In spring, I put a few sprouting potatoes in the compost, waited a few month and since July or so I have a huge bucket of homegrown potatoes that I have problems to use up. So very easy food source. Can recommend. There were a few pill bugs/ potato bugs who love the taste of the plants, but their damage had not much effect on the harvest in the end.
I believe I read that it helps with lung development when the fetus is swimming in the water in the womb or something like that. But otherwise not really useful.
