little seedling. 5 days old.... wondering about lighting

do i do a 12/12 lighting or just 24 hours lighting.

iv been doing 24 hours since it sprouted.
what should i be doing?

no no no , 12/12 is flowering cycle. 24/0 or 18/6 would be the best option, i asked that smae qustion 2day, the advice i was given " 18/6 for vegging tends to produce more females" so thats the way im gonna grow, just like u i have a new grow 8 days old, been doing 24/0 so far, just changed to 18/6 today, just need a timer....what kinda lights u using? any chance u can post a few pics. i wanna compare mine to others of the same age. im just growing some decent bagseeds but hey.IT ALL SMOKES
