You don't need fancy starter pots and lights to start your seedlings indoors--all you need are a few recyclable materials. Home gardens may be green in and of themselves, but you can make them even greener by recycling household items into tabletop greenhouses. These little greebhouses make educational projects for children and cut costs from your own gardening efforts. Plus, they're a cinch to make.
Rinse and dry a plastic soda bottle thoroughly. Remove as much of the label and adhesive as you can. Brace the bottle on its side so the bottom 4 inches or so is on the worktable. Cut through the bottle with a hacksaw, lining the saw up with the edge of the table. Set the top of the bottle aside.
Cut two toilet paper tubes in half so you have four cardboard tubes. Snip four half-inch cuts into the bottom of each tube. Fold the sections inward as if folding closed a coin wrapper. Fill each tube with soil, adding your small seedlings. Make sure the roots of each seedling are covered.
Slip the four seedlings snugly into the bottom half of your soda bottle; they should form a square. Add about 2 tbsp. water to each cardboard tube. Pinch in the sides of the top of the bottle with the thumb and fingers of one hand. Slide the top of the bottle inside the bottom of the bottle.
Place your new greenhouse on a table in warm, indirect light. Condensation should form on the sides of the bottle in an hour or two. Your seedlings should flourish in the humidity.
