How Am I Doing?

Hey everybody, I'm growing for my first time and I got a garden going and I got around 30 seeds and I dug 4 rows of 4 holes and have 16 holes total and they are about a foot deep and about foot wide, filled with Miracle Grow. I've germinated the seeds and everything and planted them about an inch deep. What I did was plant roughly around 2 seeds a hole and its been a week already and some are sprouting! I'm doing this outdoors and they are growing in an open area where sunlight has no problem hitting the plants and I've been watering them everyday. Could somebody give me an estimate of how you think this whole operation will go? Like if I'm giving it enough care? How much an outdoor plant gives off? Lets say most of them sprout and I get about 10 female plants, anybody give me an average of how much bud would get produced. Also if this helps I'm growing on the East Coast in Mass. Thanks for all help and also, after about 3 weeks should I replace the soil?

Thanks In Advance.

Well if its outdoor id just let mother nature take its course. Mass damn must get a bit cold! I was in boston for a while. Sounds to me you are on the right path. I keep hearing miracle grow is bad miracle grow this and that but mygirls (riu member) uses it and grows fucking ape shit. King kalidas type buds.
