The document describes tests conducted on a hydroponic system to grow vegetables. It discusses 4 phases of testing: 1) Estimating nutrient and water needs, finding the system holds around 82L. Refills will occur below 40L. 2) Running the system for 6 days showed no stagnation or mosquito issues. 3) Initial seedling batches failed due to fungus/too much water. Leca was added, improving subsequent batches. 4) A long-term test saw algae bloom and pest problems. Countermeasures like cleaning and adding more plants were implemented.
