so there's mold every generation and can't seem to find the source. white mildew tend to coat the leaves every grow. humidity stays around 45-55F and temps are around 75-78F. Can the air circulation be a huge problem? have a 4ft oscillating fan covering a 8x4 area and carbon filter connected to duct vents running through 2 1k hps hoods going outside room. would a dehumidifier help? Possibly the more air flow throughout the area may help by adding another fan? and does wiping a neam oil? on the leaves to clean off the mold work?
