Very cool, It is great to see someone experimenting with sub-surface irrigation. If you have to irrigate, irrigate subsurface. My only suggestion is that your thyme might fair better in poor soil. It will produce more essential oils when grown in poor soil like most Mediterranean herbs. Hugelkulture I think -- and this is just the ramblings of a crazy man -- would be better suited to herbs like basil, chives, and mint. Very cool vertical Permaculture.
