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.

Optimize Your Irrigation Plan: Pair with the Spider Farmer GGS AC5 Power Strip Kit or GGS AC10 Power Strip Kit drip irrigation system to greatly enhance your growing efficiency and experience. 

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

Note: Before using the 4-in-1 sensor, please remove the cover with the “Spider Farmer” logo to expose the white PPFD sensing area for more precise data monitoring.

Best Soil Sensors for Beginner Gardeners

Soil Sensor Features​

The GGS soil sensor measures the temperature, WC (water content), and EC (electrical conductivity) of the soil, providing you with accurate data about your soil's condition to help optimize the growing environment for your plants.

Optimize Your Irrigation Plan

Pair with the Spider Farmer GGS AC5 Power Strip Kit or GGS AC10 Power Strip Kit drip irrigation system to greatly enhance your growing efficiency and experience. The system allows you to set target soil moisture levels or customize irrigation cycles for fully automated watering.

Watering Triggers and Settings

a. Watering Trigger Settings

Based on the humidity measured by the sensor, you can set a watering trigger value. It’s recommended that during the first watering, you wait until you see water flowing out of the bottom of the planting bag, then record the humidity at that point. Generally, the watering trigger value should be set between 60%-80% of that humidity level. You can also adjust this value based on your experience to find the ideal humidity level to trigger watering.

b. Recommended Accessories

For better automation, you can pair the GGS soil sensor with the GGS Power Strip and hydroponic drip irrigation system. By setting up a drip irrigation schedule, the system will automatically activate watering based on the set humidity threshold. When the humidity reaches the set value, the system will decide whether watering is needed, ensuring your plants get the right amount of water.

Pro Version vs. Non-Pro Version

a. Non-Pro Version

Supports connection to only one sensor and does not allow soil type selection, making it ideal for small-scale use.

b. Pro Version

Supports up to 6 sensors and will enable you to choose different soil types. Once a soil type is selected, the system uses models for different substrates to further optimize humidity readings. This version is perfect for users who need to monitor larger areas and require more precise data.

Smart Control Via GGS System

Smart control via Spider Farmer App — compatible with GGS Controller, GGS AC5 Power Strip Kit, and GGS AC10 Power Strip Kit.

How to Use?

Insert the probe horizontally into the soil to obtain accurate readings. It is recommended to insert the probe into the planting bag at about 1/3 of its height above the ground, closer to the root zone.

Why Do You Need the Glow30 Side Lighting?

Most grow lights are mounted on top of grow tents, but light struggles to penetrate deep into the lower canopy. This means lower buds and branches receive less light, resulting in slower growth, smaller yields, and lower potency compared to the top. Without proper lighting,you’re not maximizing your plant’s full potential. Spider Farmer Glow30 solves this problem(Side lighting, under lighting, supplemental lighting)! It provides targeted side lighting, ensuring that lower buds receive the extra light they need to grow bigger, denser, and healthier. The flexible installation lets you mount it on grow tent sidewalls or place it anywhere for optimized light distribution. Plus, it’s super energy-efficient—just 32W! Even if you run it 4 hours per day for 21 days, your electricity cost will only be a few dollars. With better light coverage and bigger yields,Glow30 is the upgrade your grow setup needs.
  • Four 13″LED bars designed for inter-canopy or supplemental lighting to boost plant yields.
  • Provides expanded light coverage to areas your primary grow lights have trouble reaching.
  • 360° rotating spacers on the clips allow you to adjust the light direction.
Length of wires at both ends of a single light bar: 70cm/25.56'' Single Bar Size: 13.54'' x 1.77'' x 1.46''/34.4 x 4.5 x 3.7cm Package contents: 4x Light Bars ( 32 watt/4 Bars) 4x Fixing Clips 1x Backed Adhesive Velcro 4x Bondage Strap 5x Plastic Tie
