great rooting medium
This stuff has been great for rooting some of my more resistant cuttings. I have a woody umbrella plant that is always giving me trouble but this media has worked well so far to root cuttings. Everything else I drop in her roots perfectly, every time so far

Exo stratum
What I like about this product, stratum is a volcanic rock that is an excellent product when growing rare plant stems that is much better than placing rare plant stem in just soil or water reducing rot. I highly recommend this product to increase new plants from mother plant.
