it never hurts to go with the bigger fan its nice to have the extra ventilation how are your plants going to be set up? like a stadium or something?
So after getting my first full on grow(outdoor) under my belt, I will now transfer my operations to an indoor set up and I have a few questions.
First my room discription :
I am building a 10ft X 8ft with 8ft ceilings. 2x4 framing, 1/2inch styrofoam insulation(white) all held in place with plywood. room lined with black/white 6ml plastic white side up.
Light will consist of 3x1k digi ballasts horti dual arc bulbs hangin vertical (no hoods)
A/C 15k btu window unit
growing hempy, 50/50 chow mix (hydroton / cana coco)
Venting with 6 0r 8 inch inlines(not sure what size yet, havent sat down and done the math, volume of air cleared every 5 minutes right?)
I will later add a forth 1k light, and dehuie/huie. hopefully that is enough info on my space to ask the following questions;
1) A/C unit, my walls will be 8ft high and i understand that heat rises, how high/low should i install my window unit?I was thinkin 4-6ft from the floor but im not sure if it should be above canopy to counter the heat or at canopy to stablize plants.
2) electrical, I will be tapping into an existing 240, 30 amp dual pull breaker that currently runs my pool, I was planning to switch out the breaker to a minidual 30amp with the added 2 additional 30 amps. lights will be run of a 4 light controller 240 in 30 amp fuse(hope i explained that right, electrician, i am not) I will be running my lights opposite my pool pump i.e. pool pump runs 10am to 4pm lights come on at 430pm. Will this be enough for the load i want to run (all above goodies included)?
I hope i didnt imberrass myself tryin to explain the electrical ish, and and all suggestions would be greatly appriciated. I will either update thread with pictures or start a new grow diary when the room is ready to rock in a couple weeks. thanks in advance guys!

Just as long as your light run time and pool run time don;t over lap you should be fine with that electrical setup.
A/C should do well at 3-4 ft off of floor. You can put higher if you want but IMO not needed.
Since you're going with the 1Ks, that's gonna be expensive in terms of power, the inline fans don't pull so much amperage, you might be able to save yourself some power operating costs if you pull more air through the space.
(I'm in PG&E territory, so I've gotten pretty anal about electric draws.)
You should talk to Cheech - he ran a VERY similar setup with plants surrounding 600s, if memory serves.
OMFG.
You're officially the first legal grower I've ever heard who actually takes electricity usage into consideration.
I've found that (IMHO) the CA answer to most issues is "throw more amps at it", which to me is laziness and not using creative solutions.
Hell, it seems like all the legal systems (RDWC) are in a race with each other to use as many watts as possible.
Sorry for the rant, but I was just amazed at a guy on another site who's claiming 1.5g/w, yet doesn't take into account the 3K watts in electrical he's running for his 1K HPS grow.
Fucking jaw dropping.
End rant now.
Quick question for you, couple actually, because you're describing my room almost to a T.
First, why do both that white rigid insulation and panda film? Why not use the white insulation on the interior of the room and have the white side facing in? Also, why not go for the 1" insulation? There's an added cost, but the benefit is being better able to control the room despite exterior conditions.
Second, why 2x4s? My husband built out my room using 2x2 (or was it 1x2s?) and since it's non-structural it's been just fine. Please note that I do not use an A/C, and so don't have anything quite like that mounted on or through my walls. I do have my Big 10" Inline mounted in that wall, though, and no additional structural supporting was necessary.
Third, go BIGGER with the ventilation. I'm using a 10" EcoPlus and it even sucked the fungus gnats out of the room. My room is all 8s, volume =512'cu. Fan is rated at 747cfm, so that means my room volume is turned over in less than a minute. You want turnover to happen at minimum every two minutes, size accordingly.
Since you're going with the 1Ks, that's gonna be expensive in terms of power, the inline fans don't pull so much amperage, you might be able to save yourself some power operating costs if you pull more air through the space.

If you're planning on running a sealed room, then you've moved outside the spectrum of my experience. I can only imagine you have to run it like an aquarium--entirely closed loop system.
You either need to bite the bullet now and buy the huey/dehuey and a CO2 unit to run in conjunction with your AC, or scrap the AC idea and do intake/exhaust (as Seamaiden does).
There are pros and cons to both methods (sealed vs. intake/exhaust) - there's a thread (sticky) you should read to get some info and make an educated decision about which route you wanna go.
Sealed is more expensive and complicated to setup and run, but it gives you total control over the plant's environment.
Intake/exhaust is much cheaper and easier to setup and run, but you lose some control.
You could always do a hybrid of the two, which is something that I'm contemplating/brainstorming about currently.
