basically i have a 5 foot wide by 7 foot tall by 9 foot long room. hanging from the ceiling i have the can 66 filter with my 6 inch 440 cfm ho fan pulling air out of the room at the opposite end of the room out the top of the room just below that hole is a smaller fan pulling air back into the room. on the 600 watt hps i have a 100 cfm fan pushing air through the light and through duct work to a hole that leads to the outside of the room. when i leave the room and shut the room and stand infront of the vent duct that the carbon filter and fan is hooked to and have someone blow smoke through it i can smell it outside the room. I have a switch that turns the fan on the filter up or down i have it set at 70% which is around 360 to 370 cfm and my filter at max is rated at 412 cfm. I just can't get the smell to fade that much its strong with the smoke i am wondering if my plant smell will be an issue?
