You’d prob have a heart attack walking into my grow. I run 70% RH in flower and like 80% in veg 
I think defoliation is much more useful for indoor than outdoor because height is not going to reduce the power of the sun like it will with an indoor light like hps or led. With indoor light if you move your light from 1 foot away to 2 feet away it will spread out 4x more but also be 1/4 of the strength it was at 1 foot. In order to have the same effect with the sun’s light you’d have to move 75 million km away since the distance is twice that.
I’ve also heard some interesting info on some podcasts I’d been listening to lately also. One of them was saying that the time you defoliate is important because if you do it too late (in flower) it could cause some issues. Because taking a bunch of leaves off reduces transpiration it also will reduce calcium mobility (calcium moves through the plant with the transpiration stream) making it potentially more susceptible to rot. This combined with flushing (I don’t flush a lot of people still do though) which will lower Ca even further can make it even more of an issue.
Something else I found interesting was that since you are massively reducing transpiration after a massive defoliation, your plant will in turn uptake less water so changing your irrigation based on that temporarily (feed less for awhile) would be helpful to avoid humidity spikes from the media staying wet longer than usual.
On some podcast (I think Josh Neulinger) was saying how he’s been to so many facilities that were having major issues with PM being everywhere were running RH levels of 45-50. Mentioned that in Ag industry PM is known as a dry mold and needs lower humidity for the spores to be able to desiccate and spread elsewhere. When the RH was raised to 70 it went away and never came back.
I’ve also seen some leaves in my grow room with water droplets on them which isn’t a good thing. I’ve slowly but surely been trying to wrap my brain around the differences/ relationships between relative humidity, absolute humidity, dew point etc. Air at a higher temp can hold much more humidity than lower temps so a RH of 60 at lets say 100f will hold more water vapor than 80% at 55f. I’ve noticed in my grow room that I have major temp swings from lights on to lights off (like 85f to 69-70f) I suspect that this might be at least in part responsible for rot issues I’ve had. I’m gonna work on keeping my room warmer during lights off so I don’t get any kind of condensation. I feel like this grow I’ve already noticed a reduced severity so hopefully a step in the right direction.
