I would say that I can grow spagnum fairly well. I have even done so in drier pots where I keep my heliamphora. It even grows in full perlite. Ime the key to growing spagnum properly is high high humidity. Once that basic need is supplied, most species do very well. Red spagnum seems to do incredibly well in low water. The super chunky tight grain spagnum that you commonly see on highland species in my experience likes a lot of water and very low temperatures. And the looser green sphagnum that grows like palm trees tends to use even less water and favors lots of light. I would say it depends lots on the species, so as you acquire plants through trading and purchasing, see what variety works for you. Then, you can use excess sphagnum from all of those pots on the other plants you own.
