This is the garden that rolls to and fro, creating a versatile mobile plant bed for a patio or sun room. The planter wheels easily on four smooth-rolling casters, enabling gardeners to position plants for optimal sun during the day, or to relocate delicate seedlings indoors on a chilly night. The polyethylene garden bed features double-wall construction that slows the transfer of heat to prevent soil from drying out. The durable material also resists scratches, dents, and fading from exposure to the sun's damaging UV rays. Two threaded drain plugs in the bed's bottom can be attached to a garden hose to direct excess water away or sealed when used indoors. Brakes on the casters keep the planter rooted to the spot when desired. Supports up to 165 lbs., Assembly required. 39 1/2" L x 23 1/2" W x 14" H. (21 lbs.)
