The first two answers were ok.

You don't need lights till the seed breaks ground. Keeping them warm (not hot) is mandatory, and depending on the seeds they should break ground within 10 to 14 days, depending on how deep you plant 'em.
Rusty Trichome Reviewed by Rusty Trichome on . Quick Questions Okay so theres a few things, If some one could answer this it would be extremly helpfull. 1...How long do you keep a plant at 18/6, Before you set it to 12/12. 2...Does it matter if you keep it at 24/24 up untill flowering. 3...And How much light do unsprouted seeds need to sprout, How long?
