Description
The RAM 12L Dehumidifier is designed to effectively manage humidity levels in indoor spaces, removing up to 12 litres of moisture per day. This makes it an ideal solution for grow rooms where controlling humidity is crucial for preventing mould, mildew, and other moisture-related issues that can harm plants.
Features and Benefits for Grow Rooms:
-
Efficient Dehumidification: Capable of extracting up to 12 litres of moisture daily, it helps maintain optimal humidity levels, ensuring a healthier environment for your plants.
-
Constant or Targeted Humidity Control: You can set the unit to dehumidify continuously for maximum drying or select a target relative humidity level, which the unit will work to maintain. This is particularly useful for maintaining precise humidity conditions during different stages of plant growth.
-
Timed Operation: The dehumidifier features a timer that can be set to switch the unit on or off after a specified period, up to 12 hours. This flexibility allows you to control humidity based on your grow room’s schedule, saving energy and enhancing efficiency.
-
Quiet Mode for Discreet Operation: For situations where quiet operation is needed—such as during nighttime cycles—the dehumidifier can be set to Quiet Mode. This mode reduces fan noise and dims the display, making it unobtrusive.
-
Child-Lock Feature: This function locks the controls, preventing accidental changes to the settings, which is particularly helpful if your grow room is in a shared or accessible space.
-
Flexible Condensate Management: Condensate can be drained continuously into an external drain, reducing maintenance, or collected in the built-in 2-litre tank. An alarm will sound, and the unit will shut down when the tank is full, preventing overflow.
-
User-Friendly Controls: The dehumidifier is easy to operate with an electronic display, allowing you to quickly adjust settings to meet the needs of your grow room.
-
Environmentally Friendly Refrigerant: The unit uses R290 refrigerant, which is more eco-friendly compared to traditional options, aligning with sustainable growing practices.
Key Advantages:
- Maintains ideal humidity levels to enhance plant health and prevent mould growth.
- Adjustable settings to meet specific grow room requirements.
- High water extraction rate of up to 12 litres per day.
- Optional continuous drainage reduces manual emptying needs.
- Quiet operation options make it suitable for discreet environments.
- Easy-to-use electronic controls with safety features like Child-Lock.
This dehumidifier is a valuable addition to any grow room setup, offering reliable performance to help you maintain the perfect growing conditions for your plants.

How to use
Choose continuous running to dry the room quickly, or set a target humidity and the unit will hold it. Change the target as the plants move through each stage: the VPD chart shows what to aim for.
Run a hose to a drain for continuous drainage, or empty the 2 litre tank when the alarm sounds. Quiet mode lowers the fan noise and dims the display, and the child lock stops the settings being changed. For a larger room see the RAM 20L dehumidifier.
Questions
Do I have to empty it?
Not if you set up continuous drainage to an external drain. Otherwise the 2 litre tank needs emptying; an alarm sounds and the unit stops when it is full.
Can I set the humidity?
Yes. Set a target humidity and it works to keep it, or run it continuously for maximum drying.
How long can the timer be set for?
Up to 12 hours, to switch the unit on or off.
