Peat fines are used in growing media for small cell propagation, seed germination and plug production. Grower Grade, sometimes called coarse grade peat moss, has long, blond-colored fiber and is generally used to produce growing media for greenhouse plant production and nursery crops grown in flats to larger pots and baskets. Due to the fiber size, growing media produced with this grade of peat will have many smaller pore spaces and a slightly lower water holding capacity, slightly higher bulk density and a slightly lower air porosity than growing media made with grower grade peat. Since the fibers are almost non-existent due to complete decomposition, the fine particles in black peat pack tightly together. These prevent the cells from collapsing when they dry out. When used in soil, peat moss consists of the partially decomposed remains of several types of moss. Due to its higher air porosity, plant roots can obtain oxygen more easily for maximum growth rates, further using up water from the growing medium and causing it to dry out more rapidly than growing media with finer peat moss. Undecomposed Sphagnum has also been used to improve the quality of peat-based Good quality sphagnum moss will be pure moss, without any other plant material incorporated. The medium seems suboptimal for, for example, S. subnitens, the species with the highest productivities out of 31 peat moss species from Sphagnum‐dominated wetlands (Gunnarsson, 2005). An important characteristic of the sphagnum cells is that they have lignified walls in the form of rings, spirals or plates. The lack of efficient harvesting technology has restricted the use of Sphagnum biomass as a growing medium constituent.
