GrowPAR

GrowPAR turns your iPhone into a professional-grade PAR light meter for indoor growing, hydroponics, and plant research.

What is PAR?
Photosynthetically Active Radiation (PAR) measures the light your plants actually use for photosynthesis — between 400–700nm. Unlike lux meters, GrowPAR measures what matters most to your plants.

KEY MEASUREMENTS
- PPFD (μmol/m²/s) — Instant photon flux density
- DLI (mol/m²/day) — Daily Light Integral for growth optimization
- CCT (Kelvin) — Color temperature of your light source
- Lux — Illuminance measurement

PLANT INTELLIGENCE
GrowPAR includes a database of 36+ plants with scientifically accurate targets:
- Stage-based PPFD targets: Seedling → Vegetative → Flowering → Harvest
- Ideal temperature (day/night), humidity, and CO₂ levels
- Hydroponics parameters: pH range and EC values
- LED distance and photoperiod recommendations
- Real-time sufficiency indicator: Is your light enough?

LIGHT SOURCES
Calibrated for all grow light types:
- Full Spectrum LED • Red/Blue LED • HPS • CMH • Natural Sunlight

MEASUREMENTS & HISTORY
- Save unlimited measurements with timestamp
- Filter by plant and light source
- Export to CSV for analysis

CALIBRATION
Use with Apogee MQ-500 or similar quantum sensor for research-grade accuracy.
