"Trees do not need more water. Trees need stable moisture."
— A Ca, BrainFarm
Mach Thuy Hoan is one of 18 independent experimental projects in the IP Experiment ecosystem created by Vu Truong Ca (A Ca).
Each project documents real-world experiments across health, agriculture, and ecological living systems.
The goal of this ecosystem is to build a long-term knowledge archive based on real-world data rather than theoretical models.

The Mach Thuy Hoan system follows four ecological principles:
Key Philosophy:
"Trees do not need more water.
— A Ca, BrainFarm
Trees need stable moisture."
Underground reservoir = 1,500 m³ × Area (ha)
Hill-top reservoir = 150 m³ × Area (ha)
Forest channels = 10 lines × Area (ha)
Investment cost = 250 million VND × Area (ha)
Drought days = Reservoir volume ÷ 6 m³/day
This system is currently based on field experiments in Central Highlands conditions.
Results may vary depending on:
Further validation in different regions is required.
I am Vu Truong Ca. Since 2006, I developed farms in Long An (0.72 ha), Dong Nai (0.13 ha), and Lam Dong (0.39 ha), including a 76.8 ha project in Da Teh, Lam Dong as Chairman of Kim Minh Investment Corporation.
During the El Niño drought of 2014–2016, I suffered devastating losses:
| Crop | Loss |
|---|---|
| Gac fruit | 2.7 ha completely lost |
| Fruit trees | 0.6/1.2 ha severely damaged |
| Rubber trees | ~3/15 ha depleted |
I learned a hard truth: "Having water is not the same as controlling water."
From these losses, Mach Thuy Hoan was born – to help farmers achieve water autonomy and sustainable harvests.
