So here's the results after about 3- 4 weeks.
Both parts were planted at the same time and in the same grow area.
This one is pure mineral mix absolutely nothing else in it no earthworm castings, no fluvial stratum and they have not been fertilized.

This one is same mix except I did put a very thin layer of fluvial stratum on top, like very thin.

Neither pot were fertilized with anything after they we're replanted.
I do like the fluvial stratum because it's little individual balls rather than a fine peat like substance like an earthworm casting. But it grown moss like crazy
