Calculation method
Calculation method
Benches in selected uniform grid
Compare the two uniform orientations after reserving perimeter clearance and aisles; choose the larger count, retaining the entered orientation on ties.
Bench orientation along length, width (m)
Dimensions in the selected orientation; no mixed packing.
Grid columns, rows
floor((usable length + aisle)/(bench length + aisle)) and the corresponding width count.
Total bench growing area (m²)
Bench count × individual bench area.
Unused inner greenhouse area (m²)
Inner greenhouse area − bench area; includes aisles and edge clearance.
