agree that it looks too wet... for starting seedlings, or even small clones, you're better off IMO in keeping them in a small cube and small tray (a cheap clone dome) so that you can better regulate the moisture... rockwool should be wet, not dripping soaked... a nice cheap clone dome keeps the humidity a little higher too while roots and early leaves develop.

Yeah, 18+ hours of light, CFL is fine for now... I hope you have SOME light on them now lol... don't really understand that question about if it's time to turn the lights on...

Just upload images to imgur.com and embed em in the forum... easier than using the image uploader here
