Size: 4.5L Plant Humidifier
I read all the reviews for the most part and it had be second guessing myself but I purchased it anyway after researching many other units and I decided on this one. It’s being used for a 40 gallon ball python terrarium. It’s works extremely well and way better than I anticipated. Definitely worth the extra $20-$30 over the reptile style ones. The good thing about this is it can be used for several different applications. I’m using it at level 1 or 2 and it’s pumping out a solid amount of vapor. Helping my ball pythons home look and feel like a real ballers pad lol. Ultra quiet, can’t hear anything but some trickles of water every now and again and that’s barely noticeable as well. It keeps the temp a bit lower so I have to adjust my heat lamp to keep it all dialed in correctly. I would definitely buy this again unless it stops working in a couple to a few months then I’ll be pissed lol!

This thing is a trooper, can humidify a large room let alone a small tent. I have a few of these and haven't ran into any issues, they pump out humidity to the point my father-in-law "searched" the brand and asked a few more follow up questions :) The lid is easily opened from the top and filling it is a breeze, unlike screw-on versions you see everywhere else. I figured if this could last in harsher environments, my bedroom wouldn't be an issue and sure enough, it is not. This system is quiet and effective, it is also quiet enough to have running while I sleep, making a Minnesota winter much more bearable as our furnaces suck out every drop of moisture (we were more dry than the Sahara Desert at one point). The two annoyances would be that an external sensor must be used to read the temp/humidity and the light flashes when the tank is low (annoying if you are sleeping). A little planning and a small cardboard flap helps me get around these issues, but I figured I should mention them. Overall, this is a great humidifier for those looking to have a larger water tank that is easy to fill/clean and can be set to a desired humidity range.

The AC Infinity CLOUDFORGE T3 is a game changer for any grow tent. The VPD controls and 10-level precision settings make it incredibly easy to maintain the perfect humidity levels. The 4.5L tank lasts a long time, the targeting hose directs moisture exactly where it's needed, and the no-leak design works flawlessly. Setup was quick, and the build quality is excellent. If you're serious about growing healthy plants, this humidifier is worth every penny. Reliable, easy to use, and highly effective.

I ordered this small version because I saw YTubers who probably had their jumbo size humidifier sponsored, share this in their videos. I wanted a humidifier specifically for plants and to use the VPD function, but nope; there is another part I have to purchase AND no where does it tell you that unless you know specifically to ask for it on the T3 model because this product clearly says VPD. Forget about using the app if you have no controller...... forget it. I wanted a nice humidifier for plants, did all the research and still could not use it because unless I purchase one of the more expensive models which has that function in the machine already, I have to purchase something called a leaf temp offset. What in the world is that, how do I use it, and how much does it cost? I even asked Rufus, and there are two different answers. Rufus said the VPD was incorporated in the humidifier, until I asked what about the T3 model. Guess when I figured out to ask that question? After I got my humidifier and had no idea how to make it work. The system apologized and said, I needed another part because the VPD was not incorporated in this model. I feel bamboozled. There is little to know information on YT, this site and the manual is a joke. Trying to reach the company through Amazon was a bust so I called this morning and was told, oh, it won't work without this part. When I asked why didn't they say that on Amazon, there was no answer. They give the same manual with all the models in it and not much on how to use the functions. I would not have purchased this had I known I'd need a separate part. I don't need a grow tent to use it so that was a plus. Though it puts out good "smoke" you have to fill it up at least one per day. The fill point is so small and narrow you are going to end up spilling water on the floor/carpet, so perhaps sending this back is a blessing in disguise. I wanted to like it but I will buy something simple and cheap and save my frustration for something more appropriate.

Very cool! I have the 2x2x6 tent and this really helps with my vpd management. I noticed how quickly this adjusted my tents humidity. Its easy to set, and just walk away. Pros: 1. Easy setup for different temps and auto shut off for vpd/rh 2. Efficient device, quickly adjust vpd in tent 3. Ultrasonic mist to prevent too much heat 4. Quiet 5. Leakproof with a sleek design 6. Easy to disassemble to clean easily 7. Auto screen off with controller paired (cable included) 8. Clear tank, easy to see water level Cons: 1. The fill access flap is only able to be oriented at the rear of the humidifier. This isnt much of an issue since you can lift the tank off the base to fill. 2. The lid doesnt snap on very easily after being removed. It takes a little wiggling but eventually it goes back on Overall I would consider this a must have. This is way better than just using a standard humidifier to try to manage vpd. The cons are manageable so don't skimp and just get the right equipment the first time around.

TL;DR: Tried several humidifiers for my greenhouse but none worked until I got the 4.5L Cloudforge. It’s powerful, affordable, and maintains high humidity perfectly. Only drawback: the flimsy lid needs a locking mechanism. Overall, I am very impressed! After testing a few wick humidifiers recently, including the 4-gallon Vornado, I was still unable to reach the humidity level I needed for a small greenhouse (100%). Eventually, I decided to try this brand after considering Vivosun, a brand I’ve relied on for quality garden products in the past. Unfortunately, their store only offered a large reservoir humidifier, which was far beyond my needs. I purchased the 4.5L Cloudforge and was very impressed after setting it up. The humidity control options are excellent. It immediately produced a substantial amount of vapor and quickly humidified the greenhouse. I set it to auto-cycle on and off every hour, and it has worked flawlessly. The only downside is the lid that connects to the hose. It’s extremely flimsy and lightweight, and they should have included a locking mechanism to prevent the lid from coming off of the unit if the hose is bumped. If this design flaw was addressed, this would be a five-star product. Overall, it’s a purpose-built, affordable humidifier that works exceptionally well in high-humidity environments. Very impressed for a first-time customer!

My only complaint is that I didn’t get the bigger ones. These are great. I have four of them. I’m going to have to build an auto-fill system for them, though. If your grow space is drier and hotter, or you vent a lot, they can empty themselves quickly.

I am updating my review after using it for a while now and after seeing some of the negative reviews. I have had zero problems with this unit or the 2nd unit I bought for my friends tent. My grow environment is mostly Vivosun so I can't really speak to its functionality with the AC Infinity Hub/App. What I can say is that the built in controls offer plenty of options and its been great. It is actually one of the few things in my tent that I don't worry about anymore. I can set a range and it stays within the parameters I set. You can also set the VPD range as well, all without the external controller and app. The hose attachment works as expected, just keep the open end pointed up or water condensation will drip from the end. So don't have the end of the hose directly above anything you don't want getting wet like a heater or fan. Also, I do not remove the tank to fill it up, instead I fill with gallon jugs of water while the tank is on its base. I am looking into hooking it up to a reservoir system. A very trusted grower named Jeremy, from the Build-a-Soil YT channel, made an excellent video showing how he did it on this exact model. Just look for his video, "humidifier tips/side by side grow using AC Infinity grow tents episode 03." It looks very simple to set up and does not require you to modify the unit in any way. I really feel bad for all the people that gave this 1 to 3 star reviews. I wish they could know the satisfaction of having this be the 1 variable to no longer sweat over. I tried 3 different humidifiers, of the same size, before finding this 1 and there are no comparisons. You can't set the VPD or set trigger ranges, or timers on any other unit in this price range and or size. I have a small grow tent so size is everything. I just hope anyone who was not satisfied with this purchase gives them a second chance because it is hands down one of the smartest purchases I have made for my tent.
