The runners are the shoots with leaves on, if you are going to gerow them in a bucket, bin, or a sack, put a few inches of dirt in the bottom. Place the potato on the surface with shoots/runners facing up & cover with a few more inches of dirt, once the shoots apear around 3-4 inches, cover with more dirt. Do this until the container is full, then wait until after flowering & the leaves & stems start to wither, at this stage the potatoes should be ready to harvest. Hope that helps? I grow them that way all the time & use normal potatoes, not the seed type.
