Reliable Performance Backed by Excellent Customer Support
Size: 530W, VPD Temp Controller
I’ve been using the AC Infinity THERMOFORGE T3 Environmental Heater, and it’s been a very effective and reliable addition to my setup. It does a great job maintaining consistent temperatures without constant adjustments, which makes a big difference when you need a stable environment. Once it’s set, it runs smoothly and efficiently. The overall performance is impressive—it heats quickly and keeps everything right where it should be. The unit itself feels well-built and designed to last, which adds to the confidence in using it regularly. I did receive a defective unit initially, which was frustrating, but the experience with customer service completely turned that around. AC Infinity handled the replacement quickly and with zero hassle. The process was straightforward, and I had a working unit in no time. Between how effective the heater is and how responsive their support team was, I’d definitely recommend this product.

Awesome for tents or rooms
Size: 530W, VPD Temp Controller
I was needing a heater for my 5x5 grow tent in my garage. Since I have been using AC Infinity for several years I decided on the Thermoforge T3. It is super quiet, has 10 different heat levels and can be programmed to maintain your desired temp. It comes with a long hose and can be used inside or outside the tent. Great quality and great value. I have since bought another T3 for my other tent.

Works great but settings must be adjusted right to heat
Size: 530W, VPD Temp Controller
My room was 60 degrees and the tent wouldn't heat to 70. I learned the off must be set to 0, the on to 10, and then you can set auto to what you like.

The auto feature
Size: 530W, VPD Temp Controller
So I ordered one of these probably a month and a half or so ago set it all up it was working okay for about 8 hours and then so I had it on the auto mode and it just would not show anything temperature or humidity or everything it promises to do it's supposed to sense that he on and off like a thermostat with this little bulb so I sent it back and it was replaced and then this one I've had going probably for over 3 weeks it was okay but one other thing I don't like about it I have a 4x4 can't it's not really big even on high with an ambient temperature of 61°, it could not even reach 70°. Inside and closed 4x4 mind you so yeah it'll work if you run it on on all the time but that's not the point it's supposed to on and off in the parameters that you set humidity PDF blah blah blah but it's doing the same symptoms the first one did except it took about 3 weeks longer and then it doesn't even heat that well it can't keep up in a 4x410 at 60 degrees it's even maintain 70 something's wrong there but anyway that's not my big gripe my big gripe is the same thing it just starts losing the automatic function which I like to set parameters for what the temperature is so I guess in a nutshell I would probably highly recommend steering away from this thing and I do like a lot of stuff about Viva son but that thermal proheater yeah after getting the second one and it does the same thing within 3 weeks yeah there's an issue there so I I rarely write reviews on Amazon and I ordered thousands of dollars thousands of dollars yearly from them and I probably only had about well since probably 2010 maybe five things that I've actually written a bad review about and I order a lot for my company and my personal stuff but yeah I would say no to this ever again so I'm a single back with the old little heater and put a thermometer in there and let that work because this thing is drove me nuts I've even insulated the thing the tube want again it's not if it can't keep up 10° difference at 60 degrees that's an issue and when it this is the second one I've had within them a month and a half to two months and an automotive just blanks out and that it will work on on the only problem is it's on all the time so unless you're going to sit out there and turn it on and off you're going to ruin your plants so yeah I would highly stay clear of this

Received dirty used unit that smells of cigarettes
Size: 530W, VPD Temp Controller
Item arrived used. Dusty, control screen wouldn't come on. Controller port was melted. The heater smelled like cigarettes. Im very disappointed!! I couldn't wait to receive this. Submitted for a return right away of the exact same item. I'll update this review when I get the replacement. Hopefully it's not broke and used also. UPDATE: Amazon did send me out another unit, got it 2 days later. This one was brand new like I was expecting. This heater is awsome for a grow tent during winter. Especially when you need the temp to be in the 80s for veg. I highly recommend this heater. Ac Infinity did a great job with this one! Updating to 4 stars for the stellar customer service from Amazon. Also for a top notch unit from AC Infinity. Would have been 5 stars all day had I not received the used one first.

AC INFINITY Has The Best Grow Equipment Money Can Buy!
Size: 530W, VPD Temp Controller
I love AC INFINITY products and their customer service is incredible! This heater serves as a perfect example, I used it every day, consistently in the New England winter and it kept my grow tent a perfect toasty 80 degrees Fahrenheit even when the temperature outside the tent was at least 50-60 degrees, it had no problems being in operation 24/7 for the entirety of winter and fall. I haven't tested above 80 because I don't have the need to but still it can definitely get you to temps below 85. Not loud at all, sounds like a fan at low speed so you wont get headaches from this, with the ACI Controller you can program it to do whatever you want, but even if you don't have one you can still control it with the actual Unit. I also bought one to use in my moms room to make sure her room didn't get too cold in the winter, helped the room get to 65-70 when the home heating couldn't! I don't see it having any problems next season, as it went months operating constantly without any issues, but ACI has great customer service and if anything DID go wrong I imagine they'd take care of you. As someone who has everything AC Infinity I can definitely say I back them up.
