Hey riu I was wondering if it makes any sense to try my idea or would it be counter productive? Anyways I have a standard window AC of 6000 BTU, and a portable 14k BTU anyways that costs a hefty amount so I was wondering if I made a box behind the 6k and started my venting fans there could I then run through my lights and out room taking care of the heat I have 2 450 cfm fans and one 350cfm
