Automated Hydroponic System Build (2020) (kylegabriel.com)

Article summary

The article describes the construction and automation of a hydroponic system using a Raspberry Pi single-board computer and Mycodo software. The system is designed to monitor and regulate water and air conditions, as well as control pumps and relays to optimize plant growth. The author also discusses the benefits and challenges of hydroponic farming, including water conservation and the need for precise control over nutrient levels. The system is modular and can be scaled up or down depending on the growing space.
