I would as some people have suggested vegging with cfls. all you need is one decent daylight 35 watter for one plant and maybe two tens for side lighting and you get tight as hell node growth cos you can keep the bulb so close,then when it's time for the flip get a cool tube and inline extractor and watch them shoot up.......thats how i did mine and you should see the bud sites already. I'm only really a newbie myself but hps and mh are way too harsh for seedlings and remember to give it a tablespoon to a tablespoon and a half of water everyday.......just my 2 bobs worth like it's worked perfectly for me twice now. Good luck amigo!
