Thank you! Yeah, it just became legal here medically, so i decided to get a decent set up. I have an inline fan with 442 CFM as well as carbon filter. I have a big fan in there now, but it keeps pounding my plants too hard even on the lowest setting, so i bought a bundle of 4 monkey clip on fans non oscillating. I want good airflow and possible a little temperature droppage too if they were turned up to a higher setting without hurting the plants. I have a 1000w MH light with the air duct cooling the light and exhausting out of the window. The light is dimmable, so i have had it on about 600 watts the first 2 weeks and just now turned it to 750 for the middle of week 2. The temp for 75 stays about 73-78 (depending on the time of day. I tried to put it to 1000w, but the temps were getting to about 85 (give or take), so for now im gonna leave it at 750 until i can figure out what to do about that. Im rambling now, but back tot he question, i really just want something that would be the best for air flow, to help get eferyhting flowing the best, Know what i mean? basically.... for having 4 flip fans, what is the best way to set them up
