grow room set up

This is my first time growing and i want to grow in my spare bedroom I haven't done the measurements yet but it's a pretty good sized room and I wanted to use led lights for my autoflower otherwise I wanted to know how many plants can I put under a 1000w cfl bulb I want to use the whole room to grow 20 plants 3autos and 3 regulars. Autos: northern lights,white widow and think different so there's 4 plants of each of those strains which is 12 plants then for 'reg: purple haze(4plants), lemon kush(2plants), og kush(2 plants). I have one guy friend that's staying with me and he's use to growing regulars but he doesn't know how to do a ventilation system indoors since even though he's grown indoors he just says for me to let them grow basically I dont need a vent system so it's up to me to figure out a ventilation system but since I'm using lights that don't produce a lot of heat I don't think I'll be needing a exhaust fan so I need to know what fans to use and how to hook them up to each other with the ducting and carbon filter. Now to be more efficient with having a continuous grow I plan to first make seeds from each strain using the colloidal silver method and I might do that 2 maybe 3 times and then buy that strain again and do it again so then after I have enough seeds I'm going to finally start growing my weed, also can I get some step by step directions on making seeds I learned it a while ago but forgot to write it down so I need those steps again from start to seed harvest. So I need to know light set up for cfl or led lights and how many plants they can cover per wattage then I need to know my ventilation system from start to finish and what fans to use since my lights don't use a lot of heat and I plan on using a carbon filter. Thank you.

First off, slow down a bit, don't be in such a hurry and try breaking that into some paragraphs so it's easier to read.

Next read the sticky's at the top of the forums. Most if not all of the information you need to know is there. Some great "free" videos to watch also, was very helpful for me when I started.

1000 Watt CFL? - Think you mean HID as in MH/HPS bulbs. Again, the sticky's.

Lastly, cloning is easier than using colloidal silver, you have to be really careful where you spray it and know when to harvest the pollen sacks, if they burst you'll end up with more seeds than you bargained for.

Breath, Sticky's, and breath some more. It's not hard, but you will have to do allot of learning on your own.

Advice... Start small till you have some grows under your belt. Build a tent for the room. Easy to do with pvc and mylar/plastic/reflectix. For a grow that size, you don't want CFL and they do get hot anyway. LED you are looking at some serious investment.
