Description
The planter consists of an inner terracotta pot encased in a 3D-printed outer shell. The space between the pot and the shell acts as a water reservoir, allowing moisture to slowly diffuse through the porous terracotta into the soil.
This self-watering system is ideal for plants that require consistently moist soil and is not suitable for plants that need dry periods between watering.
