To create a basic modular planter out of an aluminum can, here are the steps:
1. Clean the Can: Rinse the aluminum can out thoroughly with warm water and soap to ensure it's clean and free of any residues.
2. Drainage Holes: Turn the can upside down and, using a drill or nail and hammer, create a few drainage holes in the bottom. Be sure to wear safety gloves during this process to avoid any sharp edges.
At this point, you have your basic, vertically oriented aluminum can planter. Now, let's discuss some incremental ways to upcycle this planter:
1. Wicking System: A wick can be added to promote better water distribution to the plant roots. Thread a piece of cotton string or rope through one of the drainage holes so that one end sits in the water reservoir, and the other end extends up into the soil. The wick will draw water up to the plant's roots as needed.
2. Connecting Planters: You could create a system where multiple planters are watered by PVC pipes or hoses. The water would flow from the drainage hole of one planter into the next one below. You'll have to angle the planters slightly to ensure the water flows correctly.
3. Decorative Elements: To further improve the look of your planters, you could wrap them with fabric, rope, or even paint them. This not only adds aesthetic value but can also provide additional insulation for the roots.
4. Mounting System: Lastly, you could design a mounting system for your modular planters. They could be connected to a wall or a vertical panel with hooks, for example. This allows the planters to really take on a vertical, space-saving form.
Remember, when adding anything to your planter, ensure it's non-toxic and safe for the plant. By following these steps, you can upcycle aluminum cans into a beautiful, functional, and eco-friendly modular planter system.
