Description

When your plants need a little extra of one specific nutrient, Canna Mono delivers a clean, precise solution. These highly concentrated, single-element (or trace-mix) nutrients let you correct deficiencies or fine-tune feeding without disturbing the rest of your nutrient programme. Ideal for growers using soil, coco, hydro or mixed-media setups.

read the full product overview here...

Canna Mono is not a full-spectrum fertiliser: each bottle contains one key nutrient (or a trace-element blend), such as Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Iron or a Trace Mix.
This targeted approach allows you to address specific nutrient shortages, for example a magnesium or iron deficiency, without oversupplying other elements. It’s particularly useful when using purified or RO water, re-using substrate or running specialised nutrient programmes.
Canna Mono is fully compatible with Canna base nutrients (such as Coco A & B, Terra or Hydro) and other nutrient lines, making it a flexible add-on for both new and experienced growers.

Key Features & Benefits

  • Precise Deficiency Fixes: Supplies a single nutrient or trace-element mix, ideal for correcting deficiencies without upsetting overall nutrient balance.
  • Boosts Specific Growth Needs: Nitrogen supports leafy growth, Potassium strengthens cell walls, Magnesium and Iron support photosynthesis, while Trace Mix aids enzyme activity and plant health.
  • Enhanced Nutrient Control: Allows fine-tuning of nutrient ratios, especially useful with RO or soft water, coco, hydro or custom feeding programmes.
  • Compatible With All Media Types: Suitable for soil, coco coir, hydroponics, rockwool and mixed-media systems.
  • Supplement Rather Than Base Feed: Designed to work alongside a complete nutrient programme rather than replace it.
  • Ideal for Rescue or Targeted Boosts: Useful when plants show deficiency symptoms, after lockout issues, or to support specific growth phases.

How to Use

  • Identify the deficiency first by observing plant symptoms and confirming which nutrient is lacking.
  • If nutrient imbalance or pH issues are suspected, consider flushing the medium with plain water before application.
  • Mix at approximately 10 to 20 ml per 10 L of water (around 1 to 2 ml per litre), depending on the product and severity of deficiency.
  • Add to your regular nutrient solution and mix thoroughly. Avoid mixing incompatible concentrates directly.
  • Monitor plant response and return to standard feeding once symptoms improve.
