Having got my Lemon tree and Calamondim well on their way I thought I'd give the Kaffir lime a go, and have successfully germinated 5 seeds.

They seem to be growing incredibly slowly on my windowsill getting moderate light and I'm wondering wether I can speed them up a touch with fert or even more sun.

Has anyone had any experience with these or should I just be patient?

Also while germinating my citrus seeds (of different types) I've noticed some hold onto their seed pod for quite a while is this normal?
