I have two mini cymbidiums ('Sweetheart Sensation' and dayanum album 'Lady Elizabeth') that I rebloomed successfully. Here in Western Montana they grow outside on my east facing porch (morning sun) from late spring to fall, basically from last spring frost to first hard fall frost when daily highs stay consistently below 40 degrees. In the winter I grow them inside in front of a south facing window, up high where they are cooler and away from any of my heat sources. I grow them semi-hydroponically so they are never out of water, cyms do not like to dry out but they enjoy aeration. I've just switched all of my orchids over to MSU K-Lite fertilizer, so the hope is they'll only improve as I learned I was essentially starving my orchids previously... oops!.

Hope this helps!
