2'x4'x5' tent 400w hps/mh

I'm wanting to get a grow tent that's 2x4x5 with 400w hps/mh electric ballast and two 6" inline fans 240cfm each. One for intake and outake. Do you think this will be enough air circulation to keep temps cool?

For a 400 the biggest tent I would get is 3x3. 2 250 watt hps's would be amazing in that tent. Use one of those fans just for cooling the lights (cooltubes) and use the other one with a passive intake.

That light is fine for that tent, even at 50w per sqft you'd be fine with a 400 in a 4x2 so I wouldn't worry about the tent size. Also, with two 6in inline fans you should have no problem cooling the tent. Do you have a cooltube or hood, or is it an open wing reflector?

I understand that thanks, I'm just saying a 400 in a 3x3 tent has better light spread than in a 2x4 ok?

Maybe a little better coverage but not by much, especially depending on what kind of hood you have for your setup. I think it was the way you worded it, you said "For a 400 the biggest tent I would get is 3x3", when a 3x3 tent is actually bigger than a 4x2 tent

Lol ya you guys are totally right my bad, to the op, your tent will be fine have fun!

Ok thanks for the help.

It will be the wing reflector. I have 134w of cfls at the moment I could add if need more light. 3 23w 5000k 1 65w 2700k 8700 total lumens. Have two under them now in Rubbermaid box until I can get tent.
