Ram Humidifier 13L – High Capacity Ultrasonic Mist 1100ml/h

The Ram Humidifier 13L is the heavy artillery your grow room needs to maintain stable VPD (Vapor Pressure Deficit) without you having to live inside the tent. It is a high-capacity ultrasonic device capable of pumping out 1100ml of mist per hour, ensuring your plants never suffer from dry stress again, while its massive tank gives you the autonomy you've been looking for.

Why is humidity control a nightmare for growers?

Let's be real: is there anything more annoying than checking your grow tents 120X120 and finding the humidity has dropped to 30% because your small humidifier ran dry hours ago? You spend your day running back and forth with water jugs, stressing over crispy leaves and slowed growth, feeling like a slave to your equipment rather than a gardener.

If you keep relying on low-capacity gadgets, you are essentially gambling with your harvest. Inconsistent humidity stunts vegetative growth, invites pests like spider mites, and prevents your plants from reaching their full genetic potential. It's frustrating to put in so much effort only to have dry air ruin your progress.

The Ram Humidifier 13L changes the script entirely. With its massive capacity and high output, you fill it once and let it do the heavy lifting. It floods your space with the perfect amount of moisture, allowing you to relax while your plants enjoy a tropical paradise.

What exactly does the Ram Humidifier 13L deliver?

This isn't a toy; it's a tool designed for serious cultivation. It comes ready to plug and play, offering robust performance for medium to large spaces.

• 13-Liter Tank: A huge reservoir that minimizes maintenance frequency.
• Adjustable Output: An analog dial allows you to control the mist intensity up to 1100ml/h.
• Ultrasonic Technology: Creates a fine mist without generating heat or noise (<35dB).
• Directional Nozzle: Lets you point the mist exactly where it's needed.
• Auto-Shutoff: Protects the unit when the water runs out.

How your routine changes from now on

Imagine walking into your grow room and seeing your plants praying to the light, lush and green, because the environment is perfectly stable. Instead of refilling a tank three times a day, you might only need to check the Ram Humidifier once every day or two, depending on your settings. That is freedom.

Because it uses ultrasonic technology, it's whisper-quiet. You won't have that annoying hum vibrating through the floor. Plus, since it's analog, it pairs perfectly with an external timer or controller, giving you total automation over your Climate Control.

Advantages and benefits you’ll notice from day one

• Massive Time Saver: The 13L capacity means fewer trips to the tap and more time enjoying your hobby.
• Explosive Veg Growth: Consistent high humidity speeds up cell division and leaf development.
• Total Silence: At less than 35dB, it's stealthy enough for bedroom grows.
• Cool Mist: It doesn't raise the temperature of your grow space, unlike steam humidifiers.
• Simple Operation: No complex digital menus to break; just a reliable dial for instant adjustment.
• Versatility: Powerful enough for large rooms but adjustable for smaller tents.

Tips to combine it with other Pevgrow products

To get the absolute most out of this beast, you shouldn't just guess the humidity levels. Precision is key in this game.

• Pair with a Controller: Since the Ram 13L has an analog switch, you can plug it into a humidity controller. The controller cuts the power when the target RH is reached and turns it back on when it drops.
• Monitor with Accuracy: Always have a reliable thermo-hygrometer at canopy level to verify the mist is distributing evenly.
• Water Quality: Use osmosis water or distilled water to prevent calcium dust from clogging your carbon filters.

Frequently Asked Questions

How long does a full tank last?

At maximum power (1100ml/h), the 13L tank will last approximately 12 hours. However, you rarely need to run it at 100% constantly, so at medium settings, it can easily run for 24 hours or more.

Can I use tap water?

You can, but we highly recommend using distilled or RO (Reverse Osmosis) water. Tap water contains minerals that can create a white dust residue on your equipment and clog the ultrasonic membrane over time.

Is it suitable for a small 60x60 tent?

It might be overkill for a very small tent unless you run it on the lowest setting. It is ideal for 1.2m x 1.2m tents or larger rooms. For smaller spaces, check our other Grow tent humidifier options.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I upgraded to the Ram 13L for my mother plant room. Before that, I was using two smaller 6-liter units, and one always seemed to run dry right when I was away for the weekend. The stress was real.

Switching to this unit was a game-changer. I filled it up, set it to about 60% power, and didn't have to touch it for nearly two days. The mist output is seriously impressive—it looks like a fog machine at a concert. My tip: Don't place it directly under your extraction fan, or you'll suck all that good moisture right out. Place it near an oscillating fan to spread the mist evenly across the canopy.
