This is a very unexpected finding.

"Thus, our results show that pea seedlings develop an association that
facilitates growth towards the light based on the occurrence of a neutral
cue. This learned behaviour prevails over innate positive tropism to light,
which is thought to be the major determinant of growth direction in plants.
In both experiments, the ability of seedlings to anticipate both the
imminent arrival of light ("when") and its direction ("where") based on the
presence and position of the fan indicates that plants are able to encode
both temporal and spatial information and modify their behaviour under the
control of environmental cues."
