I have one of their 4x4 tents. Just check the dimensions and consider if you want a taller tent with a little more height. I believe the 2x4 is only 60" high. The 4x4 is 80". Once you have the fan up top and hang the light, height can become an issue in the smaller tents. I'd recommend getting the tallest you can fit in your available space. Even with shorter autoflowers height can become an issue and better to have extra room than not enough. I went with the T4 fan. They are very quiet and it's plenty for my 4x4. Even the low settings (3-4) it pulls in the tent sides a bit. Do some research on their inline fan T series controllers. They aren't quite as "programable" and useful as it might appear and unless you upgrade to their new "Controller 67" which is a smart programmable controller. The inside probe with the outside temp and humidity readout is convienant on both types though. I have a
mars hydro light in a smaller tent like yours and it works but I went with a
HLG for the 4x4 once I researched and learned more about better light options. I highly recommend the
HLG lights and their Quantum boards in either turnkey or kit, but do a little research and you'll find plenty of comments on both brands. Good luck!
