You know how cops are always busting people with houses full of marijuana plants? What if you did all of that but with potatoes instead of marijuana? What if you had an entire house full of grow lights and potato plants in buckets and then every inch of lawn on your property had potatoes and not a single blade of grass?
Would anyone care? Would the cops come along and put a stop to it? If not, how many more potatoes would you have to grow before something like that happened?
There is no limit to the potatoes you can grow. The only limit is your imagination.
If you live in a place where cultivating cannabis is prohibited, and your power usage spikes, you may be placed under surveillance.
If you have an HOA or city ordinances about the condition of your yard you might get a slap on the wrist if your potato farm is unsightly. Otherwise, as not a lawyer, grow on.
