Abstract

This manual is designed to guide readers in implementing small to medium-scale simplified hydroponic systems for vegetable crop production. Simplified hydroponics takes the principles of commercial high-tech systems and adapts them to use low-cost, locally available materials, making them accessible to smallholders in diverse contexts across the Global South. The manual covers everything from system design and management to adaptation to local conditions. It includes technical instructions for building a simplified hydroponic garden. Since no single solution is universally perfect, each context may uncover the most suitable technology to implement and improve upon, beginning with the systems detailed in this manual.
