Yea its possible to grow seeds found in ur bag of weed. People call it bag seeds. Half the people on this site I feel are growing bag seed. I found a great way to germinate seeds are to throw them in a glass of tap water and let them site for a day or two. I did that with 18 out of 20 seeds popping from bag seed. I only kept 5 plants due to lack of grow room saddly. They all turned out to be female go figure. I only planted 10 of the 18 seeds tho and I just kept getting rid of them one plant at a time. Heartbreaking really
