YielixPlan, Build, and Optimize Your Greenhouse Operation
Greenhouse growing gives you control over the growing environment, but that control comes with costs — heating, ventilation, CO₂ management, and the capital investment itself. These calculators help you model the economics before you build and optimize operations once you are running. Start with the heating cost calculator to compare covering materials and fuel types, then use the fan sizing calculator to spec ventilation that keeps temperature and humidity in range.
On the investment side, the greenhouse ROI calculator builds a year-by-year cash flow projection showing payback period and cumulative return. If you are considering supplemental CO₂, the CO₂ enrichment ROI calculator estimates the yield increase required to break even and projects the net return at your crop value per square metre.
Each tool uses standard greenhouse engineering formulas — U-value heat loss equations, volumetric air exchange calculations, and discounted cash flow analysis — so you can cross-check results with suppliers, extension agents, or consulting engineers. Browse the task groupings below to find your starting point, or explore all four greenhouse calculators and three planning guides.
Common Greenhouse Tasks
Estimate Heating and Climate Costs
Calculate seasonal heating costs from cover material U-value, glazing area, heating degree days, and fuel type. Compare single-poly, double-poly, and glass options.
Size Ventilation Systems
Determine required ventilation CFM or m³/h for your greenhouse volume and target air exchange rate. Ensure adequate cooling and humidity control.
Analyze Investment Returns
Calculate greenhouse ROI, payback period, and year-by-year cumulative cash flow. Evaluate whether CO₂ enrichment delivers a positive return at your yield levels.
