As you can see, the bins are essentially full at this point. There are Papa Chonca vines pushing through a hole on the front, and a hole between boards on the left rear. I have removed several boards on the bottom and middle of each bin to view the root structure. Papa Chonca has a very dense, fibrous root structure compared to CIP396286-7, but both have stems/roots present from bottom to top of the bin at this point. It is nice to see that they each are still pushing stems upward from the bottom as well.
I have since drilled approximately 8-10 1/2" holes on the front and several on the outsides of the bins, to see if any of the stems/stolons/roots will find their way outside the bins, like Papa Chonca has done in two places.
