Groundwater and white clover. (a) The state of the groundwater in each sample. Water vapor was observed in S100-1, S100-2, S200-1, and S200-2, but no groundwater was observed. Groundwater was seen to have accumulated in S400-1, S400-2, S600-1, and S600-2. (b) The white clover collected and measured 15 days after the start of the experiment.
