Canna Nutrients

Canna nutrients are the world’s most widely trusted brand in professional hydroponics, used by commercial growers and dedicated hobbyists across more than 100 countries. Developed in the Netherlands with decades of horticultural research behind every formula, Canna produces scientifically precise nutrient ranges for every growing medium — from rockwool and coco to organic soil and deep water culture. At The Horticulture Company, we stock the full Canna range for UK growers.
Canna Base Nutrients — Medium-Specific Formulation
Canna’s most important characteristic is their commitment to medium-specific formulation. Rather than a single universal nutrient, Canna produces distinct base nutrients for each substrate type. Canna Coco A&B is specifically designed for coco coir, with elevated calcium and magnesium levels that compensate for coco’s high cation exchange capacity. Canna Aqua is engineered for recirculating hydroponic systems. Canna Hydro suits run-to-waste mineral systems on inert substrates. Canna Terra is developed for organic and semi-organic soil mixes.
This medium-specific approach ensures optimal nutrient availability and pH stability in your specific growing environment. Using a medium-appropriate formula eliminates many of the pH drift and nutrient lockout issues that occur when growers use a generic nutrient in the wrong substrate.
Canna Boosters and Additives
Canna’s additive range is as carefully formulated as their base nutrients. Cannazym is an enzyme product that breaks down dead root material, creating space for new root growth and reducing the risk of pathogen colonisation. Rhizotonic is an all-natural root stimulator containing vitamins and trace elements. Cannacure is a foliar spray that controls pests and improves canopy health simultaneously. PK 13/14 is Canna’s renowned PK booster — applied at weeks 4–5 of flower, it reliably drives increased flower mass and density.
