You can fruit them in smaller pots, but they will take longer, and the bunches will be smaller. I personally wouldn't spend any money on any kind of special container. A good potting mix, adequate sunlight, and careful attention to water fertilizer (typically more water and less fertilizer than is required for growing in the ground) is more likely to result in a harvestable yield than a specific special container in my opinion. To have any serious shot at fruit, I wouldn't go smaller than 10gal, but would still recommend 20-25gal. Just a standard plastic pot works fine, or even a rubbermaid type bin with holes drilled in the bottom.
