Experiment LED vs windowsill

[Jacob Reitsma]

I did some simple experiment with chilli's to test the effect of difference in light source.

Two plants I grow from seed in my orchid box where it received 12 hours LED light (Citizen CLU048-1212 90CRI ) 16000lux measured with phone. Temp range is 14-25C°
And two plants I grow from seeds at the SW facing windowsill where they get full sun for about 6 hours when the weather is nice. Temp range is 21-23C°

Although I tried to make a 'bright shade' condition in my orchid box the plant were doing better than the ones who received bright light to full sun in my windowsill. Chilli's need full sun.
The plants from the box are much more dark in color, the are a bit further in development, they are more full/bigger leaves and they are even starting to develop flower knots, the windowsill plants don't.

Now I am confused about that maybe I give my orchids who are shadow plants to much light.
I was also wondering why the chilli's from my orchid box were getting so dark in colour.
