The Unsung Grow Room Hero.
Let’s be clear: moisture is the enemy. Not in your tea, or in the atmosphere on a warm summer’s day, but in your grow room - where it clings to leaves, drips from surfaces, and quietly invites the worst kind of biological party crashers. Fortunately, the solution now comes in a compact, British-engineered box called the Aqualine 20 Litre Dehumidifier. And unlike many middle-tier devices, this one doesn’t pull its punches.
Built by the horticultural brains at Aqualine - a UK-based brand that actually understands what growers need - this 20-litre model is the mid-sized marvel in their trio of environmental control solutions. Whether you’re working in a dedicated 20m² grow tent or a spare room, the Aqualine Dehumidifier is the kind of hardware that keeps your grow clean, stable, and performing at its absolute best.
Function Over Faff.
A lot of growers underestimate the havoc that high humidity can cause. Sure, plants like a bit of moisture - but once you tip over into the 70%+ range, your growing space becomes a playground for mould, mildew and other nasties that can wipe out weeks of hard work.
The Aqualine 20 Litre Dehumidifier steps in with surgical precision. It doesn’t just crank the fan and hope for the best. Instead, it actively measures and maintains your target relative humidity, adjusting airflow and activity to hit that sweet spot where plants thrive, but pathogens perish.
Want it simple? Run it 24/7 in continuous mode. Want more control? Set your preferred RH, plug it into a timer, or use the 24-hour scheduling to manage it around your lighting cycle. For overnight use, there’s even a Quiet Mode - where the unit dims its lights and slows the fan for whisper-quiet operation under 47dB. It's super compact too measuring in at a slim 60 x 37 x 8cm. Ideal when you're trying to keep things discreet.
Plug In. Switch On. Go.
No need for plumbing qualifications or three hands. Unbox it, plug it in, choose your settings, and you're off. If you're collecting water, the internal 3.7L tank is more than enough for moderate conditions, and when it fills, the machine shuts off automatically with a friendly beep to let you know.
Prefer continuous drainage? Just run a hose from the unit to a nearby drain and never think about emptying again.
Mobility is also covered. With integrated handles and four free-rolling casters, the Aqualine Dehumidifier glides from room to room like it owns the place - because frankly, it should.
Designed For Grow Tents.
The Aqualine Dehumidifier isn’t some rebadged home appliance. This is purpose-built for indoor gardening. It’s compact enough to fit neatly into tight grow spaces, but powerful enough to regulate the environment in rooms up to 40 square metres. And with sturdy caster wheels, it’s mobile - because sometimes you do want to move it without dragging your setup apart.
It’s the largest model in Aqualine’s professional-grade lineup, making it the top-tier option for those managing full-room environments, flowering stages, or high transpiration crops.
Enhance Flavours. Eliminate Mould & Rot.
The Aqualine Dehumidifier is the piece of kit you didn’t know you absolutely needed. It doesn’t just stop mildew - it prevents it from ever happening. It stabilises your environment, boosts plant health, and lets your lighting, feeding, and airflow actually do their job.
If you’re serious about growing - herbs, flowers, veggies, whatever - and you’re sick of sticky, soggy, frustrating conditions, this is your answer.
Aqualine Litre Dehumidifier - it doesn’t just dry the air. It rescues your grow.
