Green seeds are generally more on the "premature" side - they take a bit longer to germinate from my experience. (granted it's not much, a pro will come in here and clean things up I'm sure.)

I've definitely grown them into healthy plants, though!

Btw, a half foot would be 6 inches and it would make the plant's life quite difficult

Don't be afraid to ask anything here, I apologize for sandman and anything else he might say in advance.

LOL, jk.

But seriously.
