I've been told that hops will twine in different directions as they climb
upwards according to which hemispehere in which they grow.

Oh.. I thought it was , the way water swirls round as it reaches the
plughole.

I'm in the Southern Hemisphere and my hops twine clockwise around supports.
Every single one of my stems is growing clockwise with not one counter
clockwise grower.

Has anyone in the Northern Hemisphere noticed which way hops twine where
they live?

No, but I'll go out and look at mine in a minute. Then I'll have to
check the plughole..

Hops climb from right to left.

Plughole, water goes down anticlockwise.

The direction that climbers twine is controlled by their genetics.
Some, e.g. hops, climb from right to left, but the majority, e.g.
beans and bindweed, climb from left to right*. Nothing to do with
which hemisphere they grow in, or the direction of the sun's travel
across the sky, as many seem to think.

The way water spirals on going down the plughole has nothing to do
with the hemisphere it's in, either, but everything to do with eddies
set up in the basin or bath when the plug is pulled out, and/or subtle
differences in plughole design etc.
