Description
Bring pH down without harming your root-zone biology
Canna Organo Acid is an organic alternative to Canna pH-, used to lower the pH of your water or substrate while still allowing beneficial bacteria and fungi in the root zone to flourish. Maintaining the right pH is crucial for your plant's ability to take up nutrients, and this organic acid also serves as an alternative to nitric and phosphoric acid for growers who want to avoid stronger mineral acids.
Key Benefits
- Organic pH-down solution suitable for organic growing
- Protects beneficial bacteria and fungi in the root zone
- Alternative to nitric and phosphoric acid
- Supports stable nutrient uptake by holding pH in the correct range
Is a harsh pH-down product wiping out your microbes?
Standard mineral acids correct pH effectively but tend to be hard on the beneficial biology growers work to build up in soil or coco. Canna Organo Acid corrects pH without that trade-off, keeping the microbial life in your root zone intact while still bringing values down where they need to be.
How to Use
- Mix your nutrients first, then check the pH of the made-up solution
- Add gradually, a little at a time, stirring and re-testing as you go until you reach your target range
- Typical targets: around pH 5.5-6.5 depending on medium (lower for hydro and coco, higher for soil)
- Go slowly to avoid overcorrecting, as organic acids can continue to shift readings after mixing
