Trying to learn all I can about lighting right now. Have been looking over HTG supply and had a question about bulb quality and spectrum of the major brands. High Tech Garden Supply How important are the "sub" colors like violet, yellow and orange? Would any good HPS have a complete balance of all the spectrums or are some inherently more complete and balanced than others. I wouldn't want to get a bulb that is just "red". All the big HPS brag about their quality for flowering but they don't say much about the overall characteristics of the light their bulbs produce other than "it's a fantastic light for flowering" and only mention "red". Also, some of the HPS bulbs boast an increase of x percent white spectrum over other bulbs which seems to mean they would do a good job of vegging also. To put it another way, I'm getting very good vegging off six 26w CFLs for two plants so a 600w HPS(90,000+ lumen) with at least some white spectrum seems like it would do at least as well and wouldn't require an MH bulb for vegging? Are the hybrid/dual arc bulbs that combine an MH and HPS in one unit a good idea? And, if a real good HPS also has a significant or adequate amount of white to veg would a dual arc be cool and great but unnecessary? Thanks.
