Egg cartons, styrofoam/cardboard for starting seeds?

[nc4bo]

Got them and throw them away and wondered if recycling them would work for veggies like spinach, lettuce, onion or radish seeds..

Starter mix or potting soil, one seed per egg, punch a few holes in bottom.

Can't afford peat pots and other starter stuff and looking for alternatives. ANY alternatives.

Let me know if you've done it before and how you made out.

Thanks bunches!
