Small In Size. Massive In Effect.
It’s the second smallest in Aqualine’s five-strong line-up of humidifiers, but don’t let that fool you - it’s still an absolute workhorse. With a 4.5-litre tank, this machine quietly churns out up to 280ml of mist per hour, covering an area of 1.2m x 1.2m x 2m and running for a blissful 16 hours on a single fill. That’s practically spa conditions - for your plants.
Stronger Stems. Greener Foliage. Better Yields.
Young plants don’t just drink from the soil - they breathe it in through their leaves. Dry air equals stunted growth, yellow leaves, and the kind of limp disappointment usually reserved for supermarket basil. But switch on the Aqualine 4.5L Humidifier, and suddenly everything starts thriving. Stronger stems, greener foliage, better yields. It’s not magic - it’s moisture.
You’ve got a 0–100% output dial, giving you total command over how tropical things get. And a 360° rotating nozzle lets you send that mist exactly where it’s needed - right at your fragile, thirsty seedlings. Not at the wall. Or your leg.
Whisper-Quiet Operation.
It’s also quiet. Almost suspiciously so. No gurgling, no humming - just stealthy, efficient misting. And if it runs out of water? No drama. The Aqualine 4.5L Humidifier just shuts itself off like a well-trained butler. Safety, style, and simplicity.
Weighing just 1.3kg, it’s easy to lift, move, and stash away when not in use. Perfect for grow tents, greenhouses, hydroponics setups, or anywhere you want lush, healthy plants without the rainforest-level noise.
So if your grow space covers 20 to 40 square metres and you’re tired of watching your plants wither like Victorian poets, do yourself a favour - get the Aqualine 4.5L Humidifier. The Midi Mist doesn’t just humidify the air. It transforms it.
