dude, genetics have never been as important as you're going on about...you do have to have the potential within the plants, but you can give a schmuck who doesn't know fuck all the best genetics on the planet and they'll produce shit with it...and you can give me a mediocre seed, and i can bring out the best it can be...not saying im magic and can work miracles, but the environment has a much larger impact than you seem to think, as does the growers ability. perhaps he has been growing some strains that aren't quite as potent as others that are available, but all of them being bunk, every time? that's not genetics, it's some other variable
