nutrients in the nutrient solution.
All three processes are in constant operation during growth. The importance of each mechanism is in supplying nutrients to the root surface for absorption by the root varies with the chemical properties of each nutrient. Nevertheless, mass flow, because of the large amounts of water flowing to and absorbed by roots as water is transpired from the plant, is the dominant mechanism and supplies about 80% of most nutrients to root surfaces.
Plants also absorb nutrients through small openings in leaves, the stomata. Carbon enters almost entirely through the stomata as carbon dioxide, releasing the oxygen (02) produced during the photosynthesis in gaseous form. Hydrogen, as a part of water molecules, is absorbed through stomata, but this intake is usually small compared to the amount entering through the roots.
More than just the Nutrients though
Understanding nutrition is however just one aspect of what you need to learn. You also need to understand the pumps, irrigation equipment, growing substrates, testing methods and much much more.
Hydroponics is a complex subject; and in some respects, the complexity of the subject creates opportunities for people with appropriate specialised knowledge.
Anyone who has a solid, in depth, technical understanding of hydroponics, will be better placed to work in the industry; whether in a hydroponic shop, farm supply business or as an independant consultant or specialist.
Studying Hydroponics Supply And Consultancy will provide you with a broad understanding and knowledge of hydroponic systems, it components, how to manage environments, media, plant nutrition and much more. Gaining such an understanding will mean you are well placed to offer advice and support in the supply of equipment and resolution of customers problems.
