I really like the color on that Macho Mocha. I have not yet seen a bloom on mine but the pics of Macho Mocha blooming in the database are incredible. All of mine are in kind of restricted quarters so maybe I should put one in a bigger space and see if it blooms.
Stush, those pots are some kind of volcanic rock. They are common around here and very light and porous. More often they are used for bonsai, that's very popular in this area. There are a couple in the pics that are coconut shells too. I tend to use those a lot because they are free and always around. They rot out eventually but it usually takes a couple years.
