I had spent the past few weeks saving up the biodegradable egg cartons (not the icky plastic, but the compressed paper kind in which you buy free-range, organic eggs). These make great "starter pots" because once the seedlings are ready to transplant, you place the whole container into the soil. The roots easily grow through it and it biodegrades quickly into the garden soil. There is a lot less disruption to the roots and to the plant itself since it gets to keep some original soil.
