Hi clayboy,,
Would be better if you could try and get your hands on a 250w a least,, HPS.. I brought mine brand new of some think like £70 ish,,
Just make sure on temps in your room sit at 75 80 still when the lights running,, well you know that anyway,, I think 2 of the 42w bulbs would be ok still grow but no way near as good as with HPS,, Mine done give of that much heat,, but after a few hours of running it builds heat big time,, so needed fan...for a few extra $,,,, and few more qwid on the electric,, and there you go.... well worth it...
