My Zygo is outdoors in the summer; indoors in winter. I also just repotted, resulting in a short sulking period. Zygos are not happy with any salt build up in the media (or so i was told), so i repot mine every 2 years. There is always some loss of leaves on older pblubs when I do. It is also important to wait until new growth is starting for the repot so that the plant re-established itself quickly. I repotted this Spring when 1 growth was evident and was a rewarded with a second growth. Since mine usually has 2 spikes per pblub, I'm looking forward to 4 spikes thus year
