HYDROPONICS GIVES YOU GREATER CONTROL OF CROP PRODUCTION

Hydroponics offers more than anything else, possibilities for plant culture that did not exist before. Hydroponics can make better use of limited water resources, and can reduce or eliminate the need for chemical pest control in a commercial situation. Hydroponic produce can in fact be less tainted by chemical residues than produce from a traditional farm.

 
Hydroponics may offer the possibility of "perfect growing"; but in reality; things can still go wrong no matter what you do in horticulture. The fact always remains that you are dealing with living things and living things are never 100% predictable.
 
For Example:

What can Happen When the Nutrition Goes Wrong?

The nutrient solution in hydroponic systems provides an ideal environment for a number of other forms of life to grow and multiply. Plant life such as algae is common, and microbial populations exist in most healthy nutrient solutions unless some form of sterilisation is used. Nematodes, insects such as mosquito larvae and others, can proliferate in some nutrients and may cause plant growth problems. Nutrient solutions provide the ideal breeding ground for many plant pathogenic fungi and bacteria since they contain mineral elements, usually some organic matter, moisture and are often warmed to just the right temperature for optimum microbial growth. Bacteria, fungi and algae are also very commonly carried in water supplies, on media, seedlings and old root systems, on equipment, transported by humans, animals, wind and in dust, making complete avoidance difficult. Despite this, most well run hydroponic systems don’t often have problems with odour, bacterial growth or insects, but when they do establish, control needs to be swift as certain nutrient problems will rapidly cause root death and plant decline.
 

WHO IS THIS COURSE FOR?

  • Hydroponic farmers and staff
  • Horticulture entrepreneurs
  • Horticultural researchers
  • Passionate  hydroponic amateurs
  • CPD for anyone working in crop production

This course was developed to cover key issues which have been identified as recurrent problems for many experienced growers. It is suitable for anyone who has either completed hydroponics I, or alternatively, has significant prior experience.
