THERMOFORGE T3, Environmental Grow Tent Heater with VPD Temperature Controller, 10-Level PTC Heating and Included Extension Hose for Tents, Rooms, Greenhouses

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.

The adjustable power output and low wattage is perfect for a grow tent. No worries for accidental fire as the wattage is low enough to deny ignition and the anti tip shut off works 100%. Never deploy more than a 500 watt heater unattended. This unit fits the bill for set and forget.

I bought this, the AC Infinity AI controller, the Humidifier and own 2 inline fans. With just this a pull fan and the humidifier going with the AI controller i watched VPD be kept in perfect check. I'm normally terrible about this and just set a Temp. The heater has a flex tube you can adjust to blow into a room or just heat the room its in. The screen is easy to read and use. The screen turns off and is controlled by the AI controller if connected, which is fine honestly. The quality as as you'd expect. from AC infinity, elegant, smooth and feels sturdy. It worked for over 4 months off and on automatically and worked great. It definitely uses far less energy than the radiant heater I was using and probably paid for itself. I love AC infinities feel and quality. If you are in the market for a grow room heater then this is worth your money.

I Hooked my T3 up to the AC infinity AI+ controller via UIS Interface and it performs perfectly well in 4x8 set up. It is a little smaller than what I actually expected, which in my case is a benefit due to the smaller footprint. Hard to go wrong with AC Infinity, I have been using enough of their products enough time now to truly appreciate the company and their quality gear. It Works Great!

I grew 3 plants in my unheated garage during the frigid temperatures we had in ohio this past January when we had many nights in succession of temperatures between 0 & -22f. This heater kept my plants at 60f-65f during overnight hours and no problems during the day maintaining temps of 72f-78f. Inside my garage it was in the 30s when outdoors it was 0f to -20f. I am very impressed with this heater.

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

This tent heater enabled me to do a winter grow in my unheated basement, in Maine. The combination of the heater and the lights enabled me to keep the temp around 75 degrees. With the lights off, the heater could keep the tent around 60. Luckily, with autoflowers, i only kept a couple hours of "night." The amount of control settings on this heater are incredible. A little confusing at first, but once you use it, it is pretty self explanatory. I hook it up with rhe 69 pro controller, so I can monitor and adjust the heater remotely. The tent size is 42x42 inches. The basement temp is around 45 degrees.

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.

Effective heater with tunable output.

Quiet and efficient, I have no complaints!

Super Gerät mit dem Controller AI+ muss man sich um nichts kümmern da die AI alles übernimmt. Einfach zurücklehnen und zuschauen wie alles wächst und gedeiht

Delivered one day early than expected. Works very well and is very quiet. Easy to set up and it maintains the set temperature with ease. I'm very happy with everything

Love the heater just thinking I need to upgrade to a bigger one. Works great but I deal with -30+ weather so bigger is needed for me. I love all AC infinity products though.
