Use your measurements
Start with greenhouse dimensions, sensor readings, crop category, and lighting schedule.
Practical digital tools for everyday life
Business software for growing organizations
Free, fast, and easy to use
Turn your greenhouse measurements into an understandable climate, light, and airflow plan—without uploading grower or crop-batch details.
Start with greenhouse dimensions, sensor readings, crop category, and lighting schedule.
VPD, DLI, volume, and air-exchange reference are visibly calculated from those inputs.
Use results to frame questions, then confirm with crop guidance and equipment documentation.
For a 10 m by 5 m greenhouse with a 3 m average height, the tool calculates 50 m² of floor area and 150 m³ of air volume. With a 250 µmol/m²/s supplemental PPFD setting for 12 hours, the displayed DLI is 10.8 mol/m²/day. The airflow reference is simply 15 times air volume per hour; it does not select equipment or replace a ventilation design.
Compare entered temperature and humidity conditions with a transparent planning baseline.
Focus on DLI and airflow planning from greenhouse dimensions.
Translate crop-water assumptions into a scheduled water estimate.
Review nutrient-label arithmetic separately from climate planning.
Plan crop batches and timing after defining growing conditions.
It turns entered dimensions, climate targets, humidity, and light values into floor area, air volume, VPD, DLI, and a planning airflow reference.
No. It is local planning arithmetic using the values you enter.
Vapor-pressure deficit is calculated from the entered current temperature and humidity. It is a planning indicator, not a crop prescription.
The tool multiplies entered supplemental PPFD by lighting hours and converts the result to mol/m²/day.
The greenhouse air volume is multiplied by a transparent 15-air-changes-per-hour planning reference. It is not fan or HVAC sizing.
Yes. The tool converts entered feet to metres internally for the displayed area and volume calculations.
No. Broad category bands are only prompts for verification; variety, crop stage, disease pressure, and local conditions matter.
Yes. CSV and printable PDF exports use the exact local calculation displayed in the result panel.
No. This tool runs in the browser and does not send entered values to Rigid Apps servers.
Confirm calibrated sensor readings, crop-stage guidance, equipment specifications, electrical and structural requirements, and local rules.
