We have been teaching and collecting information on hydroponics since the early 1970's.
Our principal John Mason, is author of one of the world's best selling hydroponic books (Commercial Hydroponics has sold over 50,000 copies and is in it's 3rd edition since 1990).

Our tutor, Dr Lyn Morgan, is an internationally renowned expert on hydroponics, and a consultant who has worked across the world on commercial installations.

Hydroponics is the art of growing plants without soil. It is the perfect way to avoid heavy, back breaking work, such as digging. Pests, diseases and weeds are generally much easier to control. Over the past few decades hydroponics has proven an ideal method for both keen amateur gardeners and commercial growers looking for an alternative way of producing plants.

With our Hydroponics I course, you will learn:

  • How to grow using hydroponics.
  • How to set up hydroponic systems.
  • Nutrient use in hydroponic systems.

This is the starting point for anyone serious hydroponic grower who is relatively new to the discipline. This course provides an opportunity to interact with and learn from some of the most experienced hydroponic experts available. Our principal John Mason, is author of Commercial Hydroponics (now in its 8th printing) and tutors include Dr Lyn Morgan, author and commercial hydroponic consultant.

Hydroponic Production is in many respects far more environmentally friendly, and sustainable than many other ways of growing horticultural crops. It usually involves using closed systems (so waste products cannot escape, uncontrolled, into the environment); and even though it can be relatively costly to set up, it can produce a lot more per square metre than growing in soil (hence it doesn't have such a large footprint on the environment).

  • Hydroponic production can adapt to climate change if need be.
  • Hydroponic production is less likely to contribute to climate change than some other forms of horticulture.

If you are serious about hydroponics; whether as a business, or a step toward self sufficiency; this course can be an excellent starting point.
