How to grow potatoes indoors
Buy seed potatoes that have a lot of eyes.
The eyes of potatoes are small spots on the skin; this is the part that germinates. One potato with 6 or 7 eyes can yield up to 2 lb (910 g) of potatoes.
Alternatively, buy potatoes and leave them near a window for a few days until they start sprouting eyes. Scrub each potato to remove the dirt.
