Online Hydroponics III Course

There are eight lessons in this course as follows:

1. Options for Managing Plant Culture - different approaches to cultural operations in hydroponics. Organics vs. hydroponics:Nutrient differences in food products. Is hydroponic food more or less healthy than organic? How feasible is organic hydroponics?

2. Planning a Hydroponic Operation - site and crop selection; matching a system with a crop, materials, resources & services required.

3. System Design Components - pumps, hardware, media, pipes, size, type, and so forth. Components for different types of culture.

4. Managing a Hydroponic System in Hot, Humid Conditions - tropical and subtropical climates or summer in temperate areas.

5. Water Management - water quality measures, treatments, runoff,testing, purifying water, water in recirculating and run-to-waste systems.

6. Nutrient Formulation - standard formulations, detecting toxicities & deficiencies.

7. Controlling Nutrient Levels - using EC and pH measures of concentration levels, solution temperatures, and maintaining nutrient levels.

8.Pest & Disease Control - nutrient and pH manipulation for control of pests & diseases, integrated pest management, common pests and diseases.

Aims:

• Describe different approaches to cultural operations
• Demonstrate an awareness of similarities and differences between organic and hydroponic production techniques
• Descrobe how to plan a hydroponic operation through site and crop selection, matching a specific crop, materials, resources and services required, and site layout; for different specific crops.
• Discuss system design components such as pumps, grow beds, solution tanks, media and pipes in terms of size, type, and options for different cultures and specific crops.
• Provide details of how to manage a hydroponic system in hot, humid conditions such as in tropical or subtropical areas, or in summer, in temperate areas, for specific crops.
• Explain options for water management such as water sources, quality, testing, treatments, and use in recirculating and non recirculating systems.
• Recommend awareness of natural and other methods of pest and disease control such as biological controls, as part of IPM and nutrient and pH manipulation for different pests and diseases.
• Explain and recommend different standards of nutrient formulation, and advanced methods of detecting toxicities and deficiencies in specific crops.
• Recommend methods to control nutrient level concentrations by taking EC, pH and temperature measurements, and maintaining nutrient levels for different specific crops.
