Inline fan question

I am running a 170 cfm inline blower in each of my two rooms. Attached to each of these is a decent carbon filter. I currently do not have air cooled lighting.

My question is, if I were to get some air cooled lighting, is it definitly a separate blower fan, or is there some configuration where one blower can service the lights as well as carbon? Would you just attach the carbon to the blower with the duct from the lights attached to that?

Rooms are in the basement, or it would be a lot hotter. It's been pretty hot here lately (for Maine, anyway) but I have managed to keep the rooms in the low 90s. Would air cooled reflectors help that much?

Air cooled reflectors will be a huge bonus to your plants. U will notice a nice change in growth and flowering. Big Ups. Yeah just put filter on one inline and the second inline attached to both lights and air coming in from out of grow area, across lights and out of grow area.

CARBON FILTER>>>"Y" adapter>>>AIR COOLED HOOD (x2)>>>"Y" adapter>>>INLINE FAN (450 CFM Vortex)>>>>>AIR SILENCER>>>>EXAUST.

thats how we roll.

I have a room that is divided in two by a plywood wall. I run one fan, one filter and 2 air cooled lights.

I have the intake in the Big room. My filter sits on the floor of this room and is connected to the light with duct. From the light I run duct through a hole in the wall to my exhaust fan in the Small room. On the exhaust fan I have a Y. One end is connected to the duct from the Big room, the other connected to the light in the Small room. I have a passive vent between the 2 rooms.

Thanks guys. Each room is 10x12x6, so 720 cf if my math is correct. So approximately every 4-1/2 min the room is exchanged (theoretically). Is that adequate?
