Terra Aquatica pH+ 500 ml – pH increaser for irrigation water and nutrient solutions
Terra Aquatica pH+ 500 ml is a concentrated pH increaseris a concentrated pH increaser that raises the pH of irrigation water and nutrient solutions and helps keep the plant-growing environment within a suitable range. The product is suitable for use in hydroponics, coco coir and soil and is especially useful with soft or reverse-osmosis (RO) water (RO filtration removes almost all minerals, salts, chlorine and other impurities from tap water, producing nearly pure water with an EC close to zero).
In addition to adjusting pH, T.A. pH+ contains plant-available silicate, which helps supplement silicon that is often deficient in hydroponic growing systems.
Why choose Terra Aquatica pH+?
The correct pH directly affects how well a plant can absorb minerals from a nutrient solution. If pH is too low, some nutrients required by the plant can become less available.
T.A. pH+ raises and stabilises pH in a controlled manner.
Key benefits:
- effectively raises the pH of irrigation water and nutrient solutions pH level;
- particularly suitable for use with soft and RO water ;
- contains plant-available silicate;
- helps maintain optimum nutrient availability;
- suitable for hydroponics, coco coir and soil;
- concentrated and economical;
- suitable for use throughout the growing cycle.
The importance of pH in plant growing
Nutrient uptake depends heavily on the pH of the growing environment. Terra Aquatica recommends a generally safe pH range of approximately 5.5–6.5, with the lower end of the range generally preferred for hydroponic solutions.
pH+ allows the pH of an overly acidic nutrient solution to be raised gradually, creating a more suitable growing environment for plants.
Particularly suitable for soft and RO water
High pH is more common with hard water, but very soft or reverse-osmosis water can create the opposite problem: the nutrient-solution pH may be too low.
In this situation, Terra Aquatica pH+ helps Terra Aquatica pH+ raise pH to the desired range.
Contains beneficial silicate for plants
T.A. pH+ is more than an ordinary pH regulator. It also supplies plants with available silicate, which may be deficient in hydroponic systems because water naturally contains little silicate.
This makes pH+ a practical solution both for correcting pH and supplementing the silicate content of a nutrient solution.
How to use
Add T.A. pH+ to irrigation water or a prepared nutrient solution in small amounts.
- Add a small amount of pH+ solution.
- Mix the nutrient solution thoroughly.
- Measure the pH again.
- Repeat as necessary until the desired pH is reached.
Because pH+ is highly concentrated, adding a large amount at once is not recommended. The required dose depends on the water’s initial pH and mineral content and on the nutrient solution being used.
