420 Sale | 2026 New Spider Farmer® 32 Pint Dehumidifier – Smart APP Control with RJ12 Cable & Drain Hose, Ideal for Grow Tent & Grow Room

$219.99 Original price was: $219.99.$189.99Current price is: $189.99.
Rated 4.89 out of 5
New Version: SMART HUMIDITY CONTROL The dehumidifier connects to the GGS Power Strip AC5/AC10 and GGS Controller via an RJ12 cable, allowing remote control through Bluetooth or the Spider Farmer app. Seamlessly integrate with the Spider Farmer GGS Series for intelligent control of windspeed, runtime, and Auto Humidity Control. Please let the dehumidifier sit for 24 hours before use, as it contains a compressor. Spider Farmer Dehumidifier Manual & Operation Guide

Why Choose Our Compressor Dehumidifier Over Cheaper Options?
You may find dehumidifiers on the market priced at just a few dozen dollars, but most of those use semiconductor technology. Semiconductor dehumidifiers work by cooling air with a thermoelectric effect, but they are far less effective, especially in colder weather. Our dehumidifier uses a high-quality compressor, which comes at a higher cost but delivers far superior performance.

Why a Compressor Dehumidifier?
Semiconductor dehumidifiers simply can’t get the job done—especially in winter, as they struggle to operate efficiently in low temperatures. In contrast, compressor dehumidifiers are widely used in commercial settings for their effectiveness. In fact, our unit removes moisture up to 39 times faster than semiconductor models. That means faster results and lower energy consumption, saving you both time and money on electricity bills.

How Does It Work?
Our dehumidifier pulls in humid air, removes the moisture, and then releases the dry air back into your tent or space. The collected moisture can either be stored in the built-in water tank or drained continuously using the included hose. According to our tests, it may increase the temperature inside your tent by 2-4℉ (around 1-2°℃), a small trade-off for such efficient moisture removal.

User-Centered Design for Tents
We understand our users’ needs, which is why this dehumidifier is specifically designed for tent environments. The dry air outlet pipe is tailored to fit seamlessly with tents, ensuring optimal airflow. It’s perfect for 2×2 ft (60×60 cm), 2×4 ft (60×120 cm), 2.3×4.6 ft (70×140 cm), 3×3 ft (90×90 cm), 4×4 ft (120×120 cm), and 5×5 ft (150×150 cm) tents. Whether you’re using a small or large tent, our dehumidifier adapts effortlessly to create the ideal environment.

User-Friendly Features
For added convenience, our dehumidifier comes with a power outage memory function. If the power goes out, it will remember its previous settings, ensuring a smooth restart. The dehumidifier retains these settings and will automatically turn back on when power is restored—no manual restart needed.

Why use 730nm IR supplemental light bar? Stem Boost, Flower Induction, Light-induced Sleep

Why use 365nm UV supplemental light bar? Enhance yield, improve nutrients, elevate taste/aroma, sterilize grow area (eliminating mold), aid pest control.

Recommended Grow Light Models: 35.4'' Grow Light Bars Set is Suitable for above 500W light as a reference.
