There are two possible solutions to this clue, both in Dutch and with 7 letters:
- AANBOUW (pronounced “ahn-bow”) – This translates literally to ” Anbau” ( Anbau is the German word for cultivation) and refers to the cultivation process happening within a structure built onto a main building.
- KASBOUW (pronounced “kahs-bow”) – This directly translates to “greenhouse cultivation” and is a more specific term for growing plants in a controlled environment like a greenhouse.
