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

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.

i love this product for my indoor grow tents. i use them on my 2x2 and my 5x5. it doesnt seem to struggle at all to heat my 5x5 just the same as my 2x2. amazing product, highly recommend, especially if you have an AC INFINITY Controller to pair with it. i use the AI controller with CO2 sensors and it is an amazing pair

I keep my house cold, so keeping tent temps up while lights are off has always been a problem. This simple heater has been an absolute game changer for my grows. AC Infinity stays at the forefront of innovation for us home growers and I’m thankful for them!

Talk about easy. I plugged it in, inserted the tubing and the sensor. It took a minute to figure out all the menu options, but I really only needed to hit temp up or down. The additional options will be useful as I advance further with my efforts. It doesn't seem to get too hot on the base. It is very quiet. It feels solid. I haven't noticed any smells or other oddities. Just plug it on it.

Works great cept after a few days it has gotten louder.

I use this to keep the temperature in my grow tent at a specific temp and this heater has not failed once. I use these with my AC Infinity control hub so I can monitor the temp. It's always spot on, or if it does vary, it's only by 1 or 2 degrees. Not substantial enough to worry about. There's going to be some deviance. The unit itself seems fragile. I wouldn't suggest moving it around too much. The unit does not overheat either. I check it periodically to ensure it isn't overheating since it's on 24/7. I highly recommend the AC Infinity line of products (even though the are a Chinese company) because their devices all get along nicely and I can monitor environmental conditions whenever I want to. I wanted something I could use to manage all the devices in my tent, to include the grow light, the humidifier, the heater, the fans, and the dehumidifier, which is NOT an AC Infinity product. Also, I can easily scale up if I want to use a bigger tent. Overall, it's easy to give their products a 5 star rating, for now. We'll see how durable these devices are after being used 24/7 for a couple of grow cycles. Maybe I'll revise this then.

This little unit works so well! I bought a second one for a second tent! Every item from AC Infinity works flawlessly with the controller. 1st tent is a 4x4 with 7 plants the second tent is a 2x4 for flowering. It keeps my 4x4 perfect so I know it will handle the 2x4 tent! In the APP, select "buffer" I have a 6°F buffer, so it doesn't just turn on and off repeatedly. So my Temp is set for 75°F, add 6° and the heater will rise to 81°F and shut off but will not kick back on until it reaches 75°. If there was no buffer the temp will be set at 81°F and as soon as it drops below 81°F it turns back on. If you have the tent in the basement or somewhere else that is cool you definitley need to use the buffer.
