ntroduction to Hydroponics Gardening

Learn how to grow plants without soil and plan your own hydroponic garden. This introductory course explains how water, nutrients, light and oxygen work together to support healthy plant growth.

Designed for learners in Australia and worldwide, the course explores common hydroponic systems, suitable crops, equipment, nutrient products and everyday maintenance. Practical examples help you understand pH and electrical conductivity (EC), recognise growing problems and make decisions suited to your local climate, water source and available space.

What you will learn

• Explain the principles of hydroponics and the needs of plant roots.
• Compare wick, Kratky-style, deep water culture, NFT, flood-and-drain, drip and aeroponic systems.
• Choose suitable crops, containers, growing media and a safe location.
• Understand water quality, root oxygen and temperature.
• Read nutrient-product directions and perform basic calculations.
• Interpret pH and EC readings and maintain monitoring equipment.
• Start seeds, transplant seedlings and care for growing plants.
• Investigate common problems using observations and records.
• Apply hygiene, chemical-handling and harvest-safety practices.
• Evaluate water use, energy consumption and responsible disposal.
