  1. Object
    1. earth & plastic greenhouses = earth wall structure with plastic cover (semi-permanent), plastic may be opened during hot season.
    2. glass or plastic greenhouses = permanent glass or plastic/metal structure: does not include temporary plastic/metal greenhouses.
    3. open-air horticultural area = non-enclosed permanent structure open to sky, used for production of plants in pots or other artificial media, not in soil.
    4. roofed horticultural area = permanent roof-covered (rain does not penetrate), but not fully-enclosed structure, used for production of plants in pots or other artificial media, not in soil.
  2. Modifier 1 (structure type)
    1. permeable floor = floors of earth, may be compacted or covered with permeable temporary surface with some water penetration.
    2. sealed floor = floor covered by permanent impermeable surface such as concrete or heavy plastic.
  3. Scale
    1. small <30 m
    2. large >30 m
