Visible baseline values
These baseline ratios and decision rules are included directly in the page so visitors can review core guidance before using the interactive calculator.
| Scenario | Baseline Rule | Safety Note |
|---|---|---|
| Bright indirect | Score around 60-79 usually maps to bright indirect light. | Confirm final placement with a lux meter app. |
| Full sun / very bright | Score 80+ usually maps to full sun or very bright exposure. | West and afternoon exposure can scorch thin leaves. |
| Low light | Score below about 35 maps to low light. | Choose tolerant plants or add grow light support. |
Methodology: Formula pattern: light_score = direction_base + sun_hours_bonus - distance_penalty - obstruction_penalty, then clamp to a fixed 0-100 scale. Plant suitability and placement advice are derived from the resulting light band.
The Problem
