Bloomroom Ultrasonic Humidifiers
With a 4.5 litre capacity, this unit has a dial to vary the output and will turn off if the water runs out.

This humidifiers uses ultrasonic humidification to release water particles back into the air to increase the water moisture levels in the room. This size humidifer is ideal for tents or smaller growing areas.

Humidity is a vital part of creating the perfect enviroment for vigorous plant growth that leads to high yields.

When lights are on aim for 70% relative humidity during the growth stage, tapering off to 50% at the end of flower.

Low humidity levels are likely to cause early yellowing and slow down plant growth, leading to disapointment!

There is no need to run the humidifier during lights off, simply plug in to a segmental timer and set the humidifier to come on just after the lights and turn  off just before lights out.
