Mites are being handled with HotShotz strips which are the only non-spray product I have found to work. Leave 'em up, take 'em down, let the dying mites lay more eggs, hang it back up for a week. Remove for another 3-4 days. Repeat until all mites are dead.

You're right about temps. . . Need to be kinda warm. My friend has an identical cloner in a room that is like 90 degrees and 90 percent humidity. Clones root in 5 days.
