Hey guys. I just upgraded to 400 watts from 250 w and i'm just wondering what the are the best bulbs out their? I was thinking Sun Master or Son Agro, So if you guys can give some recomendations for a HPS bulb and a Conversion MH that would be great although i'm thinking of making my ballast switchable so i dont need to run a conversion. Anyone know of any good articles on making your ballast switchable? safely. Thanks guys happy smoke.
