What is the VIVOSUN AeroDrain D12 used for?
The VIVOSUN AeroDrain D12 is a smart dehumidifier built for grow tents and small indoor grow spaces. It helps prevent mold, stabilize VPD, and reduce humidity spikes during flowering, drying, or lights-off periods. It works well in tents up to 5×5 ft or smaller, but avoid over-drying in compact setups.
How much moisture can it remove, and how does drainage work?
It can remove up to 12L per day under ideal conditions. It includes a 2L tank with auto shut-off and also supports continuous drainage via hose. Continuous drain is best in high humidity or drying stages to avoid overflow interruptions.
Can I duct the VIVOSUN AeroDrain D12 to or from my grow tent?
Yes, the D12 includes 130mm and 150mm duct adapters for flexible setup. You can place it outside the tent and duct air through port holes. Keep duct runs short and smooth for best airflow, and always install the unit on a stable, level surface.
Does it include a sensor probe and VPD control?
Yes. The D12 has a remote sensor for temperature and humidity, enabling real-time VPD tracking. Place the probe near canopy height—not in airflow blasts or dead zones—for the most accurate readings and control.
Can I control the D12 remotely or use it without the app?
Yes to both. The D12 connects via 2.4GHz Wi-Fi and works with the VIVOSUN Smart Grow System and app for remote control and automation. It also works with onboard buttons if you don’t want to use the app.
How does it perform in cold rooms or lower temperatures?
Dehumidification slows down in cooler rooms because cold air holds less moisture. The D12 operates best between 41°F–90°F (5°C–32°C) and may add slight warmth while running. Some fan hum and compressor noise is normal.
What size is the unit, and is it easy to move?
The AeroDrain D12 is compact—about 10.83" × 7.28" × 18.98"—and includes caster wheels and side handles for easy positioning. Be sure to leave space around the inlets and outlets for proper airflow.
Does it have a filter, and how often should I clean it?
Yes, it includes a washable dust filter. Clean it every 2–4 weeks depending on your environment. Reduced airflow or louder operation usually means it's time for cleaning. Also check the tank and drain line occasionally to avoid buildup.
What humidity should I set, and can it run all the time?
Set RH based on your plant stage and temperature (or use VPD mode for smarter targeting). The D12 can run continuously but shouldn’t need to unless your room is very humid. Avoid short cycling by placing the probe properly and avoiding tight setpoints.
Why isn't it pulling much water even when humidity feels high?
Common causes include cold temperatures, a dirty filter, poor airflow, or the probe being in a bad location. Also, if your setpoint is already close to ambient humidity, removal slows down naturally.
Why are humidity readings different from my other hygrometer?
Sensor placement is key. Readings can vary by location—even a few feet apart. For a fair comparison, place your other hygrometer right next to the D12’s probe. Some apps allow sensor calibration offsets if needed.
Is the VIVOSUN AeroDrain D12 safe to leave running overnight?
Yes. It's built for continuous operation. Just ensure it’s level, airflow isn’t blocked, and either the tank is emptied regularly or a continuous drain is set up to avoid overflow.
Can I run the D12 on an extension cord or different voltage?
It’s best to plug directly into a grounded outlet. If you must use an extension cord, use a heavy-duty one rated for high-draw appliances. Check your unit’s label for exact voltage—some regions require 240V, others 120V.
Can the D12 help manage humidity spikes during lights-off?
Yes. The AeroDrain D12 is great for curbing RH spikes that often happen when lights turn off. Use good airflow and correct probe placement for stable results during these transitions.
What’s the most common setup mistake with the D12?
Improper sensor placement—like sticking the probe in a dead corner or direct airflow—leads to bad readings and short-cycling. Always place it near the canopy, away from air blasts, and clean the filter regularly.
