This is my optimized version of a flower top for the windowsill. At some point the plants get bigger but the windowsill doesn't grow with them. That's why I designed this rectangular pot. This gives the plant much more space without the pot protruding over the edge.
The flower pot consists of two parts. The inner pot has holes that prevent too much water from collecting. The excess water is drained into the planter.
The dimensions are approx. 24cm x 15cm and 16cm high.
