My (perfect) method for starting seeds
I have shared this before, I know. I use 16 oz. clear plastic beer cups. I use a soldering iron to burn drainage holes in the bottom.
I fill the cups with about 2" of seed starting mix and poke about 4 seeds in each cup. The cups go on a tray in a south facing window with a plastic cover. Once they germinate, the cover comes off. As the seedlings grow, I back fill with soil. Since the roots grow all along the stems, you will have a very sturdy plant when it is time to transplant (and you can see the root development.) (Oh, I pinch out all but the strongest plant in each pot.)
