The way I see it is, next time you smoke, don't necessarily smoke less, just put some length between your hits, don't do it one after another because that's some potent bud for sure. Take a hit or two, wait like 10-15 seconds and see how you're feeling. Then decide take another toke if you'd like :P Otherwise I'm not really sure about the sativa vs indica, sorry. But I do recommend growing your own, it's an amazing investment and his very well worth it in the end :P
