strange seedling

Is it standard to put the seedling under the light for 24hrs?

Well 24/0 photoperiod isn't a neccesity. Some use the 18/6 or 16/8. Some studies have concluded that there is more root growth with a dark stage of the photoperiod. This does slow photosynthesis naturally because light is a part of the equation. I have heard many growers say they don't see much of a difference.

Good point break the seeds in gently then you can flood them with light.
