What is GutterGrow?
GutterGrow is a modular vertical growing system developed by Virtual Workgroups as part of our sustainable horticulture programme. The system uses standard guttering arranged vertically, with a cascading nutrient irrigation design and a perlite growing medium.
The latest revision features a perlite channel and cascading nutrient irrigation, controlled by a low-power microprocessor running MicroPython. The system can be monitored and controlled remotely via Wi-Fi or Bluetooth from any device.
Key Features
- Vertical design — maximises growing area in small spaces
- Perlite growing medium — excellent drainage and root aeration
- Cascading irrigation — nutrient solution flows by gravity through channels
- MicroPython software control — runs on ESP32 or Raspberry Pi Pico
- Wi-Fi & Bluetooth — remote monitoring and alerts on any device
- Solar-compatible — designed for 12V low-power operation
- Open source — DIY-friendly with full guides available
