In summary, the grade of sphagnum peat moss used to produce soilless growing media will greatly influence the bulk density, water holding capacity and air porosity which will determine the use of growing media in plant production. The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. This sterilized medium is becoming more widely used. This limits air flow, which limits movement of water vapor, causing this type of sphagnum peat moss to dry out very slowly between waterings. Plants grown in cocopeat and coconut husk chips were on par with an … Medium for planting: peat moss serves as a good transplanting medium for planting seedlings, or growing in containers. It looks similar to coarse peat as it still has decent fiber, but does have slightly lower air porosity and water holding capacity as well as a little higher bulk density than fine peat moss. The grade or particle size of the peat moss influences the amount of pore space in a soilless growing medium. LEFT A phalaenopsis plug grown in sphagnum moss showing white, healthy roots (Texas A&M University). But the presence of natural, beneficial microorganisms in Sphagnum peat moss is essential for a healthy crop. Since the fibers are almost non-existent due to complete decomposition, the fine particles in black peat pack tightly together. Peat fines are used in growing media for small cell propagation, seed germination and plug production.
