So far so good. Ive had 2 grows with this filter now. Im shocked at how badass this thing is. If I so much as open a jar for a sniff, in the house, it smells like skunk for a couple hours. But my grow room smells like a HOSPITAL. Im doing overkill for a 4x8 but that's what I was needing it to do. Id recommend ac infinity products all around. Ive had good luck with mine. Light control % sucks on their controller though lol. 10% 20% 30% 40%50% those 10% gaps are hard on some plants! I added tape to my ducting connections, painters tape. My garage smells SO GOOD! like a fresh hospital hallway. ... show more

    • thought was only Bluetooth ,it’s Both
Color: Black Size: 6-Inch PRO
Impressed right from unboxing at the quality look. The was intimidated by this whole tent set up and wow it adds up fast, but why cut corners. Love the automated monitoring. I’m read reviews that says it had WiFi and others that said Bluetooth. It looked to me like it was Bluetooth only. It wouldn’t connect so I sent I had to create a account, simple and fast. I notice on too when I was looking for any reset button or anything and noticed it had the Bluetooth symbol on one sucker and WiFi on the other . I tried again and it’s 2.5? Connection I’m not smart with this stuff at all. So mine had both , when I purchased it I thought it was WiFi the pro version but those reviews had me thinking otherwise. I was actually going to buy the WiFi lol So I hope they all have the same version for you as I got . I did it all on pad first and yes that’s the hard way but everything I did was twice lol . Pay attention to airflow direction when installing. I did not . The app is simple to use , i didn’t get hung up on everything my light I purchased won’t work with the auto dim. Doesn’t have the daisy chain option. I’m perfectly ok with that it will turn it on and off. I would honestly have all control over how high I turn my light. I bought the plug in adapter and it works great. I bought 2 of the fans /you will regret it if you don’t pay the extra little bit for isolation. this company Carrie’s works great with app so far items that look like thay come with the cheap controller like the fans have not so just pay attention and get the t8 for intake as well I follow the recommendations by ac and I have to return the 4 in and got anothert 8 on the way. For intake air. The 4 could not keep up at all the tent was imploding on itself lol . Was sucking in the sides bad lol. I got thier 5x5 tent as well. I looked at a lot and to me this looks the best. I am honestly only wanting to grow tomatoes all year hahaha . For what I have spent I hope thier good. If not I spent more for less . This I mean everything that this company makes if great( my memory bad I forget company name) lol It’s all quality. No light shine in mine not a big concern how I’m using it . But was dark as I have evidence like last time I seen this dark I was on a cave tour and they shut off lights for a min to show how dark yep that dark . Haven’t used the self watering planter pots yet of course but they look quality and I figured get now because they probably going to sell out would be my luck. Honestly I have never did anything like this garden in yard yes every year . I can’t compare it to anything and that doesn’t help you trust my opinion and I get that 100% I can say I’m glad I don’t have to be thinking I wish I would have went with another brand . I’m am on 1-10 a solid 9 nothing is perfect so never a 10 for anything. I won’t like paying the bill but I like it more than paying for junk. Sorry I’m so long I’m tired and bored haha. Bottom like give this company a good look over I’m happy with what I received. I don’t know you or you me . I am giving my opinion as I would if a friend asked what I thought. I hope you get whatever product fits your needs the best this is definitely one to consider. Take care everyone ... show more

Color: Black Size: 6-Inch PRO
This combo is great and very reliable. They run the quietly as to not disturb anyone in the next room even at full go. Easy to use, hand and assemble. Great value for the money and AC has great customer support.

    • Installed and Impressed – AC Infinity Delivers!
Color: Black Size: 4-Inch PRO
The media could not be loaded. So far, so good – very impressed! Just purchased and installed this and I’m already loving it. The noise level is super low – honestly, it has that peaceful white noise vibe that’s actually kind of soothing. Hopefully my plants agree! Installation was a breeze. We decided to mount it on a 3ft piece of 1x12 board and added a small square board on top to give space for the carbon filter – used the included straps to secure it—worked like a charm. Love everything about AC Infinity so far, especially the app! It’s super user-friendly and packed with helpful tips and tricks. Definitely happy with this purchase! ... show more

    • The fan is unreliable and lacks durability.
Color: Black Size: 6-Inch
After three months of use, strange noises started, and the fan speed decreased. It must be set to level 7 to spin properly. Update: The customer service was excellent; they responded and promptly sent a new fan.
