Materials You’ll Need 🛠️

Step-by-Step Guide to Making a 15-Day Drip Irrigation System 📏
Step 1: Prepare the Bottle
Rinse the bottle thoroughly to remove any residue. Remove the label for better visibility of water levels.
Step 2: Create the Drip Hole
- Heat the needle over a flame for easier puncturing (optional).
- Poke 1–2 tiny holes in the bottle cap for a slow, controlled drip.
- Test the drip rate — the water should drop slowly, not pour out.
Step 3: Position the Bottle
- Fill the bottle with water.
- Cap it tightly.
- Bury the bottle neck-down into the soil near the plant roots, leaving the base above the surface.
- Alternatively, position the bottle horizontally and poke holes along its length for multiple plants.
Step 4: Adjust for Longevity
To make the water last 15 days:
- Use larger bottles for bigger plants.
- Make smaller holes or fewer holes to slow the flow.
- Place bottles in shaded areas to reduce evaporation.
Pro Tips for Success 🌟
- For potted plants, use smaller bottles and fewer holes.
- Wrap bottles in foil to prevent algae growth.
- Add a pinch of Epsom salt for magnesium-rich water (beneficial for tomatoes and peppers).
Safety and Maintenance ⚠️
Expert Tip from Prof. Mark Benson: “Check the drip rate before leaving for an extended time. Too fast, and the bottle will empty early. Too slow, and plants may not get enough water.”
Clean bottles and caps after each use to prevent clogging. Replace if they become brittle from sun exposure.
Water Needs of Common Plants 🌿

| Peppers | 0.8–1 liter | 15L total |
| Cucumbers | 1.2 liters | 18L total |
| Potted herbs | 0.3–0.5 liters | 5–8L total |
