Greenhouse Lighting
Lighting is both crop energy and climate pressure. Solar radiation warms the greenhouse faster than the controller can always reject heat, while grow lights help the east-zone hydroponics rack and shelf crops when DLI is low. Verdify tracks the light story as a loop: outdoor solar, indoor lux, transmission through the structure, accumulated DLI, and grow-light runtime.

Current Light State
These cards are live Grafana panels. If they are unavailable, treat them as the current-light view rather than the proof of the whole lighting story; the seven-day rollups and forecast panels below show whether the room is light-limited or heat-limited.
Light Into The Room
Indoor light is not a simple copy of outdoor light. Polycarbonate diffusion, sun angle, tree shade, greenhouse geometry, and sensor saturation all change what the plants actually see. The indoor LDR is useful for timing and relative changes, but it saturates near bright conditions and is not a calibrated PAR sensor.
DLI And Grow-Light Decisions
DLI is the plant-facing summary: how much usable light accumulated over the day. Grow lights add photons, but they also add electrical load and heat, so their value depends on the crop need, time of day, and the resource-use story.
Seven-Day Rollup
The daily rollup is the planning view: was the greenhouse light-limited, did grow lights fill the gap, and did solar timing line up with greenhouse electrical load?
Forecast Context
Solar forecast is a control input. If the next day is clear, Verdify expects heat load and may need shade, venting, mist, or pre-cooling. If the day is dim, the lighting and hydroponics pages become more important. Solar alignment helps offset grow-light cost, but it does not make lighting free: cloudy forecasts, late-day heat, crop DLI needs, and circuit runtime still matter.
