We were using Epicure, an early potato. If your growing in pots the earlies to much better than the bigger Main Crop types as they are ready to harvest quicker and don't need as much space.
We filled the pots with Multi-Compost, added some leaf mould at the bottom and mixed in a few handfuls of chicken manure to the tubs... hopefully get soem nice, small, early potatoes last week of school term!
