No Joke!
I have grown this strain outdoors in Western Washington and turned several friends onto it also. I can only imagine how it grows indoors { thats next !} sent many a buddy home with drool on their chin after they wake up in my chair. I always warn them first this is no joke and take your time, it will hurt you! AMS rocks everything I've grown { 10 stains} are above and beyond. You can trust the quality!
