RAM Ultrasonic Humidifier for Grow Room Humidity Control

Hold your humidity where the plants want it

An ultrasonic humidifier built for indoor growing, adding moisture to the air at up to 400ml per hour from a 5 litre tank. Ultrasonic output means a cool, fine mist with no heating element, so it lifts relative humidity without adding meaningful heat to the room. Output is fully adjustable on a single dial, drawing only 30W on a standard 220-240V supply. Indicator lights confirm power at the socket and show when there is water in the tank and the unit is actively humidifying, so a dry tank is obvious at a glance.

Key Benefits

• Up to 400ml per hour - Enough output to lift humidity in a typical tent or small room.
• 5 litre tank - Long run times between refills, even at higher output settings.
• Fully adjustable - Dial the mist up or down to hit the humidity you are targeting.
• Only 30W - Low running cost and negligible added heat compared with warm-mist units.
• Clear status lights - Show power, water and active humidifying so you know its state instantly.
• Controller ready - Pairs with a humidity controller to switch automatically on and off.

The Trouble with Dry Grow Room Air

Lights and extraction strip moisture out of a grow space faster than most growers expect. When relative humidity falls too low, stomata close, transpiration slows and nutrient uptake stalls with it, so you see slow growth and leaf edges curling even though feed and light are correct. Propagation and early veg suffer most, as young roots cannot draw enough water to keep up. Adding controlled moisture back keeps the plant working.

How to Use

• Fill the tank with clean water and seat it on the base.
• Place the unit off the floor, clear of plants and away from direct fan blast.
• Turn the dial up until your hygrometer reads the humidity you want.
• Plug it into a humidity controller for hands-off automatic switching.
• Empty, rinse and dry the tank regularly to keep the output clean.
