I prefer MH/HPS to MV. It's the lowest lumen output of the HID lighting.

There's enough charts on the boards, i cant be bothered to find one, but MH/HPS are better then MV
LIP Reviewed by LIP on . Mercury Vapor light I was in my Wal*Mart and saw a 175 watt Mercury Vapor Bulb 4 $4.75USD and a Light fixture 4 $22.97USD... Will a Mercury Vapor light work for a indoor grow??? If so what are the +'s & -'s of this sort of light... Thanx Rating: 5
