As peapod said, I also read that you should only underwater i.e. water in it saucer or whatever.
I have some I put outside in garden and some on kitchen windowsill. Both doing well. Ones outside planted same time much, much slower. Buts that ok planted too much anyway.
Have you tried "Lemon basil"....wow really lemon smell and taste. I want to try some "cinnamon basil", haven't got the seeds yet. Someone also told us "thai basil" tastes like that gum dentine, which is a cinnamon liquorish taste.
