Farming Fresh
Using 1,500 plastic bottles to build a backyard aquaponics farm is a smart, eco-friendly way to grow fresh fish and water convolvulus (kangkong) together.
Start by cleaning and cutting the bottles to create grow beds, then arrange them vertically or in rows to save space. Connect the bottles with simple PVC pipes or hoses so water can circulate smoothly.
A small fish tank stocked with hardy fish like tilapia or catfish forms the heart of the system. Fish waste naturally enriches the water with nutrients, which is pumped through the bottle planters. The water convolvulus absorbs these nutrients, purifying the water before it returns to the fish tank. This creates a closed, sustainable cycle.
Ensure proper aeration, sunlight, and regular monitoring of water quality. With patience and simple maintenance, this recycled-bottle aquaponics system provides fresh vegetables, healthy fish, and an excellent example of sustainable backyard farming.
