If you want the to grow faster then leave them on 24 hours. If the bills are a concern of yours then switch to 18/6. If you want to switch to 12/12 to know the sex then do it and, yes, you can switch back to 18/6 after you determine sex but this is going to add time to your grow. It will take the plants another 1 or 2 weeks to switch fully back to vegetative. Then you can grow them taller and then flower them. I would get them all to 12" to 14" then flower them on 12/12 and pull the males and let the females show you what they're made of. lol
