Heck yes man!!! Good to see its working out. Post up specs on your space size, how many lights, etc. looks like you have it pretty well set up for a first run.
You should take the concaved light director in a flashlight or floodlight and place it right over the light to direct it down. This could give you many more lumens on the plants.
Sorry, forgot to post an update. I harvested successfully and got a little bit less than an ounce or so - I don't have a scale. It was some really good stuff My closet size was 2x2x6 ft. I've moved and am starting a small greenhouse outdoor grow next. The HIDs worked like magic though! I agree that some reflectors would have improved the output.
This is exactly the thread I was looking for. I have a small Rubermaid and am fearful of the thigh power HPS grow lights... I also have oh 10 or so power supplies around.
