Tarav makes some good points about using succulents with similar needs. Takes some guesswork out of the equation. I have used the styro peanuts and the big chunks of styro (waste management companies won't recycle them) for years in my big pots because still enables you to move the pot around. I just place the peanuts in those net bags that you get with those Cutie tangerines-in-bag so that when I want to reuse the peanuts, yet again, they are already contained.
Too many of my succlent frames have been emptied of semp and sphagnum moss by nesting birds...
