How many of you switch back to a mh the last 2 week of flower to mimic natural light spectrum outdoors

Just switching to a regular MH bulb did not seem to make much of a difference but adding UV does wonders for trichome production. I was running a Solistek 10k mh which also provides UV spectrum but after 2 bulbs blew out in just a few months I went back to the hps. I was using it as a main bloom light but guess it was designed for finishing only.
Now I run a T5 with 2 agromax 10k finishing bulbs and 2 hortiluxe power veg UV + FS bulbs which kick ass. It's like a supplemental light in addition to my hps so I place the plants closest to harvest under it fir the final few weeks. Really increases trichomes and speeds ripening; gives super rock hard nuggets even after just 9 weeks in bloom.
