Duration (approx) 100 hours
Qualification Statement of Attainment

A Foundation course in Hydroponic Supply and Consultancy

Learn about hydroponic suppliesDevelop a foundation of skills and knowledge, enabling you to confidently advise customers buying hydroponic supplies; and provide support through developing guidelines for the successful culture of plants.

A Course For:

  • 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.

This course does overlap significantly with Hydroponics I and with Home Hydroponics, and you should avoid doing more than one of those three. The difference is that Home hydroponics is a less intensive academic load, and geared to the hobbyist, while hydroponics I is a broad based course.  This course is written specifically for people who are in a position of supplying services or products to hydroponic growers, both amateur and trade.

Courses can be started anytime from anywhere in the world!

Learn and Earn with an Expert Knowledge of Hydroponics

Learn about hydroponic suppliesHydroponics 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.

Throughout the 90's she worked in both the nursery industry and horticultural crop production, before establishing her own business "Suntec" which has built an exceptional international reputation providing consulting services; particularly in hydroponic crop production. Dr Morgan has a broad expertise in horticulture and crop production, and a keen appreciation of the global scene. She travels widely as a partner in Suntec Horticultural Consultants, and has clients in central America, the USA, Caribbean, South East Asia, the Middle East, Australia and New Zealand.

Check out our eBooks

Marketing PsychologyThe Marketing Psychology ebook will provide you with an understanding of the psychology behind the consumer decision making process. With 52 pages of insight into marketing psychology and consumer behaviour, this ebook help you understand consumers much more effectively. Marketing psychology is about understanding people’s purchasing behaviour and applying that understanding to the advertising, marketing and ultimately the selling of products or services.
Capsicums and ChillisCultivars, growing at home or commercially, how to use them, recipes for different cultures, lots of photos.
Aquaponics eBookThe Aquaponics ebook will give you a great understanding of how to start your own aquaponics production. This 65 page ebook provides you with enough information to start your own home production and even manage issues as they arise. This is a great way to become more self-sufficient and produce a sustainable food source for your own household. Aquaponic farming allows individual families to grow a much wider range of produce, in a much smaller space. They can provide the protein needed for their diet (from fish), as well as the vegetables and fruit they need. Aquaponic systems can be as small as a few cubic meters; or as large as many acres. They are an ideal way of improving productivity on a hobby farm; can be used by restaurants to produce the freshest produce on site, or established inside buildings, in big cities, for urban farming.
Commercial HydroponicsThe Commercial Hydroponics ebook is ideal for students, professional horticulturalists and those who want to build a strong foundation knowledge in hydroponics. The commercial hydroponics ebook explains how to set up a commercial hydroponics system, including growing techniques and equipment that you will need. The topics covered in this book include an introduction to hydroponics, site considerations, alternatives, plant nutrition, nutrient film technique culture, rockwool culture, aggregate culture, other techniques, hydroponics equipment, greenhouse operation, plant culture in hydroponics, Vegetable crops, berry and other fruit crops, flower crops, other crops, managing a commercial hydroponic farm and a troubleshooting guide.
