MV???

Are you serious?

If I am not mistaken, MV is the second worst light source from an efficiency standpoint next to halogen lights.

Sorry, but there is no way you will find that MV is better than MH for vegging...or good CFLs for that matter.
HARDDON Reviewed by HARDDON on . New log, six plants, first time vegging w/HID All my previous grows were done with cfls and floro tubes, However this time my seedlings are under my 2 175w coated MV lamps and cfls, I finished the remote ballasts and re-oriented the bulbs in their reflectors this week. I must say I am quite impressed, all six seedlings cracked the surface last week under 6 cfls at 18/6; after that week my new hid setup was ready, within 2 days under these lights, all six have a first set of internodes, this never happened to me on previous grows with Rating: 5
