Step 2: Step one. osh.
then lay seeds in the carton.
cover the seeds with some soil, up to the bridges between the cells.
Step 3: When osh doesn't have what you need. step two. lowes
now place the cells into the lid and water the seeds. the lid will act as a support to the cells.
when they get wet, they will get weak.
Step 4: Almost done.
when plants are large enough transplant them into a larger container or directly into garden.
the egg carton is biodegradable and the soil will help the plant with nutrients.
Step 5: Notes.
don't know what to do with the top of the carton after planting the plants.
I'll update later if I think of anything.
Step 6: Update
as you can see the plants are tall and you can see how the roots find a way out of the bottom.
I cut along to row and planted it like that. makes planting corn easy.
