2000 Scientific experiments with DuPont Corporation in germination and grow out properties of a commercial fiber designed for hydroponic culture


2001-2003 Established the International Institute of Simplified Hydroponics Training Center in Tehuacan, Puebla Mexico. A 256 square foot building was revitalized and 3000 m2 demonstration gardens established in the city. Funds of over $100,000 were raised for the project, educational tools were translated and printed into Spanish. Classes for students started from Mexico and Latin America.
