YOU’LL NEED:

  • A two-liter plastic bottle
  • scissors
  • push-pin
  • rocks or gravel
  • potting soil
  • seeds of your choice
  • small amount of tape
  • adult supervisionGreenhouse Step 1

Step 1: Remove the label from the bottle. If the label doesn’t come off easily, fill the bottle with warm tap water until thewater rises above the label. Let stand for 10 or 15 minutes. The label should peel off easily.

Greenhouse Step 2Step 2: Measure four inches down from the plastic bottle cap. Draw a line and cut off the bottle top at this point. Place a thin layer of small rocks or gravel in the bottom of the bottle for drainage. Fill halfway with potting soil. Following the instructions on he seed package, plant the seeds. Water just a sprinkle—too much and you’ll drown your plants.

Greenhouse step 3Step 3: With a push-pin, make several holes in the top of the bottle cap. (It’s easier than it sounds.) Screw cap onto cutoff top of bottle. This is now the lid of your greenhouse bottle. Carefully place on top of the bottle, securing it with a small piece of tape on one side.

Greenhouse step 4Step 4: Set the bottle in a sunny place and wait for your seeds to sprout. When they get about an inch high, remove the bottle top and let the plants grow until you are ready to transplant outdoors or into another pot.

Note: Single-serving-size plastic bottles work equally well, only you can’t get as many plants in them. For these smaller greenhouses, measure down 31⁄2 inches from the top instead of 4 inches.

    Do you need a clear bottle, or could I use a green one from like 7UP?

    I had my kids do this at our last den meeting, and my son’s seeds are sprouting beautifully! We couldn’t punch holes in the lids, so we just loosened them, and it seems to be working nicely. We used Juicy Juice bottles. So, we’re reusing materials while earning our World Conservation Badges! This was a great, simple project that we can do over and over again.
