Start at the top if you are going to get a star strain then go all out for the best blueberry mk ultra and the king of all strains jack herer.Some of these strains can be a little expensive but in the long run well worth it.Something to be going on with that is not that expensive i would go for ak47 or afganica both have realy good track records when it come's to yeild.Jackherer can be a little tricky even for the most educated grower's.
