I made this tray for starting some seeds in for the garden. It is the bottom of a flat of canned food. I lined it with aluminum foil for two reasons, one is to hold oversplash of water, and two is to reflect light to the plants when they start to grow and I put the light on them. they will get the light from all directions this way and lean into each other looking for light. I planted some lettuce, basil, parsley, oregano, and rosemary. If you like things like this come join our new forum at http://the-mans-cave.com and share with us.
