Cool Tube???

I was thinking of purchasing the 400 watt HPS cool tube. Does any one have any experience with one. If so what are your thoughts? Also is it cool just around the glass or the whole thing is cool? B/C Im already having major heat issues. THX in advance.

bump ..........

No idea brother. Im purchasing a 600w saturday, and still don't know what to expect as far as rising tempatures =/

I don't have one, but from what I can tell if you have a good inline fan on it and are venting it outside of your grow area, it should drastically cut down temperatures.

make one. look in they diy or search i know theres a tutorial for a growbox witha cooltube.
