After reading about ways to start seeds indoors, I would like to offer this suggestion:
Start seedlings in freshly-washed and lightly-bleached applesauce cups. Simply punch some holes in the bottom for drainage. They do not use much soil and can be reused.
I have started many plants using the above method. Of course you have to remove the plant before planting it into ground, but the applesauce cups will allow you to squeeze the bottom to bring the plant up to the point where you can grab it.
