Incomplete resupination

[ArronOB]

Many of my orchids, when they flower, do not complete their resupination.

I think maybe this is because I usually bring my orchids inside when they flower, usually just as the buds are starting to open. Maybe the change of conditions or light direction interrupts or confuses the twisting process.

Has anyone investigated this ?

It doesn’t completely ruin the impact of the flowering, but they would look a lot nicer if all flowers were oriented naturally.

I have attached a couple of photos. Note some flowers have completed resupination, some have not. This is normal for me - maybe a ratio of 2 completed for every one not complete.
