Container potatoes

[duajones]

I found a 35 gal trash can a couple years ago. Cleaned it up and drilled drainage holes in it, with the thought of trying to grow potatoes in it. Ive read where you can start of with the seed potatoes with a small amount of soil, then as they grow, add more soil until you get close to the top. My question is, what would be the best soil choice, and what variety might some of you suggest to try using this method? And of course, have any of you tried this?
