Substrate for peace lily in riparium

This is like a double post. I copy myself from a journal thread where I describe planting a Spathiphyllum peace lily in a riparium planter. I have a few useful observations. Spathiphyllum are easy to acquire, cheap and extremely hardy. All of the ones that I have tried have grown well in riparium conditions, although some do grow rather big. There are a number of small/dwarf selections available.

To plant this one I began by trimming the roots back to about 1 1/2" in length. Then I positioned the plant in the planter with the top of the crown about even with the top of the planter cup. I filled around the roots with round clay pellets acquired from a local hydroponics shop, tapping the planter as I poured so that the pellets would settle in around the roots and fill voids.

I only filled to about 3/8" from the top rim of the planter cup so that I could top the pellets with a layer of a finer-grained clay gravel. This step is important. The gravel weights down the pellets, which would otherwise tend to float away if the water level were to rise over the top of the planter cup. I think that they look better as a cap than the round pellets and they might also retain some nutrients for the plant roots.

Spathiphyllum apparently have rather modest nutrient demands and they seem to do well with the fertilizers dissolved in the aquarium water. I have also planted a few Anubias, including A. congensis, in this manner, as they also require a more open rooting environment.
