3D Light Map and Equipment Placement
GrowScope builds a physically modeled 3D map of light distribution across a grow space, using a Lambertian light-source model and material-specific wall/ceiling/floor reflectance, calibrated against your own PPFD readings rather than a fixture's spec sheet.
How to do this in GrowScope
- Open the box/place setup and enter its width, depth, and height, plus the canopy height.
- Choose the wall material (mylar, white, tracing paper, black, or glass) — each has a fixed, documented reflectance value used by the model.
- Add each light fixture with its power (W), mounting height, and beam-angle type (quantum board, bar/linear, COB with reflector, or custom).
- Open the Light map (3D indoors, or the 2D top-down view for a balcony) to see the modeled distribution.
- Optionally tap points on the map to add real PPFD calibration measurements — the more calibration points, the more the map reflects your actual space rather than pure calculation.
3D Light Map
- Category
- Lighting
- Purpose
- Model light distribution across the grow space and calibrate it against real PPFD readings.
- Input
- Box dimensions, canopy height, wall material, per-fixture power/height/beam type, optional PPFD calibration points
- Unit
- cm (dimensions), µmol/m²/s (calibration)
- Location
- Light section → box/equipment setup, then the Light / Ventilation / Measurements map tabs
- User action
- Enter box dimensions and wall material
- Add fixture(s) with power and mounting height
- Optionally tap the map to add PPFD calibration points
- Output
- A rendered light field (3D or 2D top-down) with a calibration-status line, plus a light-assessment panel giving a verdict (insufficient / acceptable / good / excessive), dark/hot-zone findings, uniformity, computed DLI, and recommendations.
- Used by
- AI equipment-placement optimizer, CO2 target (via recent PPFD average), DLI targets
AI Equipment Placement Optimizer
- Category
- Lighting
- Purpose
- Suggest fixture and plant position changes to improve light uniformity.
- Input
- None to enter directly — it reads the box/lamp/plant geometry already on file
- Location
- Light section → "AI equipment placement" button on the 3D map
- User action
- Tap the optimizer button
- Review the before/after comparison
- Save or cancel the suggested changes
- Output
- A before/after report (PPFD and uniformity) computed by a local math solver, informed by a separate free-text AI analysis — the AI does not calculate the physics itself. Nothing is applied until you save.
- Used by
- None
- Availability
- Pro / AI-credit-gated
Notes
- The AI's role here is explicitly limited to a free-text analysis and weighting which goals matter most — the actual coordinate math is done by a separate deterministic solver, not the AI model.
Frequently asked questions
Does the 3D map work without any PPFD measurements?
Yes — it starts as a pure calculation from your box geometry and fixture data. Adding real PPFD calibration points makes it more accurate to your actual space.
