I'd like a way to easily (and cheaply) water my tomatos via a drip system. I built simple waterers using 2 and 3 liter bottles and wire hangers. My total cost outlay for this project was $1.16 for the drill bits.
1. Empty 2 or 3 liter bottles (rinse them before you start or this project gets kind of sticky in the middle)
2. Wire hangers
3. Box cutter or razor blade
4. Scissors sharp enough to cut plastic
5. Wire cutters
6. 1/16" Drill Bit
