I would get a 10 inch for 3 lights in that space, acoustic if noise is an issue.It will stick to 25-27 effortlessly.

Only the usual...

Tent size is irrelevant.

Work out the total lamp Wattage (add them up, so 600 + 600 + 400 = 1,600).
Work out the allowable temperature rise in °C = (desired grow temperature) - (incoming air temperature).

Look up those two numbers on the table at the top of this post: http://www.thctalk.com/cannabis-foru...read.php?48463

Where they intersect is the air flow volume required.

Get a fan rated at 25% to 50% more than that.
