PEAT SUBSTRATES: WHAT IS WORTH PAYING ATTENTION TO?
For germination and cultivation of plants, not natural, but processed peat with the right pH, a certain amount of fertilisers and other ingredients is used. Such substrates are the most effective growing mediums – they retain moisture well, are fluffy, light, porous, and it is convenient for plants to send forth roots and stems.
Substrates containing black peat have more humic and fulvic acids, thus stimulating plant root development more, and dark peat retains moisture and nutrients better.
For seedlings growing, fine-structured substrates shall be choosed, depending on climatic conditions, technology and the plants grown, it is best to choose a mixture with black and light peat. Light peat is more porous and, when mixed with black peat, provides the best air permeability and water absorption.
