Getting a Ricordea to split...naturally

[scumchug]

IME, this recipe for forcing them to split.

Feed them every second day
High light (MH)
after a couple months put them into complete darkness for a couple days. This is the tricky part. Too long, and you will kill them. Not long enough, and they won't split. I found around the 24 hour mark works well. +/- a few hours depending on type.

If all goes well each one will split into 3 or 4 smaller ones.
