Recycle Seed Starts

The last two weeks have been really warm so of course I got my seeds started.
We have snow today but the seeds are started and will be moved to the cat buckets under plastic in about 3 weeks.
My seeds are started in egg cartons inside recycled cake containers.
I set them on top of the freezer or fridge for a few days until they sprout then move to a towel on the kitcken island for another few weeks.
You just lift the egg cartons out cut apart and plant straight into the soil when there ready.
