WHY HYDROPONICS?

What is hydroponics? What are the benefits of hydroponics?

Hydroponics has been practised by a few market gardeners and other growers since the 1940s. Since that time it's advantages have been increasingly acknowledged and it has grown steadily in popularity. The advantages of hydroponics are many; however, the disadvantages should not be overlooked when you are deciding whether or not to set up a hydroponics system.

Advantages

1. You can grow anywhere

Crops can be grown where no suitable soil exists or where the soil is contaminated with disease.

2. Culture is intensive

A lot can be grown in a small space, over a short period of time. It is also possible to grow in multi-levels. Where transportation costs to the market are significant (e.g. in the centre of large cities), hydroponic farms may be viable irrespective of land values. For example, in Japan hydroponic vegetables are grown in supermarkets in the centre of large cities. The savings on transport costs and the benefits of having fresh produce offsets the increased cost of space in these cities.

3. Heavy work is reduced

Labour for tilling the soil, cultivation, fumigation, watering and other traditional practices can be reduced and sometimes eliminated.

4. Water is conserved

A well-designed, properly run hydroponic system uses less water than gardening. This is an important advantage in areas with poor quality or limited water supplies. In particular, hydroponics is seen to have potential benefits in controlling water pollution in developing countries.

5. Pest and disease problems are reduced

The need to fumigate is reduced. Soil-borne plant diseases are more easily eradicated in many nutriculture systems. This is particularly true in 'closed systems' which can be totally flooded with an eradicant. The chance of soil-borne human disease is also reduced. Though rare in developed countries, it is possible for diseases to be transmitted from animal manures or soil micro-organisms onto food plants grown in soil, leading to illness.

6. Weed problems are almost eliminated

Weeds are a major problem in most soil-based systems. Weeds are almost non-existent in hydroponic setups.

7. Yields can be maximised

Maximum yields are possible, making the system economically feasible in high density and expensive land areas.

8. Nutrients are conserved

This can lead to a reduction in pollution of land and streams because valuable chemicals needn't be lost.

9. The environment is more easily controlled

For example, in greenhouse operations the light, temperature, humidity and composition of the atmosphere can be manipulated, while in the root zone the timing and frequency of nutrient feeding and irrigation can be readily controlled.

10. Root zone chemistry is easier to control

Salt toxicities can be leached out; pH can be adjusted; EC (electroconductivity) can be adjusted. Also salts will not bind chemically to the majority of media used in hydroponics so problems of salt build-up that may occur in soils, particularly when highly soluble nutrients are used, are uncommon in hydroponics.

11. New plants are easier to establish

Transplant shock is reduced.

12. Crop rotation/fallowing is not necessary

All areas can be used at all times - you don't need to leave a paddock for a year to fallow every so often.

The amateur horticulturist can use hydroponic systems at home, even in high rise buildings. A nutriculture system can be clean, light weight, and mechanised.

Disadvantages

1. Initial cost is high

The original construction cost per hectare is great. This may limit you to growing crops which either have a fast turnover or give a high return.

2. Skill and knowledge are needed to operate properly

Trained plantsmen must direct the growing operation. Knowledge of how plants grow and the principles of nutrition are important.

3. Diseases and pests can spread quickly through a system

Introduced diseases and nematodes may be quickly spread to all beds using the same nutrient tank in a closed system.

4. Beneficial soil life is normally absent

5. Plants react fast to both good and bad conditions

The plants in hydroponics react more quickly to changes in growing conditions. This means that the hydroponic gardener needs to watch his plants more closely for changes.

6. Available plant varieties are not always ideal

Most available plant varieties have been developed for growth in soil and in the open. Development of varieties which are specifically adapted to more controlled conditions may be slow to occur.

Meet some of our academics

John L. Mason Auithor of "Commercial Hydroponics", one of the world's best selling hydroponic books for more than 20 years. John completed a Diploma in Horticultural Science at Australia's oldest horticulture college in 1971. In 1974 he was asked to create and teach a hydroponic course for Council of Adult Education in Melbourne, Australia. Despite a strong and broad background in horticulture that included crop production, his practical experience with hydroponics was at that point limited. He established hydroponic gardens both at home and in the lecture rooms of CAE in Melbourne; and has been involved with hydroponics on many levels ever since.
Rosemary Davies Rosemary trained in Horticulture at Melbourne Universities Burnley campus; studying all aspects of horticulture -vegetable and fruit production, landscaping, amenity, turf, aboriculture and the horticultural sciences. Initially she worked with the Department of Agriculture in Victoria providing advice to the public. Over the years she has taught horticulture students, worked on radio with ABC radio (clocking up over 24 years as a presenter of garden talkback programs, initially the only woman presenter on gardening in Victoria) and she simultaneously developed a career as a writer. She then studied Education and Training, teaching TAFE apprentices and developing curriculum for TAFE, before taking up an offer as a full time columnist with the Herald and Weekly Times and its magazine department after a number of years as columnist with the Age. She has worked for a number of companies in writing and publications, PR community education and management and has led several tours to Europe. In 1999 Rosemary was BPW Bendigo Business Woman of the Year and is one of the founders and the Patron, of the Friends of the Bendigo Botanic gardens. She has completed her 6th book this year and is working on concepts for several others. Rosemary has a B Ed, BSc Hort, Dip Advertising & Marketing
Dr. Lynette Morgan Lyn has a broad expertise in horticulture and crop production. Her first job was on a mushroom farm, and at university she undertook a major project studying tomatoes. She has studied nursery production and written books on hydroponic production of herbs. Lyn has worked on horticultural projects in countries from the middle east to the Americas and New Zealand to the Phillippines. Lyn has been a tutor with ACS since 2003 and has contributed to the development of a range of hydroponic courses.
Adriana Fraser Adriana has written about gardening and self sufficiency since the 1980's and for many years was a frequent contributor to Grass Roots Magazine. She has lived what she preached; developing large gardens and always growing her own fruit, vegetables and herbs; and making her own preserves. In 1992 she formalised her training by graduating with a certificate in horticulture; and a few years later, completing an Advanced Diploma in Horticulture. Adriana has worked across a broad spectrum of the horticulture industry; and has developed a strong network of contacts in horticulture around Australia and beyond. She has written and contributed to many books and magazine articles; and at one stage managed the national collection of Thyme. She has a passion for plant knowledge and sustainability and an inert understanding of how people learn about horticulture. Adriana has been a tutor with ACS since the mid 90's and based on the feedback from past students has been an overwhelming success in helping people develop their skills and further careers in horticulture.
