A)
Mids/schwag is nothing but good pot that's been mishandled. Harvested early/late, untrimmed, improperly cured, vacuum packed, kept in some basement awaiting transport, exposed to fluctuating tempuratures and humidity, then somewhere down the line of these atrocious conditions it makes its way to your dealer. Bad weed is nothing but weed that's been mishandled to allow for greater/quicker production.
B)
For the most part, yes, but like I said above those little seeds often endure their own personal hell on their way to you. Some certainly will sprout, but expect the majority to be dormant.
C)
All seeds contain the genetics for being either male or female. The more ideal the growing conditions, the more likely you are to have females. Also, techniques like feminization and
ethylene gas exposure have been proven to make the seeds more likely to be female.
