RAM 12L Dehumidifier Grow Room Humidity Control

Pull Up to 12 Litres a Day Out of Your Grow Room Air

The RAM 12L Dehumidifier dries indoor environments at up to 12 litres per day, either running constantly to dry a space out or holding a target relative humidity from 30% to 80%. Set your humidity and fan speed and it only kicks in when RH climbs above target. Condensate collects in the 2 litre tank, which alarms and shuts the unit down when full, or fit a hose for continuous drainage. It uses environmentally friendly R290 refrigerant and runs from a clear electronic display.

Key Benefits

• Removes up to 12L per day - enough to hold a tent or small room steady in late flower.
• Target humidity 30% to 80% - it only runs when RH rises above your setting.
• Prevents damp and mildew - keeps moisture out of dense flowers.
• Continuous drainage option - hose it to a drain and skip emptying the tank.
• Quiet mode - dims the display and drops to the quietest fan speed.
• Child-lock and auto shut-off - tamper-proof, and it stops when the 2L tank is full.

Struggling With Humidity Spikes in Late Flower?

High humidity is where a good grow goes wrong fastest. Once RH sits too high the plant stops transpiring properly, meaning poor nutrient uptake and slow growth, and inside dense flowers the still, damp air is exactly what bud rot and mildew need. Poor airflow makes it worse, and a lights-off temperature drop can push a room to saturation overnight.

How to Use

• Position: stand it level with clear space around the inlet and outlet.
• Set the target: dial in a relative humidity between 30% and 80%.
• Continuous drying: to dry a space out, set it to run constantly instead.
• Fan speed: select the dehumidifying level to match the room.
• Drainage: empty the 2 litre tank when the alarm sounds, or fit a hose for continuous drainage.
• Timer: set it to switch on or off after up to 12 hours.
• Overnight: use quiet mode and engage the child-lock.
