Growth Media
Growth media, also known as growing media or plant substrate, is the material that plants grow in, replacing natural soil in commercial horticulture. It's like a special soil mix designed to give plants the best growing conditions. This could include materials like peat moss, coconut coir, vermiculite, or other substances that help with water retention and root growth. When you see this term in resumes, it usually means the person has experience managing or working with professional plant growing materials in settings like greenhouses, nurseries, or hydroponic facilities.
