125 plants in 137SF!

OK im new here , me and my friend are doing 125 plants in 8"pots with 4x1000w hps in 137SF space with 8 feet high room ,what bothers me is that im not sure if i should use reflectors with 6" entries to suck heat and smell out or regular batwings and 2 can fans.We light up december 1st and here it gets -20 in the winter oustide and i dont want to have the need of a AC or to have to change reflectors .its not ceiling or basement its regular floor ,please keep in mind we are just aiming at quantity here......what do you guyz think?? i will post later pictures of the process your help will be much apreciated

lol...I feel you on the cold bit. spent a mo. last year below zero, here. I'd look @ pulling from outdoors w/ your intake if heat becomes an issue.

Go with air cooled hoods, you can keep the lights a little closer to the plants allowing for even better penetration
Here is a link to the best reflector on the market: http://www.bghydro.com/BGH/itemdesc.asp?ic=HLRESMXXXL06&eq=&Tp=

Here are a top and bottom pic of it:





It has such an awesome spread cause of how huge it is

great! i will look into that i def need bigger reflectors and yes the dryer entry is next to the room and the wall has a 6" entry already i can see outside in it, but is the magnum xxxl much better then the yield master II ? for double the price? and one question a bit off topic, where can i find information about how much exact water per ppm measurements in both cycles im trying to do things a bit more cleaner this time and last time with soil.....

One other thing is my CAN FAN 6" 440 CFM and CAN FILTER is enough for the 4 lamps and all those plants? i think but might be borderline and i dont want to spend if i can save ..a little on a budget here hehe...

Eather way any air flowing threw is better then none...

but the best would be to do an indivisual 6" to each 1000, 2 8" fans with 2 1000w on each or all the 1000s on a 12" inline fan.

oh didnt see that you already had a 6 in hole..

in that case I would recommend a 8 in fan with a 8-6" reducer on the side going out and a 8" y joint with 2 8"-6"y spliters.. so you got 4 exaust lines goin out ur one whole, you could also just snake line all ur lights together, you dont really have to worry much in that much coldness..
