🧴 BottleCore™ Irrigation – DIY Build Sheet

What is the BottleCore™?

The BottleCore™ is a vertical watering insert made from recycled plastic bottles. It sits at the center of a grow bag and delivers water evenly across the root zone, reducing evaporation and promoting deep, healthy root development.

💧 Why Use It?

• 🌿 Improves water distribution throughout the soil
• 🚱 Minimizes surface runoff and water waste
• ♻️ Built from recycled materials — zero cost
• 🔥 Ideal for hot or dry climates where water is precious

🧰 Materials Needed

• 2 to 3 standard plastic bottles (1–2 liters each)
• Sharp scissors or utility knife
• Heated nail or drill (to make holes)
• 🔧 Optional: bottle caps (to slow drainage)

🛠️ How to Build the BottleCore™

1. Cut off the bottoms of 2–3 clean plastic bottles.
2. Stack the bottles vertically, mouth-to-base, to form a continuous tube.
3. Drill or poke small holes along the sides of each bottle (avoid the very bottom).
4. Screw on the lowest bottle cap to slow flow — or leave slightly loose for faster drainage.
5. Insert the BottleCore™ vertically into your grow bag before adding soil, keeping the top neck above soil level.
6. To water, pour directly into the BottleCore™ — it distributes moisture deep through the root zone.

🌞 Best Practices

• ✅ Use in 15–20 gallon grow bags for ideal coverage
• 🌱 Fill with compost-rich, well-draining soil
• ☀️ Check water levels more often in hot weather
• 🧼 Clean each season to prevent algae or blockages
• 🧃 Consider using smaller bottles (1-liter or less) to conserve growing space
