Dude I respect you to the roof , but How can you even thing to grow with hps and dont use a cool tube??? Get yourself 2 cooltubes, and plug some extractor fan on it... I had 400w in cool tube fited on my carbon filter and pk125, It would be impossible to do attic grow without it in the start of the summer..
Short answer ...
HPS was only ever a TEMPORARY option.
Never intended to use it fulltime.
Don't want to throw more money at a technology I have no desire to continue with.
