I've had only one experience with this combination, so the results are not very meaningful, anyway this is my experience:
I deflasked three macodes petola. I potted two of them in 50% hydroton - 50% sphagnum peat and the third in hydroton in s/h. I put them in my mini GH where, as I said, there is an average of 80% rh, and 3 pc fan always working. My little GH is: 3ft x 1.66ft x 6.66ft (H). Consider that this mini green house isn't perfectly sealed. The results so far (less than two weeks): the two macodes in 50%-50% are growing quite well, the other in s/h rotted after few days!!
But I'm not able to see if the mistake is mine or s/h isn't the best choice for this specific case.
Ray you said that in your GH you have an average relative humidity like mine. So my question about s/h is: Is there a meaningful difference in growing with or without high RH?
