I've been tasked with setting up a small, semi-automated hydroponic system in the unused basement of our community center to grow leafy greens for our weekly soup kitchen, aiming for about 20 pounds of produce per month. I have a very tight budget of $300 for the initial setup, excluding ongoing nutrient costs, and I need to keep the electrical draw minimal as we're sharing the circuit with the building's aging boiler. I salvaged some PVC pipes and a basic submersible pump, but I'm struggling to design a reliable, low-maintenance drip or NFT system that won't clog with our hard water and can be managed by different volunteers with zero hydroponic experience. The center director wants a pilot batch ready in six weeks, which feels impossible with my current cycle of leaks and inconsistent flow.

Plan a compact drip NFT hybrid: use 2 shallow PVC trough channels fed by a small low‑watt pump and timer to drip to 6–8 emitters, with water returning to a shared reservoir. Add a 100 μm inline filter and a manual flow valve. Build modular, leak‑tested sections; prepare a simple SOP for volunteers; run a 2‑week pilot before scaling. Under $300.
