Bends and angles in ductwork cause up to a 20% efficiency loss from your fan.
Carbon filters cause 15% efficiency loss on your fan.
Each air cooled 600w-1000w light needs an increase in fan power of 5%.
Tell me your room size.
Then tell me your fan size?
Filter size?
How many bends in ductwork etc?
If you give me the list of your setup and let's see first off if we can't get your room to a more manageable temp without buying anything.

You're pulling air from the room and exhausting it outside the room. So where does the replacement air come from? And what is its temperature?
Room size is currently 4x4. It will be 10x5 soon. I currently only have 1 - 60 CFM fan inside the duct for the fan. I was thinking of increasing it to 400 CFM?
I will have a max of 20' of duct, probably closer to 10'.
I don't have a carbon filter yet, going to need it. Last time was so stinky it could be smelt 20' outside the home.
Summer is approaching and temps hit 100 degrees outside, so venting from outside to cool the light I think is not an option?
I imagine, only 1 bend in my duct with a max of 2.
I have 25' of insulated 6" duct I just bought.
My 600w light, has a euro hood, I am actually pretty satisfied with it. I could feel the 60 CFM sucking air in, and blowing air out, yet I notice for at least 12inches underneath the glass it is unsafe. Part of my mistake I made last cycle was due to putting the light closer, I crisped the middle of my baby pretty bad and caused her to foxtail, so I cut my losses and cut 7 weeks in.
HotRod - It was winter for this cycle so I allowed the room in the air to be vented to the light, being that it was in a tent, the tent usually remained at 80+ degrees, and outside stayed about 70degrees if not lower.
With summer coming though temps will hit 100 degrees plus. =/
I vegged for 5 weeks, flowered 7 -cut.
I did not lolipop, I did not cut any of the lower buds really. I realize now I should have.
I had a worm problem in the roots the whole cycle, I do not have it this time - new room, new gear.
Sir Ganga - Will you explain the grow window a little more? I am not sure what you mean - don't let the plant grow tall possibly?
Gage - I am currently still in the tent, I can snap one of it if you'd like, but I believe you may be more interested in my room setup which will come together the next month or so.
Also I have a budget for the new lights, or what ever I decide to do of $400 but I can reach up to $600 if I feel its worth the investment.
I know I can just buy another light and etc and double output, but I am not sure thats the best scenario at this time. If you catch my drift... I upgraded security around here, but could use a lot more too.
