Well, popcorn is normally the buds from the bottom of the plant that are light and fluffy, because they get less sunlight, as opposed to the ones from the top that are normally dense, because they have more light and use it to grow thicker and denser.
"Dro" means it was grown hydrophonically, and because Hydrophonics normally produces a more potent plant, because of the ability to provide it with what it needs quicker, and it doesn't need to put energy into growing roots, all of it's energy go's to growing big, or, when vegging, growing potent, so "Dro", is normally equated to "Dank". The problem is, there can be some pretty shitty hydro'd weed, so by sticking the term "Dro" on the front of it, it's price automatically jumps.
