The goal was to compare the costs of different greenhouse designs on a computer program for areas from 100 to 750 square meters. They used a special program to calculate materials needed and total costs for steel greenhouses with various roof types. The program lets users pick different greenhouse options to view the cost calculation and make changes if needed. Different greenhouse sizes and materials for growing four types of plants were considered. The study found that costs varied based on greenhouse size, roof type, and materials chosen for cultivation of different plants. By using the computer program, manufacturers can pick the best greenhouse type and cost for the plants they want to grow.
