Look no further, this is the best
This grow tent exceeded every expectation I had. I’m a research scientist by trade, and I spent years researching equipment before making this purchase. I don’t make decisions lightly, and I can confidently say I was not disappointed in the slightest. From the moment it was set up, the quality was undeniable. Everything about this tent feels intentional, durable, and thoughtfully designed. The materials feel substantial, the construction is flawless, and it creates an environment that feels professional and dependable, not flimsy or temporary like many other options I’ve encountered. The quality is truly exceptional. The thickness of the tent material, the strength and smoothness of the zipper, and the complete lack of light leakage immediately stood out. The instruction booklet it came with was exactly what I needed as a newer grower, and I read every page. Scanning the QR code and discovering the accompanying videos absolutely amazed me! They were clear, thorough, and incredibly helpful. My husband, who is a mechanical and manufacturing engineer, helped assemble it and was genuinely impressed. From an engineering standpoint, he immediately noticed the superior craftsmanship and smart design choices. That alone spoke volumes. What truly sets this tent apart is the confidence it gives you. I wanted to get it right the first time without needing upgrades down the road, and this delivered exactly that. After all the research and waiting, it was absolutely worth it. If you value quality, precision, and long-term reliability, this tent is an easy five-star purchase. I would buy it again without hesitation.

Top of the line tent
Such a nice tent! I wanted something sturdy and efficient and the 2x2 quality is well beyond what I expected. This was a good price for what you get, which is a little higher than most. I wouldn't change my mind if I could. The tent was super easy to install, and the tolerances are pretty tight which keep the sides from buckling too much. The rods used are metal and stong enough to put way more weight than needed. The vinyl window allows easy viewing without compromising the internal humidity and temperature. Alot of my electronics are quiet enough, but while inside the tent I can barely notice anything is running. Im expecting great plant growth due to the reflective material on the inside, allowing the plant to take in more light. Overall great functioning tent that I would recommend to anyone.

Buy it IF it's available!!!
Although I have owned lots of camping/screen tents over the years, this is my first grow tent. This tent is built better than any of those. I did lots of research and read many reviews and the most common complaints about grow tents seem to be light leaks and poor quality zippers. There are very few light leaks on a seam or two ( I would be willing to bet most tents will have some leaks ) and the zippers are heavy duty...as is the rest of the tent. The poles fit together nicely with a good solid click from the buttons. No redrilling of holes. From the way the tent is packaged (NOT stealth shipping though) to their storefront (nice professional website,with words spelled correctly!) everything screams quality. Even though I assembled it alone, it went up fairly easy. Like most other tent makers they assume you are assembling this in a 20x20 wide open area, which I wasn't, so you might not be able to lays things out like in the directions. I assembled the frame from the "ground up"as I did not have the room to build two halves and put them together like the directions read. Putting the cover on wasn't hard...just take your time and you shouldn't bend a pole or tear a seam. Though that may be hard to do as well as this is built. I like this tent so much I bought the 3x3 to use for a drying tent. Probably overkill for that purpose but I could not NOT justify spending the little extra $ to get this much more quality. I had ordered a competitor 3x3 tent and sent it right back. Weighed about half as much and poles were only half as heavy. For the few extra bucks.... All in all I don't think you can get a better bang for your buck. It might not be GG quality as I have never seen one in person but it's nowhere near as expensive. I also bought AC Infinity duct fans, carbon filters and ducting and ALL were packaged solidly and looked well built. Very happy with these purchases. If I would change anything about these tents it would be these few things (which seem to be common in most tents) 1. Additional hanging bar(s) or the ability to purchase them. 2. Doors that zip 3/4 of the way around the tent. I can see it from an assembly standpoint but I prefer to go inside my tent to tend to the plants and don't need all of that access to the plants from the outside. I would think that is a lot of weight for the zipper to support and might be a source for future light leaks. 3. Observation window? Why not just unzip the door a little bit and peek in? I wonder if a long vertical zipper in the middle of the door to peek in and slide into the tent itself to tend to the plants would work. You also have to unzip the door quite a ways to take advantage of the hanger to keep it out of the way when you do open it. More than I care to. The inside storage pouch is also located on this part of the wall that zips away. Could be on the opposite wall which is fixed in place. 4. Would like to see top ducting ports located a little higher. Just a few small things I could think of that would work better in MY situation. Everyone has their own ideas. I do know this though...after doing the indoor gardening thing for about 6 years now I can unequivocally give this piece of advice - Buy the best equipment that you can afford!!! I tried to re-invent the wheel and go the DIY route but in the long run it costs way more money and lots of lost time and effort. The old saying garbage in, garbage out holds true here as well. With quality equipment you can control your environment which is number one to successful indoor growing in my opinion. One more thing that tent/light manufacturers could come up with is a better system to hang filters, ducting, fans AND lights. The wire hangers, filters straps and ratchet hangers with carabiners is cluttered with ropes dangling everywhere and just not very "user friendly" especially for us old farts whose hand don't quite work like they used to! One more nice touch from AC Infinity is the fan control mount on the outside of the tent which allows for adjusting fan speed without having to go into the tent. All in all a very solid buy. HINT: check some reviews on YT and you might find a 15% discount code for an even better deal!

