Here is my view on this ... if you buy mids on the street your smoke will be ok. If you get seeds from the Mids and grow them with care, you will be very happy. It will definately be 10X better than what you bought. However, just b/c you grow a random generic seed with all the love in the world, it will only be as potent as its genetics. For example (sorry I am babbling) you take a healthy baby boy from 2 healthy parents that have a family tree full of healthy relatives. Now you take the baby boy that has great genes and put him in a 3rd wold country with just enough water and nutes to survive. You will now have something that could have been great but did not get the proper care and it went to shit. Now take a baby boy that has a family history of nothing but terrible medical problems ... everything from arthritis and bad vision to heart disease, cancer etc. You take that baby boy and you give him all the love and care ... but he doesn't survive. Why? His potential from the start was no good. No matter what you put in, you can only achieve the plants potential, no higher. Hope that wasn't too scary to read.
