Using egg cartons with peat moss or soil is a great way to start your seeds.
Here, I poked holes into the bottom of the 12 egg openings and added the peat.
I added basil seeds to each section, sprayed the peat with a small water sprayer, printed B A S I L on the flap to the carton, covered it with seran wrap and put it on top of the frig where it is warm and the seeds with stay damp.
I just have to remember to check on them daily, not to overspray so it becomes moldy, and not to let it dry out so the seeds will not sprout.
