Sick Kefersteinia and Trichopilia

[neophyte]

i just did some research and i found out a couple things: the Kefersteinia aurorae naturally grows in cloud forests (rainforests but rainier!). they loooove humidity. keep temps cool to medium warm. lighting: low to medium. roots should never dry out.

i couldn't find an article on Trichopilia ramonensis, but i found one on its relative, Trichopilia suavis. turns out T. ramonensis is a natural hybrid between T. suavis and T. marginata (so the proper designation would be
Trichopilia x ramonensis). the suavis needs 85 to 90% humidity with strong air movement. watering should be slightly reduced during the winter but that's about it. trichopilia is sensitive to light - it grows in deep canyons. higher light seems to burn the leaves and doesn't improve flowering.

tl;dr: both plants need may be suffering from lack of humidity and/or too much light. bump up the humidity to 80-ish (or something high) and keep plants in filtered/dappled or low light.

if the sphagnum's old, replace it. but with such moisture-loving plants, i think sphagnum is optimal. unless you're an extreme over-waterer, i don't think you should switch to bark.
