Is this a spike on this Phal?

I do give credit to all PhDs personnel, but to say that one PhD is more knowledgeable than someone growing plants for numerous years. Sometimes experience defeat PhDs lol in my opinions. U can obtain PhD at age 28, does not means this person will have 30years of experience in term of what he/she studied. Hope you all got my points.

No, totally can’t get your points. This research is not showing the authors can grow phals in different conditions. The experiment is to figure out how the temperature and light affect phals. If you don’t put the phals in chambers to make the temperature or the light to be the only variable parameter, how to confirm what affect the phals?

And for someone who always emphasizes that he has grown orchids for XX years, he may know how to grow them in his environment, but doesn’t mean that he understands how it worked.

Every windowsill/indoors environment is unique and that environment changes constantly - as people walk by, as aircons flip on, as seasons change, watering, fertilising and mix compositions.....you get the idea.
Some phals for example bloom regularly in my cultural conditions. For those that don't, I am conducting my own experiment by placing them outdoors for Summer/Fall - with the hope that the change in average temperatures ( as recommended by the Phd types ) trigger spike development.

Yes, we’ve got a very different environment from greenhouse. But some results, like the influences of temperature to phals won’t change its roll in phals’ growing and flowering. That’s why you’d try your experiment, isn’t it?
