Sorry Pal, there's just not any GOOD "shade" cannabis that I'm aware of. However, I would suggest that you do a little more research.
Contact some seed banks and tell them what you are looking for. You just might be surprised at the response. Yes, some will blow you off with, "we only sell souvenirs", and "we don't discuss such things". But keep digging, someone has the answer. This my friend is part of the growing adventure. Good luck & good grow.......BB
