Hate to rehash this old thread, but I had a question about growing out...
For the purpose of thickening the trunk, don't we want to encourage the roots to grow sideways instead of down?
My thinking is that a shallow longer grow bed is better than a small and deeper grow bed right?
Correct me if I'm wrong, but my current understanding is roots growing sideways encourage the trunk to thicken, and roots growing down encourage the trunk to elongate.
Am I wrong?
