Measuring 48cm (19) x 66cm (26) x 27cm (10) deep, these self-watering planters are a foolproof way to grow bumper crops of tomatoes & other vegetables in a small space. The heart of the system is the 4 gallon water reservoir, accessed by the handy fill & drain opening, which provides a steady supply of moisture to plants. Kit comes complete with sturdy two-part stacking support frame (which folds flat for easy storage) & clips to secure it to the planter, providing support up to a height of 82cm (32).
