An OpenFab original! The Wise Planter is a post-smart planter. No gadgets, no sensors, no batteries. Basic physics lets you visually assess the needs of your favorite desktop plants.
The inner pot sits on a high quality spring which rests against the outer base. As the soil loses moisture, the pot slowly rises while the base remains in place. This is a variation of the original Wise Planter. Intersecting geometry provides a window through the base that exposes the pot inside. Instead of an adjustable trigger, there’s a color change on the pot. When you water — more blue is exposed. Gradually blue is lost, visually representing the loss of water.
