What space is the VDL 12 L/day dehumidifier designed for?

For a 1.2 × 1.2 m tent or a room of 8 to 15 m². It's the step up where a small grow stops needing workarounds and gets real humidity control, since it includes an adjustable hygrostat and continuous drainage. Below that size you'd have more equipment than you need, and above it you should move up in capacity.

Why do you give two capacity figures?

Because conditions matter just as much as the number: it's 12 L/day at 30°C and 80% RH, and up to 16 L/day at 35°C and 90% RH. VDL and Cyclone measure at 30°C / 80% RH, favorable conditions, while Quest uses the American AHAM standard at 26.7°C / 60% RH, which is considerably harsher. When comparing models, always compare both the figure and the conditions.

What advantage does the R290 refrigerant offer?

It works with 40 g of R290 (propane), which has a very low global warming potential. It's the most eco-friendly refrigerant used in dehumidifiers in this range, well ahead of the R410A used in older compressor units. If environmental impact matters to you, this is the cleanest model in the lineup.

Should I use the tank or the drain?

The removable 1.5 L tank works fine for occasional use, but in a grow it fills up fast. For unattended operation, connect the continuous drain to a drain outlet or a container and forget about it. That's the setup we recommend if the unit is going to be running daily.

What extra features does it include?

Humidity adjustment from 30 to 80% RH, a laundry-drying mode, a washable filter, a child lock, and memory of settings after a power cut. That memory function is key: if the power goes out, the unit restarts with the setting you had, instead of switching off. Its noise level is 45 dB and it measures 34 × 22 × 49.5 cm.

Can I use it for drying?

It can support a small drying setup thanks to its 30 to 80% RH adjustment and continuous drainage, which is exactly what's needed to hold 55-62% RH for 10 to 15 days. That said, keep in mind that at low drying temperatures, 18 to 20°C, any compressor unit's performance drops compared to the catalog figure measured at 30°C.

How to use

1. Place the unit in the center of the space, leaving 20 cm of clearance around the vents.
2. Choose the drainage mode: the 1.5 L tank for occasional use, or connect the continuous drainage hose to a drain or container for unattended operation.
3. Turn it on and set the target humidity within the 30–80% RH range, depending on the growth stage.
4. Activate the child lock if there are children around or if you want to prevent accidental changes to the setpoint.
5. Clean the washable filter every 2–4 weeks: a dirty filter reduces airflow and performance.
6. If the power goes out, the unit automatically restores the setpoint thanks to its memory function; however, still check that it has restarted.
