Potatoes grown in Grass Clippings?

[self-contained]

I'd like to ask a stupid question. It's my first time growing potatoes, so bear with me!

If you have a container with the bottom third compost then piled up grass on top, where do the potatoes form? Do they just form in the compost layer, or in the grass as well? If they form in the grass as well, why isn't everyone doing this? I could have saved a lot of compost!!

Not a stupid question

Spuds grow in the grassy layers as well.
I put the grass on in stages. Once the spuds have grown 3 or 4 inches above the compost layer I put the first lot of grass on top so there's just the tops of the spuds showing. When they've grown up another 3 or 4 inches do it again. Repeat until bag is full.

I don't think that's a stupid question at all. Potatoes tubers grow on the roots of your potato plants. The idea is that the more soil you pile up along the stems, the more roots they produce. They are like tomatoes (being the same family). You want more roots because the more roots you have, the more potatoes you'll grow.

From this point on, whatever I say is speculation, so will appreciate more informed inputs.

I am guessing the moisture and darkness should be enough to get the stem to root. However, the material shouldn't be too dense or the roots/baby potatoes will have to struggle.

With grass clippings, other than the fact that they tend to clump and become slimy, you get all the other requirements. You have moisture retained, darkness, and some amount of warmth.

I decided to look up this process/material online, and this article seems to suggest grass clippings should work:
