Our Story

A leading innovator in the field of hydroponics with factories in North America and Europe

General Hydroponics was founded over 35 years ago, by Lawrence Brooke. Lawrence’s inspiration for his first hydroponic system was a mountain stream and the plants thriving beside it. This system was prototyped and General Hydroponics began.


Lawrence forged relationships with renowned botanists and chemists while attending UC Berkeley in the 1970’s and it was in those early years of his research that General Hydroponics’ legendary pH stability was developed. Dedicated to GH since the beginning, Cal Hermann was one of Lawrence’s colleagues then, and is still the Head Chemist for the company now. And the UC system where it all began continues to test our formulas in their state-of-the-art research centers at UC Davis and Berkeley.

Situated in the heart of Sonoma County, California, General Hydroponics sits on ten beautiful, sun drenched acres. The warehouse and production factory at General Hydroponics is 45,000 square feet of state of the art industrial space with a roof top covered in a multi-million dollar solar array. The massive greenhouses are filled with plants for testing systems and nutrients- basil, lettuce, peppers, tomatoes, sunflowers and more. Impressive ornamentals are grown as well. Behind the greenhouses, GH also farms in the lush soil, growing everything from giant pumpkins to 1/4 acre of delicious strawberries.


General Hydroponics is proud of its tradition of bringing nature and technology together. GH will always continue to strive for quality, simplicity, innovation, and a sustainable future.
