Newbie hydrogrow.. Need some help and advice please!

Hey all,

I'm gonna attempt my first grow. I just recently bought a cool cab from sunlight sheds and just ordered my seeds from attitude a few days ago. Im so excited to start this process, but i am also a bit nervous.

Here's my list of stuff:
Cool Cab by sunlight shed's. here's the link to check out all that comes with it. I also purchased the CO2 boost with it.

Cool Cab

Here is my list of seed strains i purchased:
10 Seedsman Big Bang Feminized
5 Master Kush Feminized
5 KillaWatt Feminized
1 White Widow Feminized
1 Durban Poison Feminized
1 Northern Lights Feminized

I am going for the highest yield possible but of still very high quality buds. My main question is what method to use when growing? and how many plants do you think I could actually grow in the Hydroflora system the cool can comes with? and also what seeds strains do u think i should grow first? since it is my first grow, and which will give me the most success using in my cab?
I'm sorry i am asking for so much, but there are so many great and helpful ppl on this site, i figured i would just ask, because i really want to do the best i can. I don't know if i should just do a standard hydro grow or if i should use the SOG or SCROG method. I was actually leaning more towards the SCROG. Please let me know if you have any advice or comments. Thanks so much. It is very much appreciated.

Have you ever grown indoors before?

No i haven't. This will be my first ever. Thats why I am asking for so much advice. Any would help.

I've done loads of research and read many other forums and books, but i just wanted to see what some other hydro growers thought i should do. Just want to make my first time the best as possible. I know it wont be perfect and things will go wrong but i want to try to prevent that as much as possible. But i know i will only learn from my mistakes no matter what happens. Thanks so much
