Here is my (freshly cleaned) CP/orchid case. I used to have many mini orchids in this case as well as a larger version in the same bay window. Having a you kid (now 3) running around has limited my time. This smaller case has slowly been used more for CPs, which don't need quite the attention.
I have a small 1 gallon ultrasonic humidifier below that pipes up to the top of the case. It runs a hand full of times a day with the small CPU fan. This keeps the humidity relatively high. The nep Ampullaria sure is growing like a weed. Might try a different type later on... one that stays smaller.
I recently acquired a few young sarracenias, so they will spend the winter inside this year with the cephs and heli.
