Pour enough soil into your seedling tray to fill each seedling well completely. Level off the soil with the side of your hand. Pick the tray up a few inches and drop it a few times to help the soil settle. Top off the seedling tray if necessary.
Place a dried corn kernel in the center of each seedling well. Press them about ¼ inch into the soil with your finger, covering each seed completely. Water until the soil is totally saturated but not muddy. About a cup of water per every six seedling wells should do it.
Set your seedling trays in a bright, sunny area. A windowsill that never drops below about 50 degrees Fahrenheit works well. Daytime temperatures should reach up to 70 degrees Fahrenheit. You should see sprouts in approximately three weeks.
