based on what ive read i think as long as you dont get seeds from mexican dirt weed or some oregano/cilantro shwag lol i think you can grow good bud. Some say they have grown bagseed and it came out horrible jus like the weed they got the seeds from, others say they have grown bagseed and it came out good! Better than the weed they got it from! So my opinion is i think if you got some decent regs,mids,christmas bud, zona/popcorn bud/recently heard it called beasters? Then it has the potential to grow very good quality bud. I think its what you make of it. If you give them the proper care and nutrients in excellent growing conditions without any males around i think you will have excellent bud or hopefully atleast better bud then you started with.
