Spice pack seeds don't always grow right
I've tried them a few times
They certainly sprout but sometimes don't get taller than about an inch
I've grown "proper" seeds too
They need a bit of sun, but do ok outside in a pot, during summer
Cooler months may need a window ledge pot inside
The biggest problem, I had, was staggering the crop
Even when weeks sown apart, they all seemed to catch up with each other
Then they go to seed
Having said that, the green seeds are really nice
