Had the tent on for this weekends rain. I took it off this morning the foot is nicely still dry and it's airing out.
I am also including this picture of the Hercules foot for note and comparison. I think I noticed that the Hercules is going to put out a new root. Looks like its sprouting out of the foot. I'll be monitoring the Samson for something similar to happen. I've also noticed that the roots seem to also develop "trunks" around the top part where they go into the ground...
