You need to acquire the proper skills to do this.
1) Google is your friend!
2) If you want to grow sog and you only have one room, you need to start with a mommy first, should be easy.
3) Now you have your mommy, now your going to have to find a place for clones and learn how to clone.
4) Once you can successful take say 40 clones and have 30 or so live, repeatably........Now comes the tricky part.
5) Take your 40 clones and get rid of the mommy. I hate to say it, but do her in. You need the space.
6) Build up your sog setup, give it a test to make sure that the environment is good.
7) Now veg your clones for about a week or two.

If you can grow a good mommy, then by 2 weeks or so you'll have at least 2 good lower branches on each clone to clone again. Do this at about 2 weeks into flower.
9) Repeat.
You may have to adjust your timing here and there, but this is all doable.
Luck be with you!!
