Option 2

Materials

• One 2-liter soda bottle
• One bottle cap
• Tool Box
• Wicking material-fabric interfacing or cotton string
• Water, soil and plants

Step 1 – Remove label from the 2-liter bottle. On bottle #1, cut 2 cm below shoulder to produce component "A," a shallow funnel top and "C" a deep reservoir.

Step 2 – Poke or drill a 1 cm hole in bottle cap.

Step 3 – Cut Bottle #2, 1 cm below hip to produce component "B" a deep funnel unit with hip taper.

Step 4 – Fill reservoir with water. Add soil and plants to top chamber. To be effective, the wick should run up into soil, not be plastered along a side of the bottle. For better drainage, place a layer of gravel, sand or vermiculite in the bottom of the soil unit.
