Hi, Basic: when my seeds pop, I put my root riot in a net pot with leca on a raised stand under the lights. I make sure it stays moist, so because the root riots are under lights now, I check on them 3 times per day to make sure it's moist and won't dry out roots.
I don't know what your grow medium is, but I'm hydro, so before I see roots begin to peek out the bottom of the net pot but the seedling is growing strong, I put them into place in reservoir lid. I continue to hand water until roots are well into the water. I spray water into the net pots from below, to encourage roots to come down. I say you can't pay too much attention to seedlings.
