General Hydroponics is a leading innovator in the field of hydroponics with factories in North America and Europe. Their products are used by NASA in preparation for hydroponics on the International Space Station. Numerous laboratories and universities throughout the world use their products for teaching and research; BetterGrow Hydro customers use their products for commercial crop production as well as high-tech gardening. When we opened our first indoor and hydroponic gardening shop back in 1992 there were only two lines of nutrients on the shelf - Grow More dry nutrients and the General Hydroponics Flora Series. Wow, that was a long time ago - look how far we've all come since then! Today, General Hydroponics manufactures and distributes so many products we don't even know where to start! The list is too long to display here but here are some highlights: WaterFarm and Power Grower systems (yes, GH pretty much invented the bucket system), AeroFlo, EuroGrower and RainForest hydroponic growing systems, Rapid Rooter and CocoTek growing mediums, pH and TDS calibration solutions, Flora Duo, Flora Nova and (of course) the original Flora Grow, Micro and Bloom series, Diamond Nectar, Flora Kleen flushing agent, FloraBlend, Floralicious Grow, Bloom and Plus, KoolBloom Liquid and Dry flowering enhancers, Azamax for spider mites and other pests and Rapid Start rooting enhancer, just to name a few!
