Raven,
another way to look at this problem..
instead of fighting the symptom, fight the cause.
*something* in your growing methods is making a nice environment for this mold..
and its impossible to completely elimate mold anyway..it cant be done.
any moist environment will have *some* mold..
One thing that came to my mind when looking at your photos is "winter"..
it could just be a result of unusually dark and cool conditions..you probably wouldnt have this mold in the summer in bright sunlight.
I get surface mold on my CP pots in the winter, when conditions are pitch darkness and 35 degrees for three months..I get zero mold on the same pots during the growing season when the pots are in full sun between 50 and 90 degrees..so its all about the climate. (and the mold I do get during winter dormancy goes away by itself within days of bringing the pots out of the darkness!)
you can see some photos of the mold here:

about half way down the page..that mold goes away by itself after a few days of sunlight!
what is the overall conditions your pots are in?
light, temp, air circulation?
often just bright light alone prevents surface mold..
I think trying to beat the mold itself is the wrong way to go..you will never win that war.
you need to fight the cause of the mold..and thats usually easier anyway!

Raven,
I went looking for a description of your growing setup, and found this:
yeah..I think this is the main cause of your mold problems..
too dark, too cool and too humid.
many of your plants are REALLY far from the lights, and are in very dim light..
it might not seem like it to our eyes, because human eyes adjust to low light, but in reality plants more than a foot away from those bulbs are in
very low light..
and being close to those windows is probably also making it quite cool..
cool+damp+low light = mold.
IMO, you should remove plants from the bags, and you need to create different micro climates.
check out Jim Scott's ping racks from that same thread:

his plants are inches away from the lights, and no bags, and the bulbs also create some warmth.
his plants live in a summer day..your plants are in an overcast autumn afternoon!
Sorry Raven, but I think the mold is a direct result of your growing conditions..
its not optimal for the plants you have..especially in the winter.
