growbox?good or not..

So,basicly i made these drawnings cos i got so much help from this forum about everithing,and now i anna help people who are stuck with theyr growbox..ok heres the drawning bout ventilation(get the air in)
so sise of my box is 4x4x7.2. and im using 40mm pvs pipes what i gonna run around the box so it will end up as a square using 90degree bends.(of coarse you have da drill loads of holes in so that air would get out) and then i connect these pipes behind a bathrom fan(have do be low rpm cos of the sise of the box)
reason why i just didnt use normal fan is cos of sise,that way the air would spread better and its not going to blow at the same place..
and to ectract the air out i just used 2 normal cheap pc fans...
ok now about lights...
like you can see on a drawning i used 1 250W CFL and 2 30W floro.that should be allright for that sise of a cabinet.and same way all the lights are running the same socket so,i sticked a we hand pully there between the cables,so that i can lower the lights when needed,or lift them higher..(only cost me 3 euro,its for a cheap close line)..i think that thats pretty much all//
SO experts,PLZ comment all my mistakes what i made<AND ALL THE ROOKIES,lissen experts,what they are sayng so yous all could have perfect growbox(mine is called POWERBOX) XD with perfect lovely budds...
and sry bout all my typing mistakes,english isnt my first langue:)

I don't know about this pipe air idea. Will it give same amount of air from every holes? You need some wind for the plants.

300w looks not enough for 16 sq foot. It makes approximately 1500lm per sq foot. You need to double it to get some good results.
Use T5 HO or PL-L and make it from four sides instead of 30w floros.
Or even use all T5HO or PL-L, don't use 250w single cfl. For T5 you can use 39W maximum and you need many. PL-L has advantage, higher wattage with short length. You can use 6x80w PL-L. This makes 2250lm per sq foot, this is enough. Use eight, 3000lm per sq foot, you're good.

PC fans are close to one side. Why is that?

T5 is a fluorescent available with high output option (T5 HO). But as I said, you need many of them to fit there because their waatges depends on their length as any other flourescents. You'd better look info for PL-L. Definitely better than T5, because they have higher wattage in short length.
Here is a simple calculation for you.
Say, in total you want to use 500W.
You can use 12x39W T5
or
You can use 6x80W PL-L

Price for them (approximately):
T5: 6 ballast=$75 , 12 bulb= $80-100
PL-L: 3 ballast=$35 , 6 bulb= $50-60

Hope this helps :)
