My biggest problem Elaine was not mites, but aphids. All over the freaking place. Did not bother me that much, but my wife seemed really bugged by the bugs. They just laffed at Neem oil and Insectacidal soap. Sevin was my last resort. **
I do think that maybe keeping it growing is not the way to go. Some folks strip them, wrap in bags and toss in garages. That would not work for me as it gets below 32 in mine and I ain't gonna heat it. Heh
** Part of my problem is that I have so many different types of things growing in my basement over winter. This past winter, I had maybe 50 different species from Brugs, Datura to Commiphora, Boswellia and banana. Among others.
Of course a few feet away, I was starting hundreds and hundreds of seeds. I have 8 banks of flourescents with natural light tubes and two 500 Watt warehouse lights - metal halide. Gets quite warm down there.
