400W CMH, What Size Space?

Hey guys, I want to run a 400w Ceramic Metal Halide but I don't know if I should go for a 2'x2'x4'7" or a 2'8"x2'8"x5'3" Secret Jarden tent. I usually grow in 12" diameter, 5 gallon pots. I could grow 4 plants in either tent, but I wondering if having that extra space between the plants would be better and worth spreading the light out more?

Thanks guys!

the bigger the better .. wish i had a bigger grow space all the time .....

mines about the same size as the smaller one, and i think itd be nicer to have it just a little bit larger. maybe you can help me with my question?

yea more room for air flow and in general less stale air,will be way better

It's better to have it and not need it than need it and not have it. This is especially true with space.

Carry on.
