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. 11 LANGUAGES English · German · Spanish · Turkish · French · Italian · Portuguese · Russian · Japanese · Chinese · Arabic Whether you're growing tomatoes, microgreens, or orchids — GrowPAR gives you the data to grow smarter.

Verdict
The clearest difference is ads: GrowPAR at none against GrowCentral's shown. GrowPAR also leads on update cadence (every 4 days vs every 6 weeks). GrowCentral's advantage is iOS requirement (14.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
