Frisian dew starting under houselamps

The second week I was away. at my mothers for easter, Plant under ordinary supermarketlamps with a timer, lamps off between 10 in the evening and five in the morning, and off between 10 in the morning untill 2 in the afternoon when the sun may shine through the window and both sun AND ledlights at the same time would be exaggerated. My girlfriend inspected and showed the plant with the camera on the phone.
