General Hydroponics

General Hydroponics Nutrients and Enhancers 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!

  • Rapid Rooter 50/Pack Replacement Plugs

    The breakthrough technology used in RapidRooter results in a unique matrix of composted organic material bound together by plant-derived polymers. RapidRooter is created through a scientifically controlled process which produces large populations of beneficial microbes in the plug media. These naturally occurring beneficial microbes colonize young roots and help young plants to resist disease while maximizing nutrient uptake. The optimal air-to-water ratio within the plug matrix causes explosive early root growth. Use RapidRooter for robust early rooting and explosive plant Growth!

  • pH 7.01 Calibration Solution - 8 ounce

    pH meters should be calibrated frequently (every 1-4 weeks, depending on use). Two-point calibration (using both 4.0 & 7.0 buffers) ensures the most accurate calibration possible. Do not reuse calibration solution, as once it has been used, it is no longer sterile and may result in improper readings. Pour a small amount into a shot glass and discard after use. Suitable for all makes and models of pH pens and meters.

    pH Calibration Solution is available in single-use sachets, as well as 230 ml (approx. 8 ounces.) and quart bottles. We also offer a "twin-pack" containing one 8 ounce bottle each of both 4.01 and 7.01 calibration solution. All pH calibration solutions that we offer are made by either Hanna, Green Air Products or General Hydroponics.

  • FloraDuo A by General Hydroponics

    FloraDuo is a two-part mineral nutrient, FloraDuo A and FloraDuo B. Designed and created in collaboration between Dr. Cal Herrmann and William Texier, this is our new formula, inspired from the latest discoveries in plant nutrition.

    FloraDuo is a "classic" mineral nutrient, with a difference (and an essential one), where each of the elements a plant needs is derived from a large variety of different sources. To create an excellent nutrient, you need of course a precise formula. But this is not all!
