I´ve got myself a Ruck 125L axial ventilator 355m2h with speedcontrol, a 400w HPS, an active carbon filter and a 125mm d cooltube.......what´s a good setup to achieve the best cooling results?  

I was thinking: suck through the filter, blow through the tube, then exit my growbox using ducting.

 any feedback would be gratefully received!! thanks

most growers with cool tubes will suck air from outside source and return same air to same place. In other words, the cooltube air is completely isolated from the grow area. A few will suck air from the grow area, and exhaust it to an area outside the grow. I would choose the first method.

thanks Milehigh,, 

"the cooltube air is completely isolated from the grow area" 

that sounds like a good solution for my heat problems!

"don't u need in and out air for the grow room?"

yes of course you do,,,, I´ve got two small  155m2h axial fans that will be used  for the necessary ventilation/extraction...

I came, I grew, hmm I forgot....
