greetings,

I recently followed the tutorial you posted for the DIY cool tube with the white reducer. I have a 400w HPS that I am having a bitch of a time cooling off. I saw your post on my thread. What kind of temps are you getting on the tube itself? Ambient? And what wattage of light are you using? I know i will get this ironed out. I'm gonna search to see if you have an album up so i can see your rig too. U pull through carbon scrubber , in line w the tube too?

many thanks,
Andy
