OK, here is the deal. I basically built an 8'x8'x90" room inside of a spare room. It is very airtight, will be well vented using Vortex fans, sound-proofed, insulated, own wiring and panel box, blah blah blah.

Now, I have two 1000watt HPS lights. Super Sun 2 with the sealed hood. Of course I am going to use two 6 inch fans, one to blow air in the first light, the other to suck out the second light and then blow out of the room. (its my understanding those fans both suck and blow) They will have their hood vents connected via insulated duct in the middle.

Now, my question is this, how high would you folks suggest I cut my holes on my side walls for my fresh air in, and hot air out? Or is that something we could debate for the next 2 years and nobody would ever agree?

My concren is keeping the supply/exhaust lines as level as possible while maintaining the ability to raise/lower lights based on the characteristics of what strain I am growing. Less resistance with no bends, etc etc etc......You know where I am comming from. I want excellent ventilation so I can keep lights closer and get every lumen possible.

Or..............could I put a 90 degree elbow on each fan and just cut them near the top of the room. Up against it here folks, any input would be appreciated. (no that would not work on intake side..........damn)

I have seperate room to veg in using MH, and they would be going in this room at 14-18" for 12/12 til done.

I guess ultimately what I am trying to be able to do is have the best setup possible no matter if growing an Indica or Sativa.
