I just want to add that using seeds from grocery store produce may not produce the vegetables that you are hoping for. Many grocery store vegetables are hybrid that do not breed true (they don't produce the same vegetable that you purchased). They may produce a vegetable that is the same or better, but more likely will produce one that is less desirable. To get exactly the vegetables that you want it is best to buy seeds from a reputable supplier or get them from an experienced gardener/farmer.
