I know how to start sweet potato slips outside. When I lived in the South
(zone 7), that was OK, but now I live in zone 5. I started them outside
last year and didnt harvest as many as I would like, or as early as I hoped
..

Can I just start them in a warm well lighted room on a table, or do I need a
growing light?

Do I need to put fresh manure in the seed bed inside, like I needed to
outside?

I would like to get 100 to 150 slips. How many seed potatoes do I need to
realize that many?

Thanks for the help. Dwayne
