150 watts HPS and blue LED panel (since I'm still vegging at this point) and I can see firsthand what the deal is with HPS...OMG is that ever bright! Inner cabinet temps are at about 83F (after 8 or 9 hours uninterrupted) and the humidity is around 63%.

It was a bit of a challenge to install the remote ballast outside of the cabinet, but I figured it out. It is lukewarm to the touch, out of curiosity I placed a thermometer near it and it reads just under 73 F...

So far so good, and the babies seem to like it! :thumbsup:
