Does anyone have any good links to ventilation guides or anything? I have a 36 cubic feet grow tent that i am having issues with keeping it smell proof. I have only one plant (LST) with around 14 colas. I have constructed a scrubber exhaust system but the smell is still escaping. I am in the process of duct taping around all the vent ports and such to try and get it to become as air tight as possible. My setup pulls air through the carbon filter (which is inside the tent) and then out through an exhaust port. My ports and vent tubing are 4" but the fan is a 6" 250cfm inline duct booster fan i bought for around 25$. My questions include, Is this fan sufficient for this space? or do i need to upgrade to the 120$ can fans? Does it matter if the air is being sucked through the filter on the inside of the tent or does it work better to push the air through the filter on the outside of the tent?
