In 2022, farmer Cao Văn Hùng from Đông Triều, Quảng Ninh, Vietnam, invested over 1 billion VND (approx. $40,000) in the first hydroponic gotu kola (Centella asiatica) farm in the region. Despite a devastating typhoon in 2024 that wiped out his entire setup, Hùng rebuilt his farm, proving that hydroponic gotu kola is not only viable but also a promising model for sustainable, high-tech agriculture.
Why Hydroponic Gotu Kola?
Gotu kola, a nutrient-rich herb traditionally grown in soil, is gaining global demand for its medicinal and cosmetic benefits. Hydroponic cultivation offers higher yields (up to 30% more than soil farming), year-round production, and reduced pesticide use (FAO, 2023). Hùng’s farm now produces 40-50kg of fresh gotu kola daily and 150-200 liters of juice, meeting growing consumer demand for clean, traceable products.
Technology & Sustainability
Hùng’s farm uses:
-
Solar-powered automated irrigation
-
Closed-loop nutrient systems (reducing water use by 90% compared to traditional farming)
-
Coconut coir substrate, enhancing root aeration and disease resistance
Studies show hydroponic systems can cut land use by 70% and increase crop cycles by 3x annually (Journal of Agricultural Engineering, 2024).
Overcoming Challenges
After Typhoon No. 3 (2024) destroyed his farm, Hùng redesigned his setup with reinforced greenhouses and modular hydroponic trays—key lessons for climate-resilient farming. His story mirrors global trends where 65% of agri-startups now prioritize disaster-proof designs (World Bank, 2024).
Market Potential & Future Goals
Hùng plans to expand into value-added products (freeze-dried powder, organic cosmetics) and supply seedlings to local farmers. With the global herbal supplement market projected to reach $86 billion by 2030 (Grand View Research, 2024), hydroponic gotu kola could become a lucrative niche.
Cao Văn Hùng’s journey underscores the potential of hydroponics in transforming traditional farming. By integrating automation, renewable energy, and resilient design, small-scale farmers can achieve higher productivity, sustainability, and profitability. His model is a blueprint for the future of agriculture—where innovation turns challenges into opportunities.
