My goal is a minimum of 6" after being compacted, the crushed pseudostems also works perfectly.
It seems a little odd that the climate makes that much of a difference, but that explains quite a bit about the differences with water and nutrients and even why you guys seemed satisfied with 5'-10' feeder roots.

At least now you know you had a great idea, just the wrong climate.

Thanks for the info, Mitchel.
