They grow like weeds in the Philippines, and humidity there is through the roof too with frequent rain. But they are provided some shade from the heat of the sun so often times under the trees. Same here, if I try to put them out it will be zapped by our dry heat during summer and with no rain here it is just so frustrating. So better to have it growing indoors near some nice light, it still needs some light for its photosynthesis. But one thing for sure, it loves water, especially on very warm days. Eventually as seasons change, adjust watering, just a bit more interval when it starts to get cooler and sun is less.
In addition to keeping the media moist, like all other plants, container has to have good drainage and I would add some perlite in the media just to keep it light and open, so it will not go too compacted. That should help the roots get air while being moist.
Moose, as with any repotting to be done, expect the plant to be in adjustment mode, it will undergo some shock, but once it gets acclimated again, it should return nicely. Looking again at the photos, so the last two photos shows very good promise of recovery. Good luck on your plants!
