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 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.

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.

 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.

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 Bloom (formerly G.H. Bloom) ultra-concentrated root booster By promoting balanced nutrient  delivery and stimulating flowering,  TA Pro Bloom can add up to 20% in dry weight to flowering plants.  Like Pro Roots, TA Pro Bloom is  super concentrated (0.1ml/L), fully  organic, and also stimulates beneficial  microorganisms to further enhance plant growth.
