It's often said that hops grow so quickly you can almost watch them. For a while now I've been trying to get some time lapse footage of exactly this just to make it clear just how fast they are:
This particular example doesn't really show them growing in length but it does clearly show how they swing around looking for something to wind themselves around so they can grow upwards. If I weren't trying to get them to grow up mine twine in a helix pattern it most likely would have found it. Perhaps this is a sign that my helix is too squashed and I should try to make it more vertical next time. Might help with the training of the bines.
