Gardener's Supply Company Aqua Cones are colored ceramic self-watering devices that use 1-liter or 2-liter plastic bottle reservoirs to support moisture in potted plants.
A user reported a negative experience, describing the Aqua Cones as poorly designed because standard 2-liter bottles did not fit securely into the cones, causing them to tip over when filled with water.
