Raised Bed Hugelkultur Height

I’m working on building some raised beds with pallets like DirtPatchHeaven’s hotbeds but don’t really need the heat and was wondering if anyone has thoughts on the benefits of keeping the full height of the pallet versus cutting the pallet in half and having approximately 20-24” high beds filled like a hugelkultur bed that’s just boxed in?

Personally, I prefer a 30" high raised bed as that's easiest on my back. It also gives me lots of room for hugel wood at the bottom, but still a good amount of soil so the plant roots have lots of room.

I find the soil will really sink the first few years after building, but by building higher, there's still enough soil depth at the end of the growing season for the plants to cope.

Mine are 2ft high.  Like Jay, I find there is less bending.  I normally fill the bottom 1/2 with spoiled hay and bedding from the livestock.  

The exact composition depends upon what has been planted.  Potatoes, for example, tend to have more straw from the bedding.
