Tolumnia in S/H success

[Nanotyrannus]

I've had this Tolumnia in a clear disposable cup with plain LECA for 2 years now. It's from a seedling population. The reservoir is only an inch high. I've never had any rotting issues at all. I actually think I could've gotten a bloom sooner, because I've been extremely lazy with this plant. It's gone weeks without water, much to its detriment. I've also recently learned that the Tolumnia is a heavy feeder! Its newest leaves are quite large after I've adjusted its feeding regiment.
