    • Great, durable humidity-level controlled easy to clean/fill humidifier with large water tank.
Size: 4.5L
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. ... show more

    • Awesome sauce!
Size: 4.5L
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! ... show more

    • Amazing humidifier
Size: 4.5L
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. ... show more

    • DOES ANYTHING YOU MAKE LAST??? STAY AWAY!
Size: 4.5L
I've already had to replace a circulation fan within 3mos, now your humidifier won't sync to the Ai module (don't get me started in the so called Ai! WORTHLESS) because the stupid cable doesn't work anymore! How can you not make a cable to last?? Please tell me!?! Of course, no regular S cable will work... Has to be proprietary.... WELL IF HAS TO BE PROPRIETARY THEN MAKE THEM TO LAST 6MOS AT LEAST! Anything electronically with the company SUCKS. The tent is OK but how much can you screw up some canvas and zippers.... I probably shouldn't say anything before the tent collapses! You want a tent, fine.... It's a tent! BIG DEAL... GOOD JOB WHOORAY! Get everything else to fill the tent elsewhere! The entire setup is worthless if I can't trust it, have to babysit it and constantly replacing things. This piece of trash is not even 6mos old! ... show more

    • Perfect add-on for small grow tent
Size: 4.5L
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. ... show more

    • VPD Management
Size: 4.5L
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. ... show more
