It’s inexpensive, scalable, and requires minimal upkeep once established. This setup focuses on stability and simplicity, using a large water reservoir, basic aeration, and passive root access to nutrients. --- ## **Why This System Works** At its core, this method relies on a few key principles: - A **large water volume** helps stabilize nutrients and pH - **Aeration** prevents stagnation and supports root health - **Simple circulation** keeps the system from becoming stagnant - **Direct root access** reduces the need for complex feeding systems Once the plants are established, the system largely runs itself. --- ## **What You’ll Need** For each hydroponic tank: - Large **Rubbermaid tote** (serves as the reservoir) - **6 grow baskets** or lipped net pots - **Air stone** - **Aquarium air pump** - **Small water pump** (for circulation) - Tubing for air and water Optional: - Growing medium (puffed rock, clay pellets, or coconut husk) - Drip emitters (not necessary once roots are established) --- ## **Step-by-Step Setup** ### **1\. Prepare the Reservoir** Start with a large Rubbermaid tote. This will act as your nutrient basin. Cut evenly spaced holes in the lid so your grow baskets can sit inside securely without falling through. These baskets will hold your plants above the water. --- ### **2\. Install Aeration** Drill a small hole in the side of the container for the air hose. Feed it through and attach it to the air stone, placing the stone at the bottom of the reservoir. The air stone continuously oxygenates the water, which is critical for healthy root development. --- ### **3\. Add Water Circulation** On the opposite side, cut a hole for the water pump line and power cord. Run the tubing so water is pulled from the reservoir and returned above the surface, allowing it to circulate. This prevents stagnation and keeps nutrients evenly distributed. --- ![Chard leaves](https://storage.ghost.io/c/1d/fa/1dfa0703-59cd-42c7-a4f8-b16e218c2d7c/content/images/2026/04/mondgesicht-salad-7844746.jpg) Image by Lars Beulke from Pixabay ### **4\. Insert Grow Baskets** Place your grow baskets into the lid openings. You can use a growing medium like clay pellets or coconut husk to support seedlings early on. However, once the roots extend into the water, the medium becomes largely unnecessary. --- ## **How It Functions** This system is essentially a hybrid between deep water culture and a basic recirculating system. - The **large water reservoir** buffers against nutrient swings - The **air stone** keeps roots oxygenated - The **water pump** maintains circulation - The **plants eventually feed directly from the water** Once roots reach the reservoir, the system becomes highly efficient with minimal intervention required. --- ## **Scaling the System** If you want to expand: - Use a **larger air pump** with multiple hoses to supply several tanks - Run **separate water pumps per tank** to reduce failure points - Keep systems **modular** to prevent cross-contamination or nutrient issues While it’s possible to link multiple tanks together, running independent systems tends to be more reliable and easier to manage. ![Urban Vegetable Cultivation Vertical Hydroponics](https://storage.ghost.io/c/1d/fa/1dfa0703-59cd-42c7-a4f8-b16e218c2d7c/content/images/2026/04/spencerwing-aquaculture-5990462.jpg) Urban Vegetable Cultivation - Image by Spencer Wing from Pixabay --- ## **Maintenance and Tips** - Check water levels regularly - Monitor nutrient concentration and pH - Clean pumps and air stones periodically - Watch for root health (white, not slimy or discolored) Once dialed in, this system requires very little daily attention. --- ![Spinach](https://storage.ghost.io/c/1d/fa/1dfa0703-59cd-42c7-a4f8-b16e218c2d7c/content/images/2026/04/pexels-magda-ehlers-pexels-28797268.jpg) Spinach - Photo by Magda Ehlers on Pexels ## **Final Thoughts** This basin-style hydroponic setup is one of the simplest ways to grow chard indoors. It avoids unnecessary complexity while still delivering consistent results. You don’t need advanced equipment or a large investment. All you need is a stable reservoir, basic aeration, and a simple circulation loop. Once established, the system becomes largely self-sustaining, making it ideal for anyone looking to grow fresh greens with minimal effort. ![Spinach Leaf](https://storage.ghost.io/c/1d/fa/1dfa0703-59cd-42c7-a4f8-b16e218c2d7c/content/images/2026/04/couleur-spinach-3463248.jpg) Photo by Couleur on Pixabay
