hugelkultur in Pacific NW greenhouse?

I'm a permie neophyte, so bear with me!

I live in the PacNW but have a greenhouse with (I think) adequate drainage. Am I a good candidate for hugelcultur? The hardpan clay appears to be about 18 inches below the soil, so would I have to excavate into that? Also, in a 260 square ft plot, about how many hugels are needed? If I'm going to be growing vegetables in rows, can I get 2 rows per hugel? Thanks so much for helping out a newbie! Cheers,

Hugelkultur is from what i understand is burying wood and often times it is done in sporadic planting and even a seed mixture. I planted in rows and i hae seen other do it. In my greenhouse im about to build i plan on using soil mix and some hugel style methods as well. Also wood breaking down gets spongy and sucks up water. Save the clay for cob for a rocket mass heater for greenhouse

Instead of sqft a LxW would be better.
So if it is 24ftx10 you could fit two hugelkultur
24ftx4.5ft +1ft walkway +24ftx4.5ft hugelkulture

On each hugelkultur you have left side, top, right side so at least 3 "rows" per hugelkulture.
depending on how high you build the hugelkulture you could get 2 or more rows per side

You could dig the walkway two feet deep if you are worried about drainage/clay.
But I would only do that if after you built the hugelkultur you ended up with drainage problem

Hopefully this helps

I was thinking of doing this in a geodisic greenhouse.
One mound in a circle against the side and a mound in the middle.

That's exactly what I was planning on doing!! (The RMH would be in the house, tho.) That would combine my two favorite things that I've discovered on permies.

One issue that I was worried about with my initial question is that I have read about Symphylans being a hard to control pest in the Pac NW and I'm wondering if a hugelkultur will exacerbate that problem, or if it won't really affect it at all? Any opinions? Thanks!
