The way that I am making these uses 2 or 3 liter soda bottles and it supplies the soil with just the right amount of moisture for the plants to grow. It's a little different than bbullet's way, but it's still made with recycled bottles and produces fantastic results all for the cost of a pinch of seeds!
Step 1: Materials
- One 2 or 3 liter soda bottle with the cap
- A piece of newspaper, a piece of plastic from a bag or a piece of aluminum foil
- Cotton string
- scissors or knife to cut the bottle
- a drill (or something similar) for making holes in the cap
- tape (optional)
Step 2: The cap
I drilled one large hole in the center of the cap and eight smaller holes around it. The large hole is what will hold the string and the smaller holes will allow water to drain out.
Step 3: The wick
I cut three equal lengths of string (about 15 inches long) and tied them together with a simple knot about 3 inches up from the bottom.
Into the cap, I fed the three short lengths of cotton string through the big hole in the middle of the bottle cap and pulled them through so the knot rests on the hole on the inside of the cap. The short ends will dangle in the water, and the long ends will go up into the soil to feed the roots.
