1. Regional Context & Agricultural Challenge

Smallholder farmers and student agri-entrepreneurs around Mymensingh needed a way to maximize production on tiny 200–400 sq ft homestead plots and urban rooftops.

2. Technical Implementation & BARI Protocol Applied

Following BARI Chapter 7 Vertical Hydroponics engineering, growers fabricated A-frame iron stands holding three tiers of 6-inch uPVC pipes (2.5m length each). A small submersible pump feeds nutrient solution to the top pipe, cascading by gravity through the middle and lower tiers back into the sump tank.

3. Harvest Results, Economic Impact & Grower Outcome

Each vertical frame holds 72–90 plants in the footprint of just 24 horizontal plants, cutting land and water requirements by over 70%.
