Plant Sitter by Gardener’s Supply Company

Let Plants Water Themselves
Busy gardeners love the Plant Sitter system. It delivers water to your plants based on the soil's dryness. Each Plant Sitter includes a small water tank that hangs on the side of your pot, and one 4-1/4" H x 1-1/2" dia ceramic cone with 18-1/2" siphon tube. Additional cones with watering tubes are also available separately.

• Large planters may require 2 or more cones.
• Reads soil dryness so plants are never over- or underwatered.
• A Vacation Watering Solution!
