Kevin, You don’t need sun, just daylight. To break dormancy, maintain a warm temperature of around 70°F (21°C) in a dark area to encourage sprouting. Once you see sprouts, move them to a cooler location with some indirect light at around 50°F (10°C) for healthy green sprouts. So, prioritize the temperature and light exposure, whether it’s natural or artificial, for successful potato chitting.

Sandra, Bury the sprout as best as you can. You can even dig a trench and lay the sprout horizontal if it is very long.

Kathy, In the article, I suggested breaking dormancy in a dark area and then introducing the potatoes to light as the sprouts develop so they green up. However, either way will work ok. One of the greatest things about the internet is everyone can share his or her experiences and you get to experiment to find out what works for you.
