Of the twine that is. Reason I ask is I was checking in on my plants and one bine has reached the top eye bolt to which the twine is running through, so I climbed up to look at the top about 12' and there is no bud coming off the end. I just wonder if a bird ate it or it somehow knew there was nothing to continue grabbing onto and it just terminated itself. I strung more twine horizontally from that eye bolt in hopes that once it hit the top I could then train it horizontally to get more growth, there's two other bines on that same piece of twine close behind so if that ones lost there's the other two, plus a whole other plant. Just wondered if hops actually know when they hit the top otherwise how do u stop them from continuing to grow. Oh These are first year cascades in 5 gal pots.
