1. Greenhouse / Polyhouse Establishment & Regional Agricultural Challenge

At Kodala Tea Estate—one of Bangladesh’s oldest and most prestigious tea plantations in Rangunia, Chattogram—high ambient temperatures and low relative humidity during hot afternoons degraded clonal propagation rooting and tea fermentation microclimates.

2. Drip Irrigation BD Ltd. (DIBL) High-Tech Engineering & Soilless Implementation

Drip Irrigation BD Ltd. (DIBL) engineered an industrial-grade automatic fogging cooling network across the estate facility using high-pressure overhead headers, anti-drip multi-way atomizing foggers, inline filtration, and automated solenoid timing controls.

3. Agronomic Yield, Resource Savings & Commercial Return on Investment

The automated evaporative fogging system cools the ambient air by up to 6.5°C while maintaining a steady 85–90% relative humidity curtain—preserving delicate tea leaf turgor and maximizing clonal nursery survival.
