CANNA Organic Acid can be used as an organic alternative for pH Down. It can be used to bring down the pH values in your water or substrate. Maintaining the right pH value is crucial for your plant’s ability to take up nutrients. It also serves as an alternative for nitric acid and phosphoric acid.
Bacteria and moulds thrive well on citric acid, and therefore also in the nutrient tank. Care should be taken to refresh the solution in the tank on a regular basis.
