I know mj can be grown using both forms of lighting, but is metal halide really that much better for veg growth? Has anyone grown same strain using both mediums and kept a photo log?
and about hps, are they that much better for flowering? same followup question applies here...

also, i've heard about hps (special) grolux being used for veg...isn't easier to get the right spectrum by just popping in a conversion kit for a metal halide bulb?

one more...which is easier, metal halide ballast converted to use hps bulb, or hps ballast converted to use metal halide bulb? I'm a little bit confused about the whole thing...

thanks for any advice on this query
