A planting tray is a shallow container used for starting seeds or growing small plants. It typically has multiple compartments or cells, allowing gardeners to plant several seeds in one tray. These trays are often made from plastic or biodegradable materials and can be used indoors or outdoors. Planting trays help maintain moisture and provide a controlled environment for seedlings. They are commonly used in conjunction with seed starting mix and can be placed on a windowsill or under grow lights. Using a planting tray makes it easier to manage young plants before transferring them to larger pots or the garden.
