Grow propagation light schedule calculator

Calculate lighting timetable [ID,day,on hour,off absolute hour] and total electrical energy with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use lighting timetable [ID,day,on hour,off absolute hour] and total electrical energy to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Lighting timetable [ID,day,on hour,off absolute hour]

Repeat supplied daily schedule for each batch; off may exceed24 into next day.

Total electrical energy (kWh)

Sum days×daily hours×power/1000; no crop photoperiod recommended.

Assumptions & limits

Assumptions & limits

  • User-chosen photoperiods, batch dates, fixture slots. Returns Lighting timetable and energy. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
