well, if Saddad and us can grow them, you shouldn't have a problem
mind you, ours are undercover, we bought slips from T&M this year, we're hoping to keep some of the ptatoes to produce our own next year
some clever people on here bought organic ones and produced their own, we only managed to get one so had to buy
if you do a search for them at the tp of the page, there's loads of info on here ;D
