A modular hanging planter that you can customize for your needs.

There are several mounting options:
Four hooks from 20 to 50 mm in diameter for curtain rails
A ceiling mount to be used with screws or wall mount tape (diameter of the two screw holes 5,5 mm)
A wall mount to be used with screws or wall mount tape (diameter of the two screw holes 5,5 mm)
