General Hydroponics

The leading innovator in the field of hydroponics for more than 35 years.

We share your passion for plants — that's how we got our start, and that's what keeps driving us forward.

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 facility in Sebastopol, Calif., covers 10 acres and provides an ideal environment for testing new crops, hydroponic systems, nutrients, additives and related technologies. Our Santa Rosa, Calif., factory features large on-site greenhouses 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.

It appears in many important plant tissues, such as in seeds and in cellular moisture. In the form of sulphate, sulphur fulfils an important role in the water equilibrium in the plant, as well as in the soil. For hydroponic gardening, all the nutrients a plant needs are given while watering. As a result of this, fertilisers designed for hydro culture contain high concentrations of lime and sulphur. In order to prevent calcium and sulphur from reac ...
