Watering calculator
Pick a plant, tell me the pot size, the light and the season, and I give you a quantity and an interval — plus the calculation behind them.

How it works
The base quantity and the base interval come straight from the plant's page, where they were set with its species. The tool then applies three corrections: the pot, compared with the reference pot of that page; the light, using the sun and shade coefficients of the same page; and the season, because a plant in winter dormancy drinks roughly a third less often than in July. Outdoors shortens the interval again, since wind and open air dry a pot faster than a living room.
