Yeah... What Dutch said. If the source of intake air is humid then doubling the exhaust wont really help. You need a de-humidifier, they are a lil pricey, around $100, but will help significintly.
killfrenzi Reviewed by killfrenzi on . Humidity!!!! Hey All, Well with the onset of summer temps my RH levels are coming up to as much as 67%,sometimes more! My room is approx 24sqft,8x8x2.5ft?.Lit with a 600hps,12''oscillating fan with 8''rvk exhaust and scrubber.I also have an 8'' rvk for intake-but its not switched on as temps dont go over 85. So,the qustion is,what would work better at getting the humidity down-Switching the intake on or,joining both rvk's inline with 4'' duct,then the scrubber on the end of it all.Will this 'double' my Rating: 5
