This last weekend I potted a few neofinetia in this coconut fiber purchased on Amazon.

I like the tidy look of the mounds when using fiber (at least when new), but I have reservations using it for more plants until I see how the first batch works out. Based on the much smaller weight gain after watering, it seems unlikely that coconut fiber will retain sufficient moisture.
The last three bails of sphagnum I purchased were unsuitable for use with neofinetia. I would up using them as regular garden mulch. I can find the very long fiber moss at about $50/package, but can't find AAA-equivalent anywhere. Until I see how the coconut works out, are there any suggestions on finding good quality bails of sphagnum.
