Want **fresh herbs year‑round** without a green thumb? A **5‑gallon aquaponics system** lets you grow basil, mint, and more in a tiny apartment corner—for **under $20** to start.  
This guide walks you through every step: sourcing parts, assembling the bucket, adding fish, and keeping the water balanced. By the end you’ll have a working mini‑farm that needs only a few minutes of care each week.  

## Build Your 5‑Gallon Aquaponics System  

You’ll need a clean **5‑gallon food‑grade bucket**, a small submersible pump (≈ 50 GPH), PVC pipe or flexible tubing, net pots, clay pebbles, and a couple of hardy fish (goldfish or guppies). Total cost stays below **$20** if you shop the hardware store aisle.  

First, drill a hole near the bucket’s bottom for the pump outlet and line the interior with a foam sheet to hold the net pots. Next, add a 2‑inch layer of clay pebbles as grow media, place the net pots, and run the tubing from the pump to the top so water trickles down through the pebbles.  

Keep the system stable with a simple cheat sheet: target **pH 6.8‑7.2**, feed fish a pinch of food daily, and top off evaporated water with dechlorinated tap water weekly. Follow this **hydroponic nutrient balance for small aquaponics** rule and your basil stays bright while mint stays green.  

Check water level every few days, clean the pump intake monthly, and harvest herbs as they grow. The fish waste supplies nutrients, so you rarely need extra fertilizer—just watch for any yellowing leaves and adjust feeding if needed.  

All it really takes is a bucket, a few herbs, a couple of fish, and that cheat sheet. Hit subscribe at [Your Blog Name] for more easy DIY projects, or share this post with a friend who’s ready to turn a neglected corner into a mini‑farm.
