That's a 400w MH for veg in a 5" cooltube hooked up to a 5" vents TT fan (bearings are starting to go after 2 years), I flower with a 600w HPS in the same tube and the fan on full power (it has 2 speed settings) is JUST good enough to keep a 1.2m square tent temps between 25-30c in summer.
Cracking mate. I'm in a 1.2 as well so that's an ideal setup for me then. It's only a degree or two warmer here at the minute but I cant keep my 400 w under control now. If i zip it up it rises too 32 or more! You could heat your house with these things haha!
