    • 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

    • 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

    • Very flexible humidity control with only a very minor design flaw
Size: 4.5L
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! ... show more

    • So good I bought 3!
Size: 4.5L
Review Image by Shaun Mirk
I bought the Cloudforge T3 to help regulate humidity for my indoor garden tents, and it’s been a total game-changer! The 4.5L capacity means I don’t have to refill it constantly, and the VPD humidity controls make it super easy to dial in the perfect environment for my plants. Pros: VPD Controls: The vapor pressure deficit (VPD) feature is amazing—it automatically adjusts humidity to the ideal level for my plants without me needing to babysit it. Large Tank: The 4.5L tank lasts for a while, even when running continuously. No more frequent refills! Quiet Operation: It’s super quiet, so I can keep it running in the background without any disturbance. Adjustable Nozzle: The 360-degree rotating nozzle makes it easy to direct the mist wherever I need it. Cons: It is a bit expensive. The sensors can be finicky needing to be reseated. Must use distilled or reverse osmosis water if you have hard water like I do. I’m really impressed with the CLOUDFORGE T3. It’s perfect for maintaining the right humidity levels for my plants, especially during the dry winter months. If you’re serious about indoor gardening, I highly recommend it! ... show more
