Useful direct-light window
5 modeled hours · part-day direct light
This is a geometry-based screening window, not a horticultural guarantee. Building shade, canopy and exact species requirements still matter.
Will it live here?
What actually gets enough light here, at the hours that matter?
Use the place you really have—not the generic 'full sun' label—to narrow what belongs there.
Reads the same property record as every other instrument.

This instrument's own intelligence
What the planting spot actually behaves like
The useful question is not only 'full sun or shade?' It is when direct light arrives, how hard the spot heats, and whether it stays wet or dries fast.
Heat / drying pressure
Heat 66 · wind 44
Two places with the same nominal sun hours can behave very differently if one dries rapidly or reflects heat.
Repeated wetness
Wetness proxy 31
Use this to decide whether drainage and drying deserve investigation before choosing a plant or container.

This is decision support, not engineering.
Structural design, code compliance, drainage engineering, electrical work, HVAC sizing and guaranteed plant or material performance stay outside this instrument. When the answer depends on one of those, the product should stop and tell you what professional fact is missing.
