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 1-2°C (around 2-4°F), a small trade-off for such efficient moisture removal.
Ideal for Summer Humidity Control
Summer humidity can be challenging, especially in grow tents where moisture can quickly build up, affecting both your plants' health and the growing conditions. This dehumidifier is designed to handle the increased humidity levels typical of summer, ensuring your environment remains stable and conducive to plant growth. With its ability to regulate humidity, you’ll avoid problems like mold and mildew, which thrive in high-moisture conditions.
User-Centered Design for Grow 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.

Having noted the low overall ratings of other heat mats compared with Spider Farmer, I gave this unit a try. I am using the paper towel method to germinate hot peppers. The controller was set to 82F, and the sensor placed between zip loc bags containing the seeds. Adjacent to the sensor was a hand-calibrated reference thermometer previously used to do quality assurance monitoring in a medical lab. There is a slight delay in the sensor readings, but at the top and bottom of the temperature range the Spider Farmer was off by less than one half of one degree compared to the reference. That is pretty hard to beat for a product in this price range! A second lab thermometer displayed a full degree below the reference. Yes, I am happy and would suggest this product to anyone using seedling heat pads. It also worked with an older heat pad purchased years ago from a seed company.