Perfect for 3d printers!
Exactly what I was looking for for my Bambu Labs 3D printers. I paired it with the AC Infinity S4 fan and it works great for venting out the window. I also added a 20” x 44” piece of sanded plywood to support the rack. This is the 24” x 48” x 72” grow tent—very sturdy, thick, and high quality. Tip: If you have a pole that won’t click into the other, push the pin completely flush from inside the inner tube with your finger. It should become springy again. I’ve attached a picture for reference.

Best tent on the market!!!
Excellent tent by far and I've had several ones in a higher price range. GG, SF superior quality. Even the weight when it was delivered, came on a freight truck with 2 people carrying it. Set up was pretty easy definitely need 2 people. Zippers are good has a lot of ports to set up your exhaust sucks, heater, definitely no light leaks that I can tell. On e I received it and put it up I went Ac infinity all the way!! Extremely satisfied and with all the stuff I've bought from AC infinity nothing but the best. Next on my list is the evo8. I'm using the 69 pro controller and just blown away app is easy takes a little time to get everything just right. But when you do set it and forget it. Keeps the environment exactly where you want it. Won't buy any other product again. Ac infinity all the way!!

Honest review... Seriously.
So first off it's actually a great tent. Well, wayyyy better than the "3X3" tent that I bought that was supposedly cheap and I bought it and it WORKED, a few light leaks here and there but not actually on this ac infinity tent. I have had time to adjust to what I want/need with a grow tent and this 99 dollar 3x3 ac infinity tent, I actually have what I need like all kinds of ports up to 10 inches so my 6 inch ducting works but a little over kill for what it is but it's there. Fabric is obviously not a thick as a gorilla tent but it's millimeters off! It's pretty thick stuff and the zipper is pretty smooth and don't get stuck and make a bunch of fuzzies around the little lip where the zipper is. Super easy to assemble as you can See. Would recommend to someone who going to buy a grow tent. If there is a grow tent that seems the same compared to this one and it's like 20 dollars less than this one. spend the extra 20 dollars! do it. Anddddd lastly they claim the cheap tents are like a 3x3 ect.. they are not. The ac infinity tent is actually 3x3 unlike this "cheap one" I bought it's like 3 inches off and that makes a huge difference. Hope this helped and sorry you had to read so much but just know this is an honest review that is not payed or influence by anyone but myself and what I've experienced in my life.

Great tent
I’ve used there tent 2 times now my wife loves to have a garden inside during the winter the size was a great choice as it left lots of room in the house and zippers and overall quality was amazing no holes or tares and the Velcro for the doors was just amazing idea with lots of room for your plants to grow can’t beat the price
