Description
Reinforce cell walls and keep water moving where it should
Canna Calcium is a liquid 15% calcium mono nutrient that stabilises plant tissue from the cell up. Calcium locks the cell wall together, influences growth hormones and regulates the transport of water and nutrients through the plant. Supplied in liquid, chloride-free form, it's absorbed directly so tissue is strengthened without delay – ideal for correcting a deficiency or supporting fast growth.
Key Benefits
- 15% calcium, chloride-free, for targeted correction or supplementation
- Stabilises cell walls for stronger stems and structure
- Regulates water and nutrient transport around the plant
- Influences growth hormones tied to healthy development
- Directly absorbed liquid for immediate tissue reinforcement
Weak stems and stalled transport?
A calcium shortfall weakens cell walls and disrupts how the plant moves water and nutrients, showing as soft stems, leaf-tip issues or uneven growth even when everything else is dialled in. Canna Calcium corrects that deficiency at source, rebuilding structural strength cell by cell.
How to Use
- Standard rate: 1–2ml per litre (10–20ml per 10L, 1:1000 to 1:500)
- Use the higher rate to correct a known deficiency, the lower rate as ongoing support
- Do not mix in concentrated form with phosphate-, citrate- or sulphate-containing products – add separately to the diluted solution
- Introduce gradually, then check and adjust pH after mixing
