General Hydroponics: Pioneering Soil-Less Growing Since the 1970s

Founded by scientists and engineers in the 1970s, General Hydroponics (GH) is now a global leader—with factories across North America and Europe, and systems used by NASA on the International Space Station.

Why Hydroponics?

• Healthier, faster-maturing plants.
• Less space, less water.
• Automated = survive gardener absence.

GH’s Three Core Techniques

1. Nutrient Film Technique (NFT): Roots suspended in flowing nutrient trough.
2. Aeroponics: Roots misted in air; nutrients via air pump.
3. Aggregate Systems: Roots in inert media (clay pebbles, foam) dipped in solution.

Specialized Nutrition

Soil fertilizers fail in hydroponics. GH’s pH-buffered (5.5–6.5) nutrient formulas (Flora-Series) are lab-tested for yield, flavor, vitamins, minerals. Changed biweekly; only water topped off between changes to prevent root burn.

R&D Leadership

GH’s Farm Division trials varieties for growth rate, yield, nutrition, shelf life, hydro-viability. University and commercial partners worldwide use GH for research and production.

From kitchen counter to space station, GH grows the future of food.
