BOOSTERS the industry standard in boosters Through our research on organic stimulators we have found an extraordinary line of products that we are proud to include in our range. The Terra Aquatica Pro Roots, Pro Bloom and Protect were developed by independent researchers, and our tests, as well as those conducted by several of our clients, were dazzling! Conformed to European regulation CE N° 834/2007 on organic agriculture, manufactured naturally and totally biodegradable. Pro Roots (formerly G.H. Roots) ultra concentrated root booster TA’s concentrated root booster  delivers the results of the original formula in a super concentrated form, allowing mineral growers to minimise the amount of organic matter in their grow. Ideal for systems such as AutoPot that are optimised for mineral nutrition.  Fully organic formulation.

 pH Regulators Premium pH management There is no such thing as an ideal pH. High values help cation uptake and low values help anion uptake: every fixed pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2. GHE pH Up: Premium pH management and silica source for hydroponics, coco and soil. Control pH and boost silica levels at the same time Whilst raising pH level may seem crazy to growers in hard water areas, it’s a real issue with very soft water or when using reverse osmosis. GHE pH Up allows that adjustment, and offers a good source of available silicate - which is often deficient in Hydroponics, due to its very low solubility. Proper silicate levels make a big contribution to plant health and so we include it in products whenever we can.

Liquid pH test kit

Classic liquid pH testing

Fast, reliable, accurate pH testing without batteries

Our liquid pH tester is perfect for easy testing and as a backup to your digital meter. Covering a wide range, from 4.0 to 8.5, our kit gives up to 500 tests with 30 mL.

Simply fill the supplied test tube halfway with nutrient solution, add two drops of pH Test Indicator, shake and compare the resulting colour with the chart to read your pH level.

The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2. GHE pH Down:  Premium pH management and buffering for hydroponics, coco and soil. Not just a simple acid: GHE pH Down makes a real contribution to nutrient solution stability To make GHE pH Down we carefully blend three acids commonly used alone in hydroponics to give you all the benefits of each - without the disadvantages. GHE pH Down uses nitric and phosphoric acids to do the initial heavy lifting of altering your water pH, and the blend of both means no disturbance to your N/K ratios throughout grow and bloom - and no residue on the surface of your tank from using phosphoric alone in hard water areas. Then, with its own special characteristics, organic citric acid takes over to buffer pH changes over time, keeping your nutrient solution more stable, and helping handle calcium excesses in hard water areas.

The only dry powder pH adjuster on the market today A unique product in the industry: inert when dry, GHE Dry pH Down becomes a potent acid when mixed with water. pH regulation is an essential practice for all growers: it makes mineral salts available and stabilizes chelates, but for shops who offer mail order, sending liquid acids by post can be a risky matter - sometimes restricted by postal authorities. GHE Dry pH Down avoids these problems making shipping and transport much easier. As well as adjusting pH regulation, GHE Dry pH Down can be used (at high concentration) to clean and disinfect lines and systems, at low concentration use as a foliar spray to clean pesticide residue from leaves, and finally, it also gives a nutritive boost to plants by providing: Nitrates, in a form that supports growth without compromising flowering. Phosphates for strong flowering, root health, lush foliage and harmonious growth. 

Essentials® micro and sub micro elements All GHE nutrients contain a full spectrum of nutrients down to trace - but not all nutrients go that far. So for Non-GHE users who want to grow crops with a full nutrient compliment GHE created Essentials. This unique product is a comprehensive concentration of high quality micronutrients in chelated form, plus essential sub micro nutrients and an organic buffer: perfect for adding missing trace elements to a non GHE grow, or as a foliar treatment in areas such as aquaponics where micro-nutrients cannot be added to system water. Warning: Do not use Essentials with GHE nutrients.

Fulvic (formerly Diamond Nectar) natural bio-stimulator The biggest boost you can give your plants after nutrients is a high quality Fulvic acid, and DiamondNectar® was the best in the world. Out of the Humic family of compounds, Fulvic acid does the real heavy lifting by making minerals more easily absorbed by plants: making nutrients more effective. GHE analysed and tested over 300 different sources from around the world to give their proprietary, pH balanced, fulvic acid the maximum agronomic benefits: Better root development, earlier harvests, healthier, disease resistant plants, enhanced quality of flavour and fragrance, and increased essential oil production and significantly higher yields. What could they do better? Well their agronomist found an even more concentrated source, with added humates!
