What the group studied
The report asked how increasing ibuprofen concentrations in the water supply corresponded with the growth, harvest count, and bulb weight of French Breakfast Radishes. It describes 120 seeds divided equally among a water-only control and three treatment groups.
| Group | Starting allocation | Water treatment |
|---|---|---|
| Control | 30 seeds across two pots | Filtered water |
| 250 ppm | 30 seeds across two pots | 250 ppm ibuprofen solution |
| 500 ppm | 30 seeds across two pots | 500 ppm ibuprofen solution |
| 1,000 ppm | 30 seeds across two pots | 1,000 ppm ibuprofen solution |
The report describes a controlled environment of 65–70°F, 50% relative humidity, and 600 PPFD of light for 12 hours per day during the first seven days. On day seven, selected cells were moved into larger pots. The groups were then watered every three days for 28 days. At harvest, the leaves were removed, the bulbs were washed and weighed individually, and the group recorded counts, sums, and means in Microsoft Excel.
Reported measurements
These values are transcribed from the deposited report. They are presented as the group's reported measurements, not as a new statistical analysis.
| Group | Harvested radishes | Total bulb weight | Mean bulb weight |
|---|---|---|---|
| Control | 22 | 187.6 g | 8.53 g |
| 250 ppm | 20 | 184.3 g | 8.38 g |
| 500 ppm | 16 | 144.2 g | 6.55 g |
| 1,000 ppm | 6 | 39.7 g | 1.80 g |
The group reported decreasing harvest count, total bulb weight, and mean bulb weight as concentration increased. The report gives an ANOVA result as “F[4.915]; P=0.003,” but its notation does not provide enough detail for an independent reconstruction. I reproduce that result as reported rather than recalculate it or infer a stronger statistical or causal claim. The report also says visual inspection found no significant morphological differences and notes that histological sampling would be needed for a fuller morphology analysis.
Limitations recorded in the report
The report identifies several conditions that limit interpretation:
- boiling water was repeatedly poured onto the plants;
- too many radishes shared limited pot space;
- the study was small; and
- only six radishes survived to harvest in the 1,000 ppm group.
Within this classroom experiment, the observed pattern was narrower than the title alone might suggest. It establishes no safe concentration, clinical effect, agricultural recommendation, water-treatment standard, or environmental threshold.
