1. Start off by cutting a 2 liter bottle in half. You will also need another bottom of a bottle, but only about 3-4 inches. Make sure you rinse it out.
2. Unscrew your cap, poke a tiny hole in the middle, and put a cotton string through it.
3. Next fill the top half of the bottle with soil, seeds, and water.
4. Then fill the bottom part with water.
5. Duct tape all 3 parts together and you are done with your bottle biome!
