I have a black truck. Any guess what kind it is? Its got knobby tires and dirty windows.
Sorry man, your question is just way to general to even give you a ballpark guess. Basically the only thing leaves will tell you are indica/sativa, especially without any pictures I mean come on do you think there's like 3 strains of bud? There's so many other things you could tell us about it that could narrow it down (smell, size, type of high, taste, etc) but the fact that its "mid grade" there's probably no real name for it.
Yes this goes along with the other unanswerables like "how much will I yield? What's the best this or that?
Sorry man.
