We’re not just growers. We’re the Original Growers.

At General Hydroponics, growing is at the heart of who we are and everything we do. We live it and breathe it. We’re not just helping along an entire movement of like-minded difference makers, rule breakers, and boundary pushers — we’re leading it.

As industry pioneers with more than 45 years in the game, you could say we’re one of the OGs of hydroponics. We’ve come a long way from our humble origins as a scrappy garage-based startup to becoming the leading name in high-impact growing solutions on a global scale. But the philosophy, development, and innovative spirit at the heart of our products is anything but old school.

We believe in the underdogs. The rebels. The nonconformists. Because that’s exactly how we got our start.
