Complete original fictional garden card, not local soil data. In one supplied trial, samples P and Q use the same described spoon size, each receives20 mL water, and the same filter setup and2-minute collection window are used. The labelled collected-water entries are P4 mL and Q9 mL. A visitor asks which soil grows the tallest tomatoes. No plant-growth, soil-quality, organism-count or drinking-water entries exist; no real child conducted this trial.
