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
Many plant owners guess at their care routines, leading to root rot, burned leaves, or stunted growth. Generic advice doesn't factor in specific plant species and local climate.
When to Use This Tool
Use this calculator when you bring home a new plant, when seasons change, or if your plant is showing signs of distress.
Who is this for?
- Beginner houseplant owners looking to avoid common mistakes
- Advanced collectors wanting to optimize growth rates
Using this calculator removes the guesswork from your Rose care routine.
What this means for Rose
Proper lighting is the most critical factor for Rose. Too little light leads to etiolation (stretching), while direct harsh rays can scorch the leaves.
How to Use
- Input your window's environmental conditions.
- Get a personalized light estimate.
- Compare it to your Rose's needs.
