Canna Terra (soil). Canna Terra Vega is the one-part growth feed for soil and potting mixes. Canna Terra Flores is the flowering feed, made to work with soil's tendency to hold on to nutrients so phosphorus, potassium and trace elements stay available to the plant.

Canna Bio (organic soil). Canna Bio Vega and Canna Bio Flores are certified organic one-part liquid feeds for soil, Bio Vega for the vegetative stage and Bio Flores for flowering.

Canna Coco. Canna Coco A+B is a two-part feed made for coco coir.

Canna Aqua (hydro). Canna Aqua Vega A&B and Canna Aqua Flores A&B are two-part base feeds for growth and flowering in recirculating systems such as NFT, ebb and flow and DWC.

Starting off. Canna Start is a gentle one-part feed for seedlings and cuttings. Canna Rhizotonic is an algae-based root stimulator for new plants, transplants and plants recovering from stress.

Flowering. Canna Boost is a flowering stimulator that works alongside your base feed. Canna PK 13/14 adds extra phosphorus and potassium during flowering.

Root zone and finishing. Cannazym uses enzymes to break down dead roots and keep the root zone clean. Canna Flush cleans the substrate before harvest without killing beneficial bacteria and fungi.

Canna Mono, CalMag and Silica. Single-nutrient bottles to correct a specific shortage: Nitrogen, Phosphorus, Calcium, Magnesium and Iron. Canna CalMag Agent tops up calcium and magnesium for soft tap water or RO water. Canna Silica strengthens cell walls against heat, wind and drought.

Leaf protection. Canna Cure and the ready-to-use Canna Cure RTU are leaf sprays that help deal with spider mite and mildew.

Growing media. Terra Professional 50L and the nutrient-enriched Terra Professional Plus 50L soils, Coco Professional Plus 50L buffered coco and Canna Aqua Clay Pebbles 50L.

Which Canna nutrients do I need?

Soil. Use Terra Vega then Terra Flores, ideally in Terra Professional or Terra Professional Plus. For a fully organic approach, use Bio Vega then Bio Flores. See our soil range.

Coco. Use Coco A+B with Coco Professional Plus. More options are in our coco coir collection.

Hydro. Use Aqua Vega then Aqua Flores in recirculating systems. Clay pebbles suit hydro, ebb and flow and drip systems.

Additives by stage. Canna Start and Rhizotonic early on, Cannazym throughout, then Boost and PK 13/14 in flowering, and Flush before harvest.
