Is there a difference between in-door vs out-door grown?

"I know in South Africa, this stuff is probably grown outdoors in the sun. Is there a reason to favor one over the other?"

Durban Poison is a hardy strain and can be grown in either environment. If grown properly and allowed to reach full maturity, there should not be a significant difference in medicinal properties. This topic, in general though, is the subject of much debate.
