A HYDROPONICS COURSE THAT WILL TAKE YOU TO THE NEXT LEVEL!

For people who already understand a lot about hydroponics
This course has been developed by industry professionals with decades of experience advising hydroponic businesses and farms.
It was developed to complement Hydroponics I and II; and is intended as training for serious growers and industry professionals.

It takes you through a carefully constructed process of learning; to help you understand the management of a hydroponic system; embed that understanding, raise awareness of the broader industry and help you to connect with sources and resources that are relevant to hydroponics, and will assist you in maintaining a "currency" in your perspective on the industry.
 
Learning to manage hydroponics is more than just gathering factual information: it also requires an ability to choose the right information to apply to the situation at hand; as well as an ability to understand and apply that information appropriately. A book or web site can give you information; but you need to move through a process of learning, and be guided by competent teachers in order to properly learn something: and that is what this course can do for you.

WHAT MATERIALS DO YOU USE WITH WATER CULTURE?

The type of components required in a water culture system will depend on the scale of the operation. For instance, jars may be appropriate in amateur and home hydroponics setups but are unlikely to be required in a commercial scale operation, save perhaps for storing nutrient solutions in. Generally speaking though, a commercial scale water culture venture will have a greater number of components, and in larger sizes.

Water culture systems are the simplest in terms of the types of components required. In a basic system, plants may sit in polystyrene rafts which float on top of tanks containing water enriched with nutrient solution. An alternative is to use a litter tray which sits on the top of the tank. This has a wooden frame and the base is made from plastic with holes for plant roots to pass through. The crown of the plants can be supported with polystyrene pieces.

An air pump is needed to oxygenate the solution and provide air to the plant roots. The pump is connected to an oxygenating stone or perforated pipe. This type of system lends itself well to growing head lettuce.

A recirculating water culture system is slightly more complicated. In this type of system, the nutrient solution is pumped through the beds and is returned through PVC pipes to a main reservoir. As the solution leaves the beds it passes through baffles which also help to aerate it. At least one change of solution is needed per hour for a large 30m bed with 10-12cm of nutrient solution.

In a continuous flow system, nutrient solution is pumped continuously over the plant roots to ensure that the solution reaching the plant roots is perpetually oxygenated.

In some commercial systems, UV sterilising units have been used to kill pathogens such as bacteria, fungi, and viruses in the solution as it is returned to the grow beds from the reservoir tank. However, these units do not combat all pathogens. For instance, pythium is unaffected. They also appear to reduce some of the micronutrients in solutions and, in particular, they precipitate iron into hydrous ferric oxide.

Sensors can also be included to measure levels of electrical conductivity (EC) and pH. The EC can be increased through automatic injections of calcium nitrate triggered by sensor readings. Injections of potassium hydroxide are used to increase the pH reading (raise the alkalinity), and injections of sulphuric, phosphoric, or nitric acids can be used to lower pH readings (make it more acid).

Water chillers can also be installed to reduce water temperatures of solutions during hot conditions. These also oxygenate solutions and circulate them in addition to chilling. Those with stainless steel drive shafts are better in nutrient solutions.
 
 
 

WHY CHOOSE THIS COURSE OVER OTHER HYDROPONIC COURSES?

This course has been developed for either:

  1. To be used as part of a sequence of study (combined with Hydroponics I & II; to provide a college or more advanced academic level of training in hydroponics); or
  2. For someone who already understands the mechanics of hydroponics; or the growing of plants, but needs to learn more about how to connect these two skills together.

Graduates will learn more about how different plants should be managed in a hydroponic system. You may know how to grow vegetables in soil, but translating that knowledge to hydroponics requires a different mindset to working with soil.

Your knowledge of both hydroponics and of plant culture will expand as you proceed through this course, and as that happens, you will begin to see more possibilities for growing crops hydroponically in commercial situations.
