New grower, have a few questions:

Hey, I just celebrated my 1 year and a half anniversary of starting smoking the other day, and now I realized that since I enjoy smoking so much Id probably enjoy it more if I was smoking bud that I put my own hard work and effort into. In my back yard I have a completely fenced in yard with a tool shed, and a 6ft tall fenced in area around the shed thats gated off so you cant see into it. I have like 19 random seeds from bud that I've bought off homies, I would always save the seeds off bud if it was good bud. Now its starting to warm up a little bit, and I figure once its spring I might as well germinate and put these seeds to grow. Just wondering what kind of soil I should buy, how far apart I should place the seeds, and any beginners tips you can give me to help me get a good harvest. Some of these seeds are guaranteed white widow, another one is purple haze, i have some skunk #1, some type of high sativa bud, and my personal favorite some early misty. I have roughly 4 seeds of each, and I guess I'll have a little neopolitan mix of buds growing in my backyard if I do it right. THanks to anyone who answers my questions!
