well i finally got my setup complete with 5 6" vented 1000 watt lights and a 745 cfm 8" inline fan to draw air through them. i also have an ac which i used a splitter to exhaust both the hoods and the a/c however it seems like the a/c is not cooling after about 10 minutes. do they need to be exhasuted seperatley or is my plan to big? I cant seem to get the temp down past 90 degrees and it seems like the exhaust forces slow each other down when they meet at the splitter to exhaust.
