  1. just noticed today that my Metal Halide lights bulbs i bought when i started are 5200k.. not 6500k.. is this gonna make alot of diffrence
  2. not at all MH lights dont go up to 6500k only cfls do
  3. so whats the best k temp of MH to get ? also the best HPS ? i have another MH with 4100k.. will it suffice ?
