Review: Top shelf gear for the home grower. Highest quality I have seen. So impressive. - AC Infinity has changed the game of home growing for everyone. This fan is priced very well for the level of quality and features it packs. I plugged it into my AC Infinity AI controller and it detected it without hardly any intervention. Since I am not growing plants, but gourmet mushrooms I needed to disable the AI (broke my heart because its truly amazing) and set it manually at the precise numbers I needed. High humidity and low CO2 for fruiting. I had trouble getting it to accept the numbers I wanted since I was not growing standard plants. Called support and had Judy on the line with zero wait time. Judy was a controller ninja and walked me through the clicks to get exactly what I needed set up. Perfection! She didn't ask a million questions, didn't have to go through a painful data collection pre call, just picked up the phone and asked how she could help me. I explained my issue and she had a solution in minutes. Made sure it worked for me and was a pleasure to work with. I don't call support for anything, even at work, unless I am totally dead in the water with no options. AC Infinity made me rethink this stance. The fan itself works great. 10 different settings. Perfect for a mushroom grow tent thanks to the true waterproof rating. Humidity won't even touch this thing. The fan looks sleek and runs silent. I see there is a sound damper available but can't imagine why one would need it unless they sleep next to the tent because its so quiet. The setup was quick and easy. It moves a ton of air and keeps the FAE spot on in my tent. I love the AC Infinity products. I already had a fan and filter and 2 humidifiers that I swapped out just so I could use them with the controller and have more matching gear. I want to set up a garden inside now since this system is so easy to use and works so well.
Review: Impressive and high quality - Honestly, incredible for the money. This company is providing some really interesting equipment at this price point. Perfect for my HVAC needs in a mechanical closet that needed some quiet airflow.
