room temp is fine, maybe a little more. like 76F. only water like once a week or stick your finger a few inches deep. if it's still wet, do not water. pot likes to dry out some be4 more watering. for light, right now you're vegging so i'd leave them on all day and night. at least that's what i do. when you go to flowering, do 12/12. idk about humidity. i don't worry about it. i have 2 1week old plants. idk if this stuff is different for clones.
