In order to lower the pH in the feeding tank there is the pH- series. There are different solutions available for the vegetative (growing) and generative (blooming) phases.
In order to adjust the pH upwards there is CANNA pH+. This product is suitable for both the growth and the flowering phase. CANNA has two different solutions of CANNA pH+. One of 5 % for small adjustments and one of 20% for larger corrections.
CANNA Organic Acid can be used as an organic alternative for CANNA pH-. 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.
CANNA pH- Grow can be used to reduce the pH value of the nutrient solution during the vegetative period.
pH- BLOOM is used to reduce the pH value of the nutrient solution during the flowering period.
Contains 41% phosphoricanhydride (P2O5)
The phase of the plant is not important if you are raising the pH with CANNA pH+. CANNA has two different solutions for raising the pH, one of 5 % for small adjustments and one of 20% for larger corrections.
potassium carbonate 5% potassium hydroxide (KOH)
13% potassiumoxide (K2O)
CANNA Organic Acid contains 50% citric 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.
