Aqualine Dehumidifiers - Compact Moisture Control for Grow Rooms
Best for: Growers who need to pull excess humidity out of a tent or grow room to stop mould, mildew and slow drying without buying commercial-scale kit.
Our thoughts
Humidity creeps up on you, especially late in flower when the canopy is transpiring hard, and a dehumidifier is the one bit of kit that quietly stops that turning into a mould problem. The Aqualine range covers 12L, 20L and 40L a day extraction, so you can match it to your room without paying for capacity you don't need. Nothing fancy, just steady, predictable moisture removal.
Aqualine Dehumidifiers use standard refrigerant-based dehumidification: air is drawn across a cold coil, moisture condenses out and drips into a collection tank, and the drier air is pushed back into the room. The range covers 12, 20 and 40 litres of extraction per day, with the 40L model rated for rooms of roughly 30-40m² and specced with a 4-litre internal water tank, electronic controls, a 0-24 hour timer and a noise level under 53dB.
All three sizes are built with castors on the base for easy repositioning between rooms, which matters if you're running more than one tent and want to move the unit around rather than buying one per room.
How it compares
Aqualine sits at the accessible end of grow-room dehumidification, well below commercial units.
- Quest dehumidifiers are the recognised benchmark for licensed commercial facilities, engineered for 24/7 operation at high heat and humidity loads, but they're priced and sized for that scale, not a home tent or small room.
- Standard household dehumidifiers (the kind sold for damp problems in a house) aren't built to cope with the heat and constant humidity swings a grow light and transpiring canopy create, and tend to wear out faster in that environment.
- Aqualine's range gives you a proper grow-specific unit sized to home and small commercial rooms without stepping up to Quest-level pricing.
You get purpose-built grow-room dehumidification sized correctly for a tent or small room, at a fraction of commercial pricing.
Usage guidance
Getting the size and placement right makes the biggest difference to performance.
Sizing to your room
Match litres-per-day extraction to room size and canopy - the 40L model is built for roughly 30-40m², so a single tent will usually be well served by the 12L or 20L model.
Placement
Stand the unit on a level surface with clear airflow on the intake and exhaust sides, and keep it away from direct contact with wet media or standing water.
Draining
Empty the internal tank regularly, or plumb in a continuous drain line if your model supports one, so the unit doesn't cut out when the tank fills.

Who this is for
- Tent growers dealing with high humidity late in flower
- Anyone drying or curing in a space that needs moisture control
- Growers with more than one room who want a mobile unit rather than fixed extraction
- Budget-conscious growers who don't need commercial-scale Quest capacity
Best suited to single-tent or small multi-room setups rather than large commercial facilities.
Our take
Reliable, sensibly priced moisture control that does the job without the commercial price tag - if your room is running damp, this is the straightforward fix.
Does exactly what it should, day in, day out. Size it to your room and it'll keep humidity where it needs to be.
