In any event, put a fan on the plants.

An using outside cold dry air to fight it myself, looking for other ways.

Powdery mildew seems an endless problem for me. I am about to start a sulfur burning routine as a way to prevent the crap. Also, I spray the leaves with "alkaline water" (pH =8.4: 1/2 tsp. baking soda /1 liter of water) which kills the mildew on the plants. BTW, PM Wash is the same but effing expensive. Hope this helps.

Fight fire with fire, a product called Actinavate ( http://www.naturalindustries.com/ret...id=13&Itemid=3 ) will keep your plants from getting mildew and a bunch of other stuff and it can be sprayed on the leaves...........easy non toxic and safe and it's not expensive.

Being from Canada we battle with hot hot temps and very cold temps all the time, 58-70 seems very cool. Usually we run evening temps @ 70-78 and day temps @ 79-82 without as much as 10 degrees difference between night and day. IS there any way you can vent/exhaust from indoors? Ie. your rez area or another adjoining room to prevent the very cool temps from entering your room? Ive had to turn my exhaust from 7 mins every 40 mins to 2 mins every 40 in the winter with an extra heater in room to maintain temps. As for mildew, sulphur burners work but I find it tends to leave a sulphury tasting smoke. I use Nova in the first 3 weeks of flower just as a preventative, and then nothing gets sprayed after week 4. Spot spraying helps too, and then pick those affected leaves off after they've been treated. Mold likes cold and damp.

Make a box, room something that you can control air air in ,ventilation exhaust out,humidifier, air conditioner remember you control the environment in that room as you can tell its complicated but that's your solution good luck
