Lady Vapor and SeedKing72,

Thanks for your advice...

New question... the 800W system has two bulbs. So I could just leave one one of the bulbs turned ON... instead of turning them ON both.

After some time, yes, I would then turn ON both of the lights (3-4 weeks?).

So now, just to make sure... what do you think about the 1000W system?
This system includes two bulbs; one 600W HPS and one 400W MH. Could I do the same thing with this? Can I run them for the begining month with the 600W and then turn ON the second 400W ?

I know there's shitloads of questions, but I would trully appreciate your answers...
