You want a strain that stacks nodes like crazy you might want to try Papaya from Nirvana. Not sure if it's just the genetics, or environment (probably both) but I've never had a plant stack nodes like this in my life. It stacked so dense for the first 4 weeks that the plant was producing more leaves and growth shoots than it could make room for. I actually had to force it to stretch so it wouldn't choke on its own vegetative growth.
