A greenhouse structure with multiple bays connected along the gutters is called

• A. Lean To
• B. Sawtooth
• C. Gutter-connected (Ridge-and-furrow)
• D. Quonset

Answer: (C)

Greenhouses structured with several bays connected along a common gutter form a gutter-connected (ridge-and-furrow) layout. This design places adjacent bays beneath a continuous series of gutters and ridges, creating a long, uniform greenhouse that shares a single climate-control and structural framework across all bays. The arrangement is efficient for heating, ventilation, and irrigation because the bays operate as a single system rather than as isolated units. A lean-to is built against a wall, so it lacks multiple connected bays. Sawtooth designs feature alternating roof pitches to maximize light access, not a gutter-connected row. Quonsets are curved arch structures, typically a single unit, rather than a series of straight bays connected along gutters.
