Hi Cat, they will resume more active growing in Spring when weather warms up better. During winter, I try to be careful in watering, ambient temps are easy to get cold. So I would dunk them in water for an hour and really shake them dry, so no water is pooling in the crown/center, and continue on to air dry.
During warmer days, I can dunk water them overnight. They can take it, and again, shake them dry, tip them over, and allow to air dry. They really like good humidity levels.
Rain water is really good, I just use tap water since we don't get rain here often. Typically adjust watering as seasons change.. lesser during the cold months, more during summer. You can also mist them often, if you have them outdoors during summer months. They like part shade, but if you really want to see good blooming, the will need good bright light, not too much direct sun, it may fry them, especially during the summer months. They are not too heavy feeders, so I just spritz them orchid fertilizer..if I remember
But remember they are monocarpic so once they bloom, it is the start of its downhill life span, but it will/may grow pups, cradled in the lower leaves, then mommy plant dries out in the next year or so, and babies will be almost half the size of mommy plant by then.
