I have a small side kali-mist grow under 209 watt CFL's (104w 6500k and 105w 2700k). I've thought of replacing it with a small metal halide but was wondering the difference in UVB they emit. Ive seen color intensity charts but none speak of UVB. I also saw "Reptile bulbs" claiming 10% at 10$ a piece. Can anyone provide some insight to this? Is Metal halide the best source of UVB?
