Spider Farmer 32-Pint Dehumidifier (2025) – Smart Control with RJ12 & Drain Hose

The Spider Farmer 32-Pint Dehumidifier (2025) is the next generation of controlled humidity in grow tents and grow rooms . Thanks to app control , RJ12 Smart Control (seamless with the Spider Farmer GGS series ), and continuous drainage via the included hose, it keeps your climate precisely within target range – from rooting to drying.

Why compressor instead of semiconductor?

• Dehumidification up to 39x faster than semiconductor-based devices – for rapid results and greater efficiency.
• Reliable performance even in cooler temperatures .
• Energy efficient with larger air volume – saves time and electricity costs.

Smart features for growers

• Spider Farmer App : Control & monitoring even remotely.
• RJ12 connection to the GGS series : intelligent control of air speed & running time, simulates natural conditions.
• Water tank full alarm : Stops automatically, displays a message on the device and in the app; restarts after emptying.
• Drying mode (low-speed) : Gentle drying at 45–55% RH for flavor, potency and quality.
• Drain hose included for continuous drainage – ideal for longer use.

Size selection & practical example

The required dehumidification capacity depends on your plants ' water consumption . Example: 6 plants in a 4×4 tent , 1 gallon (≈ 8 pints) every 2 days:

1. Total per pour: 6 × 1 gallon = 6 gallons = 48 pints
2. Daily requirement: 48 pints / 2 days = 24 pints/day
3. Adaptation to climate: cool/dry (−15%) ≈ 20.4 pints/day , warm/humid (+15%) ≈ 27.6 pints/day

This 32-pint dehumidifier comfortably covers typical 4x4 setups. If you also use an air conditioner , subtract its dehumidification capacity from the required capacity.

VPD & humidity conductivity

For precise control, adequate ventilation (fans) and integration via the GGS power strip are recommended. Note: When connecting the dehumidifier to the GGS, deactivate the device's internal sensor to ensure optimal interaction between all components.

Optimized for tents

The outlet and airflow are designed for grow tents ; ideal for 60×60 , 60×120 , 70×140 , 90×90 , 120×120 , and 150×150 cm , for example.
