Went back and re read your post, I do not know what PPP is, but for indoor yields, the Northern/bigbud will be a good yielder, but not as potent as say the WW, and the WW can be a high yielder in door, but can take more time. The WW can do really good out side because they can really reach there full potential and produce some amazing harvests. I don't know much about the Kush, maybe somebody else can answer.
