Nitrogen, phosphorus, iron, and manganese, as well as all essential micronutrients, are released from the capsules over a period of 1–2 months. Place the capsules near the roots of large, individual plants and plants with strong root systems.

The capsules do not break down completely, and the small pellets inside the capsules will remain in the growing medium even after all nutrients have been released. The pellets are made of resin, which is biologically harmless.

The nutrient capsules contain nitrogen, phosphorus, iron, and micronutrients.

The nutrients are released slowly as the plants need them.

Use nutrient capsules for stem plants, Cryptocoryne, Echinodorus, Vallisneria, and others—all plants with strong roots.
