Thank you for your support Kenny and Beppe
All the plants I have bought already grown have died, that's why I decided to try my luck with seeds this time. At least they won't have to go trough the trauma of being snatched from their comfortable hothouse to a truck, to a shop, and then to my apartment and too much water, or not enough, or whatever.
I feel I actually have a better chance with seeds, if I don't do too many stupid things.
Well, we'll see...
