These bathtub container gardens, on wheels, are made by a Canadian company out of 100% recyclable polyethylene plastic. The Mobile Garden is large enough to grow herbs and vegetables, and because it is on wheels, the bathtub planter can be moved easily around the deck or patio, in or out of the sun. 

Each planter is equipped with threaded drainage holes, or ports. The ports allow multiple planters to be connected with garden hoses for easy watering, draining, or integrating hydroponic gardens.
