My substrate is very dry and poorly takes up water, what can I do?

If peat or peat-based substrates dry out very strongly, it can be that they poorly take up water after watering. Stable drops or small puddles form on the substrate and the water pearls up. The substrate behaves hydrophobically, meaning that it "avoids water". Fine substrates, used for propagation, are more affected than coarse structures. terracult substrates contain a special wetting agent and are supplied with a certain moisture content before packaging in order to avoid this effect. It can nevertheless come to exceptions, such as the dry conditions described above.

To make the substrate water receptive again, a wetting agent should be added when watering, according to the application recommendations. There is an advantage of using warm water with a temperature between 20°C and 30°C. Another possibility is the contribution of a certain amount of water before processing sacks or big bales that are still closed.
