Methodology, data sources & the Building 1411 apparatus
Watering schedules are derived from the Plant Grail Knowledge Base, synthesized from thousands of documented care cases and horticultural research on indoor plant water requirements. The calculator adjusts baseline frequencies for five environmental factors: species type, pot size, light exposure, season, and humidity. Overwatering accounts for 34% of all documented plant deaths in our dataset.
