I don't have any idea what you are trying to say. Push 1 for english. If you are stating that using MH all the way is not an original idea then the answer is "No shit!?! But that is not the point here. The point is that many (most?) prescribe using HPS for flower and while HPS may produce a larger yield, MH produces a better quality one in my limited experience. At least with my strains the difference in trichome development is obvious and indisputable.
Got Milk 
good luck this is all in ( MOO) My Own Opinion
I respect that. However, I already acknowledged the fact that quantity is won by HPS. (I am still in the new grower mode of bettering quantity every grow and my HPS grow was no exception while the current MH grow looks to be beating it...just not all or only a light thing). The science is with HPS there. I believe the science is with MH when it comes to quality. HPS does not emit the UV that MH does. I have witnessed a large difference in trichome development. I will heed your thought concerning the last couple weeks though, as my HPS grow was so trichome lacking that I gave the last 25 of 75 flower days back to my MH.IMHO. If you think MH is better in a flower room than HPS. I have tried both and HPS Blows the MH Away, I had 2 600 mh and they worked but the bud was not nearly as big and potent as the HPS dd, I have tried everything over the past 20 years, CFLs, 1000s watt HPS, LEDs. and IMO the 600 watt hps work the best, I would like to say that I have used both in my bud room a few times MH and HPS and the buds were harder more dense but the potency just seemed to drop a bit, the last few weeks under the HPS tell the story. Good Luck and this is just My Opinion.
Certainly does. UVA, UVB, and even UVC. In non-growing/reptile lighting applications, I understand the bulbs filter out much of it.
...which means that unless you shatter the outer glazing of the lamp, you won't get any.
I think it means that if you utilize a "non" growing specific MH, "you won't get" much.
I have a 600W and it was purchased over a year ago and I do not remember the brand ... But it was midrange in the price arena and grow specific. I will try to pull the invoice.
All I can tell you is that everyone who has tried the results of my CDM flowering runs has thoroughly enjoyed the appearance, aroma, flavor and effectiveness of the medicine. I've been replacing HPS lamps with them so my friends and patients are well aware of what that was like- and the verdict is unanimous.

i had a 400 w CMH a few years ago. philips retro white hps. had great results but the 400 was too small for my room. too bad they don't make those bulbs anymore. they went to the 315 LEc instead. same deal though, needed a magnetic ballast to run it.
I think UVB supplementation is a fascinating idea, please let us know how it works out, no matter what you pair it with!
The 315W LEC/CMH is a great lamp with an even better ballast, which is why it's more expensive than 860W CDM. You do get what you pay for, the small one produces a lot more output per watt than the big one. Lasts even longer, too.
