An individual converted a spare 42-unit server rack cabinet into a flood-and-drain hydroponic system in early 2026 to grow lettuce and herbs, successfully producing multiple batches despite the unconventional setup and two minor water leaks. The author acknowledged the approach was impractical compared to traditional growing methods but found the project educational and produced usable crops.
