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.
Terra Aquatica pH- :
Premium pH management and buffering for hydroponics, coco and soil.
Not just a simple acid : Terra Aquatica pH- makes a real contribution to nutrient solution stability
To make Terra Aquatica pH- we carefully blend three acids commonly used alone in hydroponics to give you all the benefits of each – without the disadvantages.
Terra Aquatica pH- 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.
Terra Aquatica pH+ :
Premium pH management and silica source for hydroponics, coco and soil.
Controls pH and boosts 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. Terra Aquatica pH+ 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.
pH- Powder :
Unique dry powder pH management solution for hydroponics, coco and soil.
The only dry powder pH adjuster on the market today
A unique product in the industry : inert when dry, Terra Aquatica pH- Powder 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. Terra Aquatica pH- Powder avoids these problems making shipping and transport much easier.
As well as adjusting pH regulation, Terra Aquatica pH- Powder 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.
HOW TO USE :
Warning: Always wear appropriate protection when handling strong acids/alkalis.
To adjust pH
Add to water or nutritive solution as required. Re-test pH and adjust as necessary.
pH- Powder :
Add 1 gram per 5 or 6 litres of water and mix well. Test pH and adjust accordingly more or less pH down or fresh water.
To clean lines and systems : Add 1 gram per litre of water, let system run overnight, then rinse well with water.
As a foliar cleaner : Use 1 gram per 10 litres of water.
