Ideal for STEM in Early Learning! Our mobile garden center brings nature into the classroom and engages children in hands-on learning about how plants grow when they plant seeds, water the soil and follow the evolution of plant life. Stylish, sturdy and mobile, the cabinet features a top shelf that accommodates 28 included clear plastic planting containers, a middle shelf with a vertical center divider that creates a storage compartment on each side, and a bottom shelf compartment that accommodates two Gratnell trays with lids [included] to store additional materials such as seeds, plants or soil [not included]. Mounted on four heavy duty non-marking lockable casters for mobility, the 19.5"W cabinet easily fits through standard door openings. Need a planter stand instead? Check out our WB2450 Nature
