started new plants

ight im started to grow again so tell me if this is right i germinated 6 seeds and they all came out just as i thought they have lil tails on them and then i put then im good soil n shit and i started to put one outside cuz it's a nice fukckin day outside to day and when it gets dark i bring them in and i have 3 lights set up and shit and i have one under the light inside n stuff and now im just waitin on till they start to sprout up i think it's like wat 2-7 days till they start to sprout up then after that im just gonna leave them under light for 16 hours then shut them off for like how many hours like 8 hours when i wake up do u think that will be enough time in dark for them cuz i need sleep too lol i put them in light at 9:00 a.m. and shut the lights off at 1:00 A.M. so is that good or bad...
