I have grown sweet potatoes in half 55 gallon drums and they grow well, except in my garden, they'll take over a year to produce good sized potatoes. Sweet potatoes are strong growers and don't need to be hilled like regular potatoes. Soil should be on the loose side with considerable compost. Grow bags should also be OK, I think I've seen them used on Youtube.
