Understood...but you also have your Gram scriptum listed as needing a rest...and it's not supposed to...hence my concern.
Dendrochilum uncatum is from an area that does get a reduction in rainfall during winter but they also get a lot of heavy condensation and it should be grown without a rest. I also don't know of any Cattleya hybrid that needs one.
I'm just trying to help you...please don't take offense
