what i want to know is what is the heat difference?
and what is the smallest grow box size u would use for each..

go with the 400 more light, bud bigger the light,go with 4.5 ft smallest if you have a cool tube great connect it with a fan ducking box

For that size room you need 18,298 lumens, the 250 watt should do fine.

If u can, go with the 400, more light = more bud!

Unless he cant keep his heat down, more heat = less bud.

Ture, well buy an inline or sumtin. I run a total f 1200watts in a 5x2x8 area and my temps stay at acceptable temps, usually around 75-78 during the day with lights on.

For $20 more it is hard to pass up.
And i agree 100% I have the exact size room with 1200 watts.
