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. Protect (formerly G.H. Protect) concentrated plant protection TA Protect strengthens a plant’s  immune system repelling insects by increasing the production of alkaloidal repulsive saps in the leaves and flowers. Apply as a foliar spray up to early  flowering. Fully organic.

 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.

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!
