TIERRA garden GP70 Large Self-Watering Tray, 23 in L, 15-1/2 in W, Green

This large self-watering tray ensures plants are watered automatically for up to 14 days. Doesn't overwater and is the ideal plant sitter and works great as a vacation watering system. The unit features a base reservoir tray which contains a 'stilted' inner support platform which is covered in capillary matting. The base tray provides a reservoir of over 2 gal. By ensuring the exposed compost at the bottom comes in contact with the capillary matting the plants will water themselves.
