Growing Potatoes in a bucket

There seems to be alot of interest in growing potatoes in a bucket. I can only talk about my ongoing success, because my work with potatoes is in a progressive state. From what I have gathered so far, the most important thing to do is acquire very good seed potatoes. A lot of literature states that you can use store bought potatoes that have the shoots on them, but they are not recommended. I personally used the advice of those that suggest purchasing the seed potatoes because they have a better success rate. I must admit getting these potatoes to grow has made me feel like a pro, only because I have grown something and it was green. Nevertheless, the seed potatoes are easy to grow in a bucket if you follow a few simple steps. What I did was add a layer of enriched compost and highly organic soil at the base of the bucket. As the shoots start to grow up ward towards the sun, all you need to do is add soil to until the highest leaf is just barely covered and continue until the shoots have reached out of the bucket. I have two experimental buckets; One that I planted in one bucket and the Second, I added an additional bucket around the top of the leaves to see if I can cultivate potatoes on a second level. As per instructions, the potatoes are done growing when the leaves have died back. You can harvest earlier but that would mean smaller potatoes. Its going to be interesting to see how these guys look in the fall. As for now I am relishing in all the green that is shooting from out of the buckets
