Hi! I think I might be decent at this indoor gardening, and I started reading the sticky, the noobs guide. I also have been reading a couple of books.

My plan is to convert an existing bedroom closet with limited depth. It is actually a very wide double closet, but I am going to use half of it (for now). The half I will use is about 78x28x95 (width, depth, height) inches, so the volume is about 120 cubic feet. I will vent to the attic, and attach a filter, using Rhizome's noob guide, 80 CFM seems generous, and the lowest fan I have to pick from is 160 CFM. Oh, and the space rates a "B", according to Rhizome's guide, which is good enough for me. The only bad thing is the depth as you face it is small, like I said 28".

Questions:

1) I read a book that said the CFM for the fan should be 3 times the cu. ft. of the room so it exhausts the volume 3 times a minute!! What? mistake?
2) What is the affect on airflow for a 90 degree turn in a duct? I was thinking for the ceiling vent I would need this to run the fan and filter across the ceiling.
3) If I use a rectangular horizontal reflector, then I should put the long sides parallel with the short sizes of the room (28") correct? This limits which reflector I get, and the ones with built in duct ports wouldn't work. Therefore I was thinking of the Hydrofarm Radiant Reflector.
4) Wattage... I am torn between 250W and 400W. At first I will grow what I can old school organic, nutes, and soil in pots, but eventually I want to learn ScrOG. 250 W should do 2x2 feet max I'm told, but with 400W I can maybe get a wider area in that room, but is it overkill, or is the space too small for it? I like the power savings with 200W, but I hate for my plants to not get what they need.
5) One book said a minimum of TWO oscillating fans is required, really?
6) Venting straight into an insulated attic okay?
7) If my exhaust fan is on a timer or environmental control unit, what is the affect on plants during the time when it is off, in other words, don't they need lots of fresh air (CO2) all the time? It seems bad to ever not run the exhaust fan.
8) The intake will be to the adjoining closet (through false wall), is this bad? the closet isn't air tight or anything...
9) I live in a coastal area, the temps are moderate, I plan to make my night from NOON-6pm, sound good?
10) Equipment, can you say if the Active Air 4" inline fan (165 CFM) is quiet and long lasting, or should I get the 4" Vortex? What do you think of Phresh or Phat filters vs. Charcoal Filter Elf (coconut)? What do you think of the Hydrofarm Radiant reflector vs the Sun System 2? Bulbs? Agrosun Gold Halide, Sunmaster Warm Delux? Ballast, Sun System Cropmaster switchable 400W, or maybe Lumatek 250W/400W switchable/dimmable electronic?

Thanks!!!
