Planting tray: A specialized container designed for starting seeds or propagating plants. These trays typically feature multiple compartments or cells, allowing for organized planting and easy transplantation of seedlings. Planting trays provide a controlled environment for germination and early growth, with features such as drainage holes and humidity domes to promote healthy development. They are commonly used in greenhouse, nursery, or indoor gardening settings to efficiently grow a large number of plants from seeds or cuttings.
