fun to see all the things we don't cos we live on a different timescale. couple of interesting things I noted;
you can see the leaves all raise up and get perky when the lights come on after the short night cycle (8-11am) , during the night they kind of look like they fall down a bit like the plant is chilling out a bit and having a rest. light comes on and they rise again, time for action!
other is how they wiggle along, to me this looks like the plant trying to tune itself to grow at the light. solar panels thesedays do the same thing, a control circuit moves them around to follow the sun. the plants has a more basic method, it wiggle one way till the Photosynth on one leave is more than the other, then the situation reverses, so they wiggle along, but always tracking towards the light. the plant overshoots a bit each time, its a basic control system but quite sufficient!
I imagine in natural conditions we'd see them track the sun through the day.
