PH- Organic Acid 1 Liter CANNA is a pH regulator formulated with citric acid, designed to reduce the pH of the irrigation solution in a controlled manner. A practical option for indoor cultivation, growth and flowering, with simple and precise application.

pH control is one of the most important aspects in any plant nutrition program, as it largely determines the availability of the elements present in the water and in the nutrient solution.
PH- Organic Acid 1 Liter CANNA allows you to lower the pH when the initial value is too high, providing a more suitable environment for nutrient absorption. CANNA recommends making the correction in small amounts, mixing well, and measuring after each adjustment.
This method avoids excessive reductions and allows you to reach the appropriate value according to the growing medium.
In indoor cultivation, it is especially useful when working with irrigation tanks, mineral or organic fertilization, automated irrigation systems, coco, soil, or different technical media.
The regulation should be done after preparing the nutrient solution and never by mixing the corrector directly with concentrated fertilizers. For stable nutrition, it is advisable to check the pH with a calibrated meter before each watering.
PH- Organic Acid 1 Liter CANNA is part of CANNA's pH regulation products and is designed to lower the pH value of water or a nutrient solution. The acidifying base is citric acid, an organic acid that allows for gradual corrections. The 1 liter format is suitable for both regular users and indoor installations with tanks of different capacities.
Maintaining an adequate pH helps nutrients remain available to the roots. A value outside the appropriate range can limit the assimilation of certain elements, even if the amount of fertilizer added is correct. For this reason, measuring and adjusting the pH is part of a well-controlled cultivation routine.
This product is used to reduce the pH of irrigation water or the nutrient solution when the measured value is above the desired range. CANNA generally places nutrient availability between pH 5.2 and 6.2, with variations depending on the medium; the Organic Acid data sheet also shows a recommended working range of pH 5.2 to 6.4.
In indoor cultivation, the corrector can be used during different stages of the cycle whenever there is a need to lower the pH. The correction does not replace base nutrition: it acts as a complementary tool within the management of water and CANNA fertilizers.
The dosage indicated by CANNA is 2 ml per 10 liters of nutrient solution, equivalent to approximately 0.2 ml per liter. The actual amount needed may change depending on the alkalinity of the water, the initial pH, and the products added to the tank.
To use it correctly, first prepare the water with the planned nutrients and additives. Then measure the pH. When the value is too high, add a small amount of PH- Organic Acid 1 Liter CANNA, mix thoroughly, and measure again. If it is still necessary to lower the value, repeat the process little by little until the goal is reached.
It should not be mixed directly with concentrated fertilizers. CANNA also recommends regularly renewing the solution stored in tanks, because citric acid can promote the development of bacteria and molds when the water remains for too long. The container should be kept protected from light, above 5 °C and out of reach of children.
The formulation is based on citric acid (C6H8O7). The CANNA Germany data sheet indicates a concentration of 41% citric acid, while the CANNA UK website shows 50% for Organic Acid. Due to this difference between markets, for the unit sold, the information indicated on the original label of the container should always prevail.
Citric acid allows you to reduce the pH without resorting to correctors based on nitric acid or phosphoric acid. This makes the product an organic alternative for those seeking pH regulation based on this type of acid.
PH- Organic Acid 1 Liter CANNA is a liquid corrector intended for downward pH adjustment. It is not a base fertilizer or a stimulator; the main function is to condition the irrigation solution so that the roots find a more favorable chemical environment to take advantage of the available nutrients.
The product can be integrated into indoor cultivation routines with soil, coco, and other systems where pH control is necessary. Before adding it, it is advisable to have a reliable meter, as working without measurement can cause a greater correction than necessary.
The product works by providing citric acid to the solution, which progressively reduces the pH value. When the water starts from a too alkaline level, small amounts allow the solution to approach the desired range. The correction should always be done gradually, mixing and measuring between each addition.
An adjusted pH favors nutrient availability and helps maintain more regular nutrition. In indoor installations with tanks, this practice also allows you to repeat irrigation parameters with greater precision and better control the changes caused by the starting water or by the mixture of fertilizers.
Main benefits include precise pH adjustment, citric acid-based formulation, the possibility of using very small amounts, and compatibility with growth and flowering routines when it is necessary to reduce pH. It also helps to avoid problems related to a solution that is too alkaline, which can hinder the availability of certain nutrients.
The 1-liter format offers good duration because the usual dosage is small. For consistent results, it is advisable to periodically calibrate the pH meter and prepare each tank always following the same mixing order.
