6 inches and 3 nodes sets minimum. All are quite large.
Great Hops for essentially any ale. Very fruity. Quite sure this is US Cascade with the higher alpha content than the Tassy Cascade.
Regular US testing puts these hops in the 10%AA range with 37% Cohumulone. Quite high for Cascade but its really good stuff!
We do quite well from this here and it has been used with success in large commercial batches of Harvest ale.
