Creating a vertical garden out of upcycled materials is a great way to recycle while adding a unique touch to your space. Here's a step-by-step guide for creating a "BioStack" garden:

Materials:
1. Several upcycled plastic containers (try to choose a uniform size for aesthetic consistency). 
2. An old hose or cotton rope for the wick.
3. Landscaping fabric.
4. A large basin or deep tray for water collection at the bottom.

Ebb and Flow, also known as flood and drain, is an effective irrigation technique that's been embraced by gardeners worldwide. Its adaptability, suitability for vertical gardens, and the potential for incorporating upcycled materials make it an attractive option for those seeking a sustainable irrigation solution.
