I have not read the whole thread so I appoligize if others already mentioned this; MH as appose to HPS. I have found in the past MH always gave me denser buds and also a little more crystal, but the buds are a tiny fraction smaller. This is my experience, although a lot of other factors contribute.
The factors that contribute to airy buds in my experience are: genetics, finishing not to early, light intensity, heat factor, nutrition and light spectrum and over all health of the plants. Just some off the top of my head, I am sure there are others.
