pH Plus (25%) 1 Liter Plagron is a concentrated liquid corrector designed to raise the pH of irrigation water and nutrient solutions. It allows you to maintain appropriate values to promote balanced nutrient absorption in indoor cultivation.

pH control is essential to achieve stable plant development, especially when using mineral fertilizers, hydroponic systems, coco fiber, or low-mineralization water. pH Plus (25%) 1 Liter Plagron allows you to gradually increase the pH level when the nutrient solution is excessively acidic.
Proper correction helps keep essential elements such as phosphorus, calcium, magnesium, potassium, and other necessary nutrients available during the growth and flowering stages.
The concentrated formula contains 25% potassium hydroxide, so it should be added in small amounts and always after incorporating fertilizers into the water. The use of a calibrated digital meter allows you to check each adjustment and avoid sudden changes.
This corrector can be used in soil, coco, and hydroponic crops, as well as integrated into tanks, drip irrigation systems, and manually prepared nutrient mixes.
Thanks to its alkalizing action, the product makes it easier to keep water within an appropriate range for each indoor growing method.
pH Plus (25%) 1 Liter Plagron is used to raise the pH of irrigation water when the value obtained after mixing nutrients is too low. Many fertilizers reduce the initial alkalinity of the water and can bring the solution to acidity levels that are not suitable for the roots. When this happens, certain nutrients remain present in the tank, but the plant has difficulty assimilating them properly.
The corrector allows for a precise pH adjustment, helping to avoid nutrient lockout, mineral imbalances, slow growth, leaves with abnormal coloring, or irregular responses during flowering. In soil and coco, a value adapted to the substrate and fertilization program is usually sought. In hydroponics, control must be even more precise, since the roots are in direct contact with the nutrient solution.
It is also practical in crops that use reverse osmosis water or low-mineralization water. These waters have little buffering capacity and can experience rapid changes when adding nutrients, stimulators, or additives. With small corrections using Plagron pH Plus, it is possible to restore the appropriate value before starting irrigation.
Before using the product, prepare the irrigation water by incorporating the fertilizers, stimulators, and supplements planned for that application. Next, it is recommended to mix the solution well and measure the pH with a calibrated device. The corrector should only be added when the value is below the level intended for the type of crop.
As a general reference, an initial amount of up to 0.5 ml per liter of water can be added, applying it gradually. After each small dose, it is necessary to stir the mixture, wait a few moments, and measure again. This procedure should be repeated until the desired level is reached, avoiding adding large amounts at once.
The actual dose may vary depending on water hardness, tank volume, fertilizer concentration, and initial pH. For this reason, measurement is more important than a fixed dose. In many crops, work is done within an approximate range of pH 5.5 to 6.5, although the specific value should be adapted to the substrate, development stage, and nutritional program used.
It is advisable to shake the container before use and wear gloves and protective glasses during handling. The product is concentrated and should be kept out of reach of children and pets. It should also not be mixed directly with undiluted concentrated fertilizers. Incorporation should always be done into the already prepared irrigation water.
The composition of pH Plus (25%) 1 Liter Plagron is based on 25% potassium hydroxide (KOH). This alkaline compound increases the pH of the nutrient solution and provides potassium, an element involved in numerous physiological processes in plants.
The formulation has a nutritional indication of NPK 0-0-25. The absence of nitrogen and phosphorus allows the product to be used as a regulator without significantly altering the main fertilization program. Even so, due to the potassium concentration, it is important to respect the necessary amounts and avoid excessive corrections.
Potassium hydroxide offers rapid action and allows pH to be modified with small amounts. This feature makes the product a practical option for tanks of different capacities, as long as the adjustment is made with a reliable meter.
pH Plus (25%) 1 Liter Plagron is a liquid alkaline regulator developed to correct irrigation solutions that are too acidic. The one-liter format is designed for growers who prepare nutrients frequently and need to have a concentrated corrector for different phases of the cycle.
It can be used during vegetative growth and flowering, both in small installations and in rooms with larger tanks. Compatibility with soil, coco, and hydroponics makes it easy to integrate into different indoor growing methods. It can also be used with automated irrigation systems, as long as the product is completely diluted before activating the installation.
pH stability prevents the availability of nutrients from changing suddenly. A balanced solution allows the roots to work in more favorable conditions and helps maintain consistent nutrition throughout the cycle.
The main benefit is being able to raise the pH in a controlled way when fertilizers have reduced the initial value too much. Keeping the water within the recommended range promotes the absorption of macro and micronutrients, reduces the possibility of nutrient lockout, and helps achieve a more uniform response.
Another highlight is versatility. The product can be used in soil, coco fiber, hydroponics, and drip irrigation systems. The 25% concentration allows for numerous adjustments with a small amount, offering good performance per container.
Proper use also makes crop monitoring easier. When the pH remains stable, it is easier to interpret electrical conductivity, observe the nutritional response, and detect possible problems related to water or fertilization. Constant control can promote vigorous growth, active roots, and more balanced flowering.
The price of pH Plus (25%) 1 Liter Plagron can be checked directly on the Hydroponics Blanes product page. The concentrated format offers long-lasting use, as each adjustment usually requires small amounts. The final performance will depend on the initial pH of the water, the amount of nutrients added, and the volume prepared for each irrigation.
In the online Plagron fertilizer catalog you can also find fertilizers, stimulators, additives, and products for parameter control. Combining proper nutrition with regular pH and EC measurements allows for more precise crop management.
