Sensor Pro Kits

Precision Sensors for Optimal Plant Growth
Designed for growers seeking maximum growth performance, ideal for CO₂ supplementation and high PPFD lighting. Equipped with a Temperature & Humidity PPFD Sensor, which replaces the temperature and humidity light(day/night) sensor in GGS Controller Kits.

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 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, and PPFD to help you find the right light placement and shows you real-time PPFD levels. 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
Note: Before using the 4-in-1 sensor, please move the cover with the “Spider Farmer” logo to expose the white PPFD sensing area for more precise data monitoring.

Compatible Only with GGS Devices
Not compatible with controllers or accessories from other brands. Use exclusively with GGS systems for the best results.
