Seedling trays are a type of container used to germinate and grow young seedlings. They are designed with small compartments that allow for the growth of a single seedling in each compartment. Seedling trays are typically shallow and lightweight, making them easy to handle and transport. They come in a variety of sizes and materials, including plastic, biodegradable materials, and recycled materials. Seedling trays are an important tool for gardeners and farmers who need to start plants from seed or transplant young seedlings, as they promote healthy growth and development of young plants and allow for easy organization and monitoring of individual plants.
