eek... Used soil is very bad....Do not put them in the bathroom at night or you will get wicked stretching, when you are using artificial light it needs to be as close as possible without burning the plant. They do not require any light until 1-2 days after penetrating the soil. Leave them outside if it doesn't get too cold at night(mine survived @ 41 degrees F a few days ago, but this depends on genetics), and make sure you put chicken wire around them or animals might eat them. My seedlings usually appear about 4 days after I first plant them, good luck to you!
