not only will the yeild be less but your potency will be less, less dense buds, u need to wait untill atleast cloudy/clear trich's if u want it to be a good smoke/high. You grow what u buy, i have dope bagseeds i use that produce great results. You dont need to pay out for expensive genetics, u need to find a strain and breeder you like. bagseed is always fun becuase u never know what ur gonna get, but u know what the bud is going to be like.
