Atami ATA Calmag is a concentrated calcium-and-magnesium additive with iron for growers using soft, demineralised or otherwise calcium- and magnesium-poor water. It can be added to a regular feeding programme across soil, coco and hydroponic substrates. Choose one 250ml, 1L or 5L bottle per purchase.
Why Choose ATA Calmag?
ATA Calmag provides a measured calcium-and-magnesium supplement without replacing the base nutrient programme. It is especially relevant when the starting water contains little calcium or magnesium, including soft, reverse-osmosis or demineralised water.
Use it alongside a suitable base feed from our plant nutrient range, compare other products in Nutrients and Amendments, or browse the full Atami collection.
Key Features
- Supplies additional calcium and magnesium, with iron.
- Designed for water with low calcium and magnesium content.
