I was able to listen to this episode yesterday and enjoyed it.
Once they finally got past the negative aspects of it (I felt like they over-emphasized that hugelkultur isn't right in every scenario) there was a lot of great information. Talking about situating the beds against the prevailing winds was great, and the concept of increasing solar exposure by making the beds face the sun, was great. I also was surprised that my favorite part of the podcast was the talk about broadcasting seeds.
Lots of great food for thought in this podcast. One of his best.
