:bump: my question
Coarse perlite alone can be used to start some cuttings. This doesn't hold much water for long, but it is fine for rooting cuttings of plants which would ordinarily rot in higher moisture media. Coarse vermiculite alone has excellent water-holding capacity and aeration, but may dry out rapidly via evaporation if not covered in some way. A mix of 50% peat moss and 50% perlite favors good aeration. An equal mix of peat moss, vermiculite, and perlite is also good and favors moisture retention.
