As of 2015, prices of self-watering plant containers range from approximately $2 for a 6-inch diameter plastic pot from Home Depot to $400 for a 51-inch wicker trough planter from Gardener's Supply Company. The cost of a self-watering plant container varies greatly by size, material and brand.
Planters with a self-watering feature simplify growing for the busy home gardener. Plants in pots designed by Lechuza can go up to 12 weeks between watering.
Self-watering planters are used indoors or outside. Smaller pots are perfect for the windowsill garden. Large troughs and planters are more suitable for outdoors. Gardeners use self-watering pots to grow ornamental plants as well as fruits and vegetables.
