**please help me finish grow setup**

so i recently joined riu but viewed a while before guess like most did, but anyway love the site and hi to all

room for all things(my bedroom): 10 x 12 one window( with small a/c unit 4.5amp 550watts )
flower room: 4 x 4 x 6 (ply) ** 6" exhaust hole, 4" intake hole
veg room: closet in the room 2 x 5 x 5.5 ** 4" exhaust hole 3" intake hole
clone box: 17" x 18" x 27.5"
temps in the room low of 70-72(house temp, nothing on) and high of 79(with 52" on and 60 outside)
*all grow boxes with mylar*

plans: 9-12 in flower( month veg ) 1-2 mothers( if possible ) of a strain i find i like, clones and constant veg and create a cycle eventually...

things i have: 400w mps from htg( used for a year, 3yr old ) euro cool reflector 6"
2 growbright 6" inline fans (160cfm)
2 6" x 8' semi rigid ducting
1 4" x 8' semi rigid ducting
flower:
things i want: 600w digi ballast** http://www.ebay.com/itm/iPower-600w...t=LH_DefaultDomain_0&var=&hash=item23240e4109 or http://www.ebay.com/itm/160801640900?var=460071857577 if i go with htg i can reuse the 6" cool reflect unless i need a 8"???

8" fan ** http://www.ebay.com/itm/200829211080 or http://www.ebay.com/itm/270931081929?var=570063786085??? so being the room is kinda hot i wanted to go with a 8" fan(700ish cfm) exhausting out the window beside the a/c to try and cool the grow mostly and the room too any thoughts

8" carbon filter?? was thinking phresh 18x24 ( looking to grow some stinky lol )

exhaust side: filter-fan-hood-out grow box roughly 10ft to the window??? intake side: 4" duct(8') any screen or filter needed ? or hole bigger?

veg:

2-3 4' t8's
6" inline w/ 4" duct maybe 6'

2 6" osc fans in both

sorry for the sloppy post guys tried to get it all out before i forgot lol

my question summary kinda
1. 8" fan too much?
2. use 8" fan and get htg ballast and use 6" cool hood with reducers or get the other with 8" cool tube( if first one WONT work)
3. 8" phresh filter good enough? http://www.ebay.com/itm/120839016431
4. veg room ok to reduce the fan to 4" duct or just cut hole bigger and run 6"?
5. 6" osc fans ok?
6. is flexible ducting ok or should i use all semi rigid?http://www.ebay.com/itm/120932582252?var=420081690290 was going to use this
hole in flower room is 6" but can be cut for 8" if thats the route

thanks soo much guys in advance, soo looking forward to getting back at this

IMO 8" fan is to much for ur space unless u got a speed controller to dim it down some.. id just go with a 6" fan n filter! And id put the fan inline behind ur hood so that its pulling air thru ur hood not pushing thru it.. so, filter.. hood.. fan..outside. the flex ducting is handy inside ur box so u can have it attached and still move ur light when necessary. Since uve got a 10' run from ur box to the window id use the straight pipe from box to window..might look silly but if ur producing great product..who cares? Ur fan will also create heat inside ur box if that's where its located. So u might consider placing it outsode the box if possible.. id also keep reducers to a minimum if possible.. I'm on a phone so its a lil difficult to keep scrolling to answer all ?'s but pm me if u have more ?'s
