I assume that you have the same humidity variation as outside in your home, that you have the same temperature variation and that you have the same wind condition in your home as outside! do your plant dry up in the exact same time inside and outside and in that case, how did you do to verify that? I also have to assume that the absolut value of the humidity, temperature and wind spead is the same in your house as outside.
Otherwise your statement is incorrect!

No you have drastically changed all growing conditions for your plants and reduced the light quality to a spectral distribution way of the quality of the outdoor natural light...

I do not say that your orchid grow better outside I just say that your plant has had a mayor change in all growth parameters and you can not attribute that to your light source alone!
