Pre-owned Spider Farmer Genius Grow System SensorPro Kits with CO2 Sensor and PAR Meter, Ideal for Optimizing Grow Tents, Grow Rooms
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
Designed for GGS Systems
Easily replaces the temperature and humidity light(day/night) sensor in GGS Controller Kits and AC5/AC10 Power Strip Kits for seamless integration and reliable performance.
Compatible Only with GGS Devices
Not compatible with controllers or accessories from other brands. Use exclusively with GGS systems for the best results.

Many affordable dehumidifiers on the market use semiconductor technology, which cools air via a thermoelectric effect but performs poorly, especially in cold weather. Our dehumidifier features a high-quality compressor, offering far superior performance for reliable, effective moisture removal. Why a Compressor Dehumidifier?
Semiconductor models struggle to operate efficiently in low temperatures, making them unsuitable for year-round use. Compressor dehumidifiers, widely trusted in commercial settings, remove moisture up to 39 times faster. This means quicker results and lower energy bills—saving you both time and money. How Does It Work?
Our unit pulls in humid air, extracts moisture, then releases dry air back into your grow space. The collected water is stored in a built-in tank or can be drained continuously via the included hose. While it may raise your tent’s temperature by 1-2°C, this is a small trade-off for highly efficient humidity control. User-Centered Design for Tents
Tailored specifically for tent use, the dry air outlet pipe fits seamlessly with tents sized from 2×2 ft (60×60 cm) up to 5×5 ft (150×150 cm). Whether your tent is small or large, this dehumidifier adapts easily to maintain the perfect growing environment. User-Friendly Features
For convenience, the unit includes a power outage memory function, automatically restoring previous settings after power returns. It can also be connected to your own timer for even easier operation.
