Do you think the Ac blowing directly on the flowering plants would be a problem? Do you think I will have a problem maintaing proper temps in the veg room, A wall of some sort, between the two rooms, Would a 70 cfm exhaust fan between the flower and veg room do the job, then that raises another problem with the exhaust from the veg room being dirty, or should i put the filter>6in inline fan in veg room>duct from inline fan to>lights in flower room 2 600 hps>exhaust outside. So it should make a big circle, fresh air from Ac in flowerroom , then 70 cfm fan,between flower room to veg on the floor, inside veg room would be the filter inline fan ducting to lights then out side. I hope this makes sense. I don't think the 70 cfm fan would be enough though thinking about it now.

Thanks in advance
