Houseplant fertilisers

The right plant food depends on how your plants grow. Complete liquid feeds are available for houseplants in soil, while CANNA Coco A+B and other coco-specific products are designed for plants grown in coco. Hydroponic nutrients such as CANNA Aqua Vega and HESI Hydro Growth serve water-based growing systems.

You can also find CalMag products, silicon supplements, enzymes, root treatments and pH adjusters for more specific needs. A complete base feed supplies essential nutrients; additives are selected according to your water, growing medium and plant. Follow the dilution and feeding guidance on each product, especially when combining concentrates.
