When do bines stop growing?

[H22W]

Just curious how much longer into summer should I expect the main bine of my Centennials to keep growing?

Mine are second year and located in NJ. Currently the vigorous bines are lengthening several inches a day.

Thanks!

They usually don't stop growing until the summer solstice, then switch from vegetative to flowering shortly thereafter.

In my humble going-on-four-years of experience, hops stop growing shortly before they freeze to death...

Cheers!
