The lighting system includes both white grow LEDs and RGB accent LEDs. OpenShrooly uses lux measurements for easier following of mushroom growing guides!
Dashboard Card

The lighting card shows:
- Current lux (or OFF when lights are off)
- Light schedule below (e.g., “08:00 - 21:00”)
- Icon changes between 💡 (lights on) and 🌙 (lights off)
Lighting Settings
Click the Lighting card on the dashboard to open the lighting schedule modal.

Visual Timeline Scheduler
The lighting control features a 24-hour timeline slider with draggable sun and moon icons:
- Sun icon (☀️): Drag to set sunrise time (when lights turn on)
- Moon icon (🌙): Drag to set sunset time (when lights turn off)
- Yellow highlighted zone: Shows when lights are ON during the day
White LED Intensity
White Intensity slider: Set brightness in lux (0-4000).
This slider uses a logarithmic scale because you are much likely to need the lower numbers.
Recommended Lux Ranges
General Guidelines:
- Most mushrooms: 150-400 lux
- Default starting point: 150 lux
Species-Specific:
- Shiitake: 50-150 lux at pinning
- Lion’s Mane: 100-250 lux at pinning
- Oyster: 200-400 lux at pinning
- Pioppino: 100-300 lux
RGB Color Controls
RGB Color Picker: Use the color picker for accent lighting.
The color picker controls three independent RGB LEDs (0-100% each):
- Red intensity: 0-100%
- Green intensity: 0-100%
- Blue intensity: 0-100%
Blue light tip: Blue light (around 20% intensity) may promote better mushroom development and more compact fruiting bodies.
Light Requirements for Mushrooms
Why Mushrooms Need Light
Unlike plants, mushrooms don’t photosynthesize, but light serves important functions:
- Triggers fruiting: Signals when to produce mushrooms
- Directs growth: Mushrooms grow toward light sources
- Affects morphology: Influences cap color, size, and shape
Photoperiod (Day Length)
Most mushrooms need consistent daily light cycles:
- Typical duration: 8-12 hours per day
- Consistency matters: Keep schedule regular
- Complete darkness: Can cause deformed growth
Light Spectrum
- Blue spectrum (400-500nm): Encourages fruiting and compact growth
- White light: Provides balanced spectrum
- RGB options: For experimentation or aesthetic purposes
Scheduling Tips
Basic Schedule
Set sunrise in the morning (e.g., 08:00) and let lights run for 10-12 hours.
Timezone
Make sure your timezone is set correctly in Settings for accurate scheduling.
