Yield estimator & production planner

Yield is growth rate × time × area, discounted to the part you can sell. From one cycle, the planner rolls forward: how many cycles the calendar allows, and what the year is worth at your price.

Growth rate is the whole game — it swings with light (DLI), CO₂, temperature, and cultivar, so treat this as a planning envelope, not a promise. Revenue here is gross: no seed, nutrient, labor, or electricity costs are subtracted.

Is your light actually delivering the DLI this assumes? Check PPFD & DLI →
