Sector

While most of the terms used to describe areas or subsets of a greenhouse\, like phase or section\, typically refer to sets of paths\, a sector defines an area that runs perpendicular to paths. For example\, there may be four sectors on either side of the centre path of the greenhouse\, with sectors labelled as A\, B\, C and D. The sector can then be used to describe a location within a given path or bay.
