π¬ Who Is This Suite For?
Smart Farm Engineering Lab is a free, open-source suite of high-precision online calculators built for greenhouse growers, CEA (Controlled Environment Agriculture) designers, horticultural researchers, and agricultural engineers. Unlike generic farming apps, every tool here is grounded in peer-reviewed biophysical and thermodynamic models β from the Tetens equation for Vapor Pressure Deficit (VPD) to the Penman-Monteith transpiration model and EN 1452 pipe sizing standards.
β‘ What Problems Do These Tools Solve?
- VPD Calculator β Prevent condensation-induced fungal outbreaks and optimize stomatal transpiration for maximum nutrient uptake.
- Mixing Valve Sizer β Select the correct Kv coefficient and DN pipe diameter for hot water heating loops without expensive engineering consultations.
- Fertigation Solver β Avoid chemical precipitation (salt lockout) by calculating exact raw fertilizer weights and acid neutralization volumes for your stock tanks.
- Heat Loss Estimator β Determine maximum heating load (kW) based on your specific cover material U-values, wind speed, and target indoor climate.
- Boiler vs Heat Pump ROI β Quantify the payback period for switching from fossil fuels to agricultural heat pumps with real energy price inputs.
- Crop Diagnosis & Bee Safety β Identify crop diseases and pests by symptom scouting, then check pesticide bee toxicity and Safe Re-entry Intervals (REI).
- Vertical Farm DLI β Calculate Daily Light Integral targets, LED PPFD requirements, and thermal dissipation loads for indoor vertical farming operations.
