Real-Time Soil Data: The 3-in-1 Soil Sensor Pro monitors soil moisture (volumetric water content, VWC), temperature, and electrical conductivity (EC), providing crucial data for plant growth.

Multiple Connections：3-in-1 Soil Sensor Pro supports multiple connections — one GGS system can connect up to six Soil Sensor Pros.

CO₂ Sensor for Enhanced Growth Efficiency
Studies show that CO₂ supplementation can increase plant growth rates by 20-100% and boost crop yields by 20-30%. Combined with high PPFD lighting, CO₂ further enhances photosynthesis, leading to faster, healthier plant development.

PPFD & DLI Monitoring for Perfect Light Placement
New to growing and not sure how high to hang your lights? The Sensor Pro kit includes a 4-in-1 sensor that tracks temperature, humidity, VPD, DLI, and PPFD to help you find the right light placement and shows you real-time PPFD levels and the corresponding DLI reference values. It also supports PPFD dimming—just set your target PPFD, and the lights will automatically adjust brightness to deliver the ideal lighting for plant growth:

Seedling Stage: 100-300
Vegetative Stage: 400-600
Flowering Stage: 800-1000
