Not sure about the towers, and since I don't know where you're located I can't suggest a place for you to buy slips. Click on Organic Businesses on the left of this page and look to see if there's an organic nursery in your area. I would call them and find out if they carry them. In Dallas, I would check with Redenta's or NorthHaven nurseries.
sweet potato slips were delivered last week (puerto ricans)... i have started a tower 24"dia 6x6 welded wire cage x 5' tall...ringed bottom 12" with newspaper, filled with leafy compost and soil...4 slips, 1 died and was replaced with a "spare" (i have planted the extra slips in the ground in the traditional fashion for comparison)
when these grow taller, i will add compost and more soil, lining cage with newspaper as it grows...
Dallas is supposed to be good sweet potato country, my section of Oak Cliff is alkaline clay and brittle limestone, so if the tower works i will be glad....much easier than digging new garden area.
I know this is an old topic, (hey, I'm just returning after a long absence!) but you can buy really nice sweet potato slips from Steele Plant Company sweetpotatoplant.com I haven't planted mine in a tower, just in raised beds, but they are doing well.
