Depends on the size of your grow?? and are you city town or countryside?
Anything in a tent in a typical bedroom for example I wouldn't worry, unless you're venting directly out the window, which would look odd.
They used to fly over daily here, not as much thesedays due to cutbacks I reckon.
An annoyance for sure, used to sound like they were right on top of our house sometimes, but used to it now.
