About Us

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.

Our Santa Rosa, Calif., factory features large on-site grow facilities that use alternative energy sources and green technologies to save water and power.

We offer advanced systems powered by solar energy, as well as filtration products that make the most of organic components and nutrient formulations. With manufacturing and research, we continually develop products that enhance your results.

General Hydroponics GH1211 MaxiGro Plant Food for Vigorous Growth

Comprising two powdered, mineral-based options that support your plants from beginning to bloom, the Maxi Series is our most cost-effective choice when it comes to nutrients. MaxiGro encourages growth of seedlings and cuttings, giving your plant starts vital nutrition for that crucial vegetative growth stage early in development.

Good But…
So, the plants seem to like this stuff. It has a lot of micronutrients, although not as complete ie not as many micro nutes as DynaGro. My main issue is, even mixing at the low end of their recommended concentration (5g Maxi/4 Liter H2O) I can never seem to get the product to completely dissolve. They suggest going as strong as 10g / 4 Liter but I wouldn’t dare try because I can’t even get my half portion to dissolve, even after shaking the sprayer full of 16+ lbs of water for 5 minutes.
