Sure, why not......but......a trellis.....I tried that with the 6 HBSS I grew a few months back, didn't matter, the damsels still produced a thick, high jungle that would be right a home on the Discovery Channel surviving in the wild shows. Naked and Afraid.....
IMO if you want to grow an Ultimate to it's ultimate potential.....space, space and space, in all directions. all other techniques are just sobs if it's the ultimate yield that's the target.
