Idk if I would say the best. Im really interested in the gorilla grow tents because of the height extentions. Thats something ac infinity doesnt offer.
But for what you pay for ac infinity seemed well worth it. I did a bunch of research on tents, vivosun, mars hydro, and spider farmer. Originally I was gonna buy a complete kit. But I knew I wanted to possibly expand in the future and ac just seems to have the easiest user interface, along with functionality. So I purchased a 3x3 tent, with a 6in exhaust and filter, and a 4x4 light. So when I upgrade I can buy a cheaper light and exhaust system for the 3x3 and just by the tent for the 4x4. Plus the added par values of running the oversized light helps keep power consumption down during veg and early flower. The ac 3x3 kit comes with a 4" exhaust and filter
Since Im running everything I'll break it down by component starting with the tent
3x3x6 is what I have. I know they say their tent poles are yadda% thicker or whatever. But they are like the standard hollow tubes with spring loaded pins to keep everything together. They are sturdy though, I pulled my tent with plants in it all over the basement amd I never felt like it was gonna break. Reflective walls are just about as good as they get with the material all companies use so theres nothing to complain about there. As far as my first tent I could not be happier. Mine isnt the newest though the newer had a side door. Thats the only thing I wish I had for ease of access during defoliation and watering
The light I will admit I was iffy about. Its their 400w 4x4 version and were relatively new to the lighting scene. I went with it anyway cuz I wanted it to eork with everything and the stats were a little better than most lights in its range and you can see the results for yourself
The exhaust fan is great too I upgraded from the reccomended 4 to the 6 inch for my set up just cuz I wanted to run quieter at lower powers. My tent as full as it is has never gone above 60% power. Nothing more to say about this. Its definitely serving is purpose.
Filters are gonna be a toss up they are well made and any filter you choose will work as long as you're operating in its specifications.
6" clip fan is great as well. Like all ac electronics it can be plugged into their controller for even more control options than manual use. Moves a lot of air at full speed
The controller 69 is what makes ac infinity shine in my opinion. Their individual products are good, above average actually but when paired with the controller 69, either Bluetooth or wifi version makes everything 10fold better. Im not kidding either, you can run individual programs for each of the 4 possible connected devices. Set things to either ramp up or ramp down when conditions aren't favorable in the tent depending on the needs, including the light (controlled by temp/humidity thresholds). Also gives you graphs on temp, humidity and vpd conditions with readings taken once every 15 seconds. Honestly its the best complete kit you can buy in my opinion for the money spent in my opinion. You get everything you need to grow including 5-5gal grow bags.
