General Hydroponics was founded in 1976 by Lawrence Brooke in Berkeley, California. Over nearly four decades GH has transformed itself from a garage based start-up to a modern state-of-the-art manufacturing and development facility in the heart of Sonoma county.

Over 40 years ago, an inspired group of scientists, engineers and technicians came together with an ambitious goal: to advance agricultural quality and innovation through the use of key manufacturing processes and cutting-edge research.

They succeeded. But it was only the beginning.

In launching General Hydroponics, that team created a foundation that’s allowed us to expand in meaningful and industry-changing directions. We now have state-of-the-art facilities in North America and Europe where researchers develop products, solutions and systems that help you care for your plants in a way that delivers the best possible results.

Our Santa Rosa, Calif., factory features large on-site grow facilities that use alternative energy sources and green technologies to save water and power. A specialized farm division has tested over 100 plant varieties for yield, flavor, nutrition, appearance, disease resistance, growth rate and suitability for hydroponic systems.

While improving our customers’ growing practices, we’re also dedicated to creating a cleaner and more environmentally efficient world. That’s why we offer advanced systems powered by solar energy, as well as filtration products that make the most of organic components and nutrient formulations. With industry-leading manufacturing and research, we continually develop products that enhance your results while being kind to the environment.

We honor the vision of our founders by always thinking about what’s next. With consistent quality, value and results, General Hydroponics remains committed to leading the industry, offering the most innovative products available and serving growers like you around the world.
