I just bought this ceramic metal halide that has the best spectrum i have seen. the spectrum goes straight across the middle no little spikes here and there just a fat wad of color. the local hydro store guy said its the best for vegetation and flowering. You dont have to change to a hps for flowering also it works in a hps ballast. i got a 400watt. its called hps-retro white ed18 made by philips.
