The bines are trainable and much prefer to go vertical. If you train them horizontal you will get less harvest but generally you get a lot anyway so it may be fine.
My Cascade plant goes about 6' up a deer fence, than horizontal across the top. The plant is maybe 10-11 years old now. My harvest averages about 20 lb. before drying from a single plant.
so you get ~4 lbs per plant dry, looks like the industry standard (whatever that is) is about 2.8 tons per hectare which very roughly works out to about 10 lbs per plant.
I'd be happy with 2-3 lbs from each. What I'm really doing is planning ahead should there ever be a hot season.
Thanks again, the feedback is helpful.
