I'm no mewbie grower here, started growing when I was 15 and turned 44 last friday. 
Metal Halide on the other hand does put out some of the UV spectrum.
Please explain (getting this subject back on track) to me as to why the plants that I have seen grown in LED cabs are so scrawny and produce very little.
From the plants I have see under LED, you could do better growing in a computer cab under compact fluors.
My theory would be that certain hormones are not being activated within the plant, and would be due to something missing in the light spectrum being provided. All I am saying that plants need low levels of UV light in order to complete their cycles.
