Review: Elegant and sturdy - Quality I expect from AC infinity - 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.
Review: Works great!! - Heater is easy to use and set temperature. I have a 4x4x80 in my garage and keeps it at 77 . I’m from the northeast so it’s cold at night and does run more with out the light on to keep up with the cold. Heat out put is good.

### ⭐⭐⭐⭐⭐ Nothings better than AC INFINITY!
*by M***S on December 12, 2025*

This is a game changer for your grow room. I have a 4x 4 grow tent. I had a consumer heating tower that worked, but definitely not as well as my new AC INFINITY heater. I’ve plugged it into my AC INFINITY Ai controller and life is so easy now. My grow is slamming now and I can sit back and relax, my plants are thriving!
