Hawthorne Gardening Company is a complete growing solutions provider built to serve the growers of today and tomorrow with high-impact solutions for high-value growing. We bring together proven brands, commitment beyond product and bold R&D investments to help you exceed your growing ambitions.

The brands that matter. Through our signature brands we've blazed trails since 1976, across lighting, nutrients, growing media, fans and more. Our rich pro horticulture growing expertise and resources enable us to deliver industry-leading investments in Research and Development, breakthroughs in quality assurance, best-in-class formulation development, tailor-made commercial services and more.

Bold investments for a bright future. We’re dedicated to delivering products and services that help you unearth extraordinary growing potential. That’s why we’ve invested in cutting-edge R&D facilities across the United States and Canada, including locations in Marysville, OH, Vancouver, WA, and Santa Rosa, CA. At our Ohio headquarters, several acres of outdoor space and 12 greenhouses capable of diverse growing conditions enable us to research everything from fruits to trees, veggies to ornamentals, and beyond.

With our new Kelowna, British Columbia R&D facility, we’re adding even more crops to that list. At 50,000 square feet, this location is set to be the world’s first—and largest—purpose-built research and development facility dedicated to cannabis cultivation. Together, all of our state-of-the-art laboratories, indoor and greenhouse grow suites, and specially designed training and breeding areas allow us to tailor, test and fine-tune products and services better than anyone else.

Backed by the best. Thanks to unmatched investments in research and development, we’re able to deliver breakthroughs in quality assurance, custom formulation development, commercial services, and more.
