New to the catts

[justintimedc]

Hello! I just started adding a few compact growing catts to my collection a few months ago. I think I have around 10 of them now. Most seem to be doing OK, but I have lost one, and I think I am losing another one. Most that I have purchased were potted in sphagnum moss, with clear pots. I water all my orchids once a week, in the shower, soak them good, then back on bakers racks with nice south facing windows. Since these guys were generally smaller pots than my phals, I figured they would need AT LEAST once a week watering, but I am wondering if being too wet is my problem with these couple of plants. The moss never did totally dry out, should I let it get pretty dry? The plants that are not doing so well had some rotten roots, then the leaves turned a yucky brown/black/yellow and got soft, fell off. Do catts need to be dryer than I am used to? Or is something else going on?
