To make milk jug lanterns, stick a string of colored lights in empty milk jugs. No electrician required.

This dome with walls made of upcycled milk jugs was built by Studio Klimoski Chang Architects, and is called “Head in the Clouds“. (Leave it to builders in New York City.) It is on Governor’s Island, and is open to the public for the summer of 2013, June 8 to September 22.

Irrigate just the roots of a garden by poking holes in a milk jug, and burying it. Add water for a slow drip of water to the roots of your plants. It’s a perfect solution for watering plants when you’re away for the weekend.

Plastic milk jugs make great mini-greenhouses or planters. If you leave the neck of the jug on, it’s a mini-greenhouse. If you cut off the handle and neck of the bottle, you have a planter in which to start plants, or even to let them grow big.

Cut up a plastic milk jug and label with a permanent marker. It’s a free and easy way to both upcycle and get yourself some durable plant markers.
