Powdery mildew is sensitive to heat. Neither species will grow at 90F (32C). and will quickly perish when above 100F (38C).
To get a complete kill maintain the temperature for an hour. You can minimize heat impact on plants in several ways. Heat the garden at the end of the day, as the lights are turned off. Since the plants are not photosynthesizing, they have lower water needs.
The heat treatment should kill off most of the fungus and its spores. The chances are there will still be some fungal re-growth. These can be eliminated using spot treatments.

Pruning

get a bag large enough to drop the leaves into and then cut them off into the bag. Remove the bag from the room. This prevents spores, from becoming airborne while being removed. Remember to wash your hands and clean the scissors or knife with soap and water, hydrogen peroxide, alcohol or bleach then apply your spray on the areas pruned.

Sprays
Cinnamon Oil and Tea
Garlic
Hydrogen Peroxide
Limonene
Milk
Messenger
Neem oil,
pH up (An alkaline solution with a pH of 8 will make the environment inhospitable for the fungus and will stop its growth. This is one of the simplest means of controlling the fungus. It can be used on critically infected plants.)
Potassium/Sodium Bicarbonate
Serenade and Sonata
Sulfur
Vinegar


Prevention


Filter incoming air to prevent spores from entering the room in the airstream.
Install a germicidal UVC light, like the ones used in food handling areas. The light is fatal to all airborne organisms passing through the appliance. This will kill powdery mildew spores that are airborne.
Spray the leaves with neem oil weekly. Neem oil presents both a physical barrier and a chemical deterrent.
Cinnamon oil and cinnamon tea can also be sprayed as a powdery mildew preventative.

Last resort
If none of these will work, put a bag over the plants that are infected and pull them
