Thanks Dan! That is an absolutely beautiful setup! Looks like you modded out that cardboard box quite a bit!
So, if I'm seeing the pic correctly it looks like you're venting in regular outside air over the plants and have huge light levels in there with 2 led grow lights? How are you hanging the grow lights? Did you rest some wire mesh on the box and hang the lights from it?
I am growing on wire shelves but have used humidity domes to jack up the humidity for the flower stalk cuttings and even though there's some openings for airflow, it's not enough movement to prevent mold. I suppose I could try growing without the domes and see what happens. As long as I keep the trays filled with plenty of water I think that should keep them moist enough. Something to try for next year!
I agree on the azoxystrobin. It seems disappointing across the board but it could be that I'm just doing something wrong. Maybe my concentration is too low or I'm not applying it often enough. Don't know. I'll post another update later on today for the azoxystrobin vs. control experiment but spoiler alert: I'm still not seeing much difference between the two, even under a DLI of ~40.
Here's a couple pics of the propagation trays "in action", one with me pointing to the air holes.

I think your using open wire shelves - right? so adequate air circulation could probably be accomplished by a single strategically placed box fan or oscillating fan - whatever you might have around the house. All of my indoor growing is done in enclosed areas like 2X2 ft. and a 2X3 ft
grow tents but I just used cardboard boxes ha ha I'm cheap! so I found that small 40mm 12vdc fans worked well for me with variable 12vdc power supplies so the fan speed can be adjusted, probably wouldn't work well for open shelving though.
