Grow Room Humidifiers – 4L, 5L & 15L

Holding the right humidity is one of the easiest ways to keep young plants happy. Our grow room humidifiers come in three sizes, so you can pick one to suit a propagation tent or a full room.

• 4L – 30W, up to 350ml/hr: compact and low-wattage, ideal for small tents and propagation
• 5L – 30W, up to 360ml/hr: a little more capacity, so fewer refills
• 15L – 100W, up to 1500ml/hr: high output for larger tents and grow rooms

Why add a humidifier?

• Helps stop seedlings and cuttings drying out
• Supports steady growth in veg, when plants like higher humidity
• Counters dry air from heaters, extraction and LED setups

Tip: use a hygrometer or controller to keep an eye on humidity, and fill with clean water to reduce mineral residue.
