Anyone use CMH in veg and LED in flower?

Ive been doing something similar for a couple years and love it. Veg under the CMH is wonderful. The plants love it.

I run a combo of alternating LED and CMH in flower. The two together provide everything and produce awesome flowers.

I run LED in VEG and LED/CMH in flower. As the temps start to drop I've been thinking of putting a CMH back into the veg. They are just an amazing light all around. I run the 4200k on the flower side squished between 2700k and 3500k LEDs

Only do it if your LEDs aren't working for you.

I don't see any reason to use any other bulb while my LEDs are around because it reduces my efficiency massively.
I can veg an area of 2m2 fully with around 500w of LED. I could never do that with HID or CMH
