Cool - it just looks so different from all other Utric flower stalks that I have seen. It also initially looked like one bud with four sepals but I think that it may be two buds very close together. So, that's why I assumed it was another genus. I'll keep y'all posted on the flower if it opens - it's going to extend well out of my terrarium. I'm hopeful that it'll still bloom in the less controlled conditions of my living room.
I grow my U. sect. Orchidioides in a terrarium in my living room under two 25 watt LED lights. The lights follow the natural day/night cycle at around 10 degrees latitude (13/11 in the summer, vice versa in the winter). The temperature hits ~85 during the day and drops to ~65 at night. I was once trying to control the humidity but have since stopped as it's very difficult to do so in a terrarium this size without changing the temperature as well. But, it's enclosed so usually 50%-70% during the day and 70%-80% at night. I posted a full write up on the terrarium here
. I grow all of the others outside (climate zone 10). The outside ones get full sun for at least four hours per day.
