We generally recognize that 80ºF and 60% humidity routinely produces good sheds, why this appears in 90% of care sheets. The math is easy 80ºF has a SVD (saturation vapour density) of 25.4 gm/m3 60% of 25.4 is 15.24gm . This is 60% RH.Originally Posted by Adamrhh
When you have a lower ambient air temp the SVD drops @ 78ºF you get 23.7gm/m3.
I like to use 15.5 gm/m3 as a target @ 78ºF this is 65% (rounded) You should have at least 65%, so 70% is just a bit too much (a little shy of one gram per meter square)
You should be trying to keep the humidity between 65-70% RH based on your ambients. So no actually you are spot on.
