Monolena primuliflora (Monolena primuliflora)

All my Logee's plants are botanical garden quality! Unfortunately, despite my research and skill level as parent to 65 green gurrrls, my Monolena Primuliflora lost all its leaves. I placed in terrarium for a bit and it seemed okay but perhaps the leaves were resting on wet glass too long or perhaps sun was too strong or not strong enough and it showed stress and lost some leaves. Then I attempted a self watering technique that would also provide some humidity and that failed too. It was just hard to know the right moisture level to keep the plant healthy. When I thought moisture level was right it was probably still too dry then more leaves crisped up and turned brown. The self-watering technique I tried with a cotton-like wick was probably making the plant too wet. I have done my best to avoid plants requiring such high humidity since indoor climate in the mid-Atlantic region where I live reduces humidity to 22% and I can barely get above 40% on some days even with evaporative humidifiers running all day. I cannot risk mold growth with warm humidifiers. A rabbit's foot fern with some loss of stems in 3 inch pot (2 + yrs old), two ctnanthe burle marxii's in 3 inch pots (2+ yrs old), and one stromanthe triostar in 8 inch pot (2+ yrs old) , and 2 fiddle leaf figs in 10+ inch pots (2+ yrs old) are doing fine in my care but it was not enough skill to sustain this beautiful monolena plant.
