Schwag would be anything grown comercial. Grown for volume not quality. Males/felmales dont matter, seed o well. They pack it into bricks and ship it cross boarders. By the time it gets to you who knows how good it will be. My last batch tased like crap but it was all in the cure, if it was cured at all!
What your calling dank/chronic Im guessing would be some of the homegrown stuff you got. Someone loved and cared for the plants. They were growing for quality not quantity. It was more fresh, not compressed, and tasted 1000% better. The highs are about the same. Just takes less of the good stuff.
Its all in the growing. I havent had good bud in years. I only smoked schwag because it was what I could afford. This year Im gowing. I took some schwag seeds and gave them some love. Im about 5 weeks away from some good shit! Its all in the love you show the plant.
