The Natural Control grow boards have been made by compressing dried substrate material. The compression enables better durability during transportation. Dried compressed boards are lighter and smaller which makes them easier and cheaper to handle and to transport. The following instructions will explain how the dried and compressed boards should be expanded with a fertiliser solution before planting.
Sometimes, in certain temperatures, water condensates between the peat bale and the plastic wrapping creating conditions that allow fungal growth. You may see white mould or yellow or orange powdery like growth on the surface of the peat. These fungi are not harmful to plants.
Compressed peat based growing media require some loosening and preparation before taking them into use.
To ensure an optimum moisture content for filling pots and trays, you can conduct a simple check of the moisture level by hand.
