How to Use This Calculator
- Enter the greenhouse length and width in feet, then select the structure type (Hoop House, Gutter-Connected Poly, Rigid Frame, or Glass Venlo).
- Choose the glazing material (single poly film, double poly, or polycarbonate/glass) and toggle heating, cooling, and bench systems on or off.
- Enter the site preparation cost per sq ft for grading, gravel, and utility connections.
- Review the itemized cost breakdown: Structure & Glazing, Heating, Cooling, Benches, and Site Prep.
- Use Total Cost and Cost per Sq Ft to compare structure options or phased build approaches.
