All it takes is a water bottle and swiss army knife to make this wonderful self watering container. It operates just like an Earthbox. Its very easy to put together and is very low maintenance. It'll make growing plants so easy you'll want to grow an entire garden.
Step 1: Gathering Supplies
This is a very easy build, and many ways to modify on to it which i will show after. So as for the supplies you'll need.
1. Water Bottle
I suggest getting one that is shaped like an hour glass, they tend to hold up better and provide and excellent base to build upon.
2. Swiss army knife
I used the tiny army knife in this instructable, but I found the larger red army knife better because of its reamer. It makes the hole punching part much easier.
as for the mods, you'll need:
black heavy trash bag
