A friend of mine got a hold of a Skywalker OG Kush plant thats about 1 week into growing and he is giving it to me as a gift (awesome right?). I've looked on the internet and it sounds like some awesome shit that is really expensive typically. But I was wondering, how much bud will I get off an average matured plant? I've looked everywhere on the internet and here and can't find anything. Any pointers?
