Peat Substrates: How Structure, Components and Crop Use Shape Professional Growing Media

A professional peat substrate connects a defined peat structure with the physical, chemical and operational needs of a crop program. Perlite, wood fiber, coir, bark, clay, fertilizer and wetting agents can change air capacity, moisture distribution, drainage, handling and crop management. Commercial buyers should therefore compare finished growing media, base mixes and raw peat materials according to intended use rather than ingredient names alone.
