Shannon - no that's not a silly suggestion. I had 3 mature zygos all fall victim to spot/streak and rot when brought in. 2 recovered indoors - I learnt to water sparingly about every 3 weeks on these. I know it doesn't sound right but the new growths need time to root. Perhaps these 2 I will keep indoors ( they are in 1 pot ) but they do love it outdoors in Summer. Currently I count 7 new growths of about 4 inches each.
I also have a cattleya that almost rotted last year indoors. However this year its fine - 5 new growths, and the secret - watering roughly every 3 weeks too, with almost zero fertiliser.
I think zygos get a double whammy - the 'natural' streaking which then makes them more susceptible to black rot when cultural conditions change ( moving from outdoors to indoors ). The seedlings that you read about - these were outdoors and transitioned to indoors with no problems at all. Of course everyone's cultural conditions are different so you may have had another experience.
