Great job!

During the fall-winter time usually it takes months to grow some poor roots on Sansevieria. And some types do this much slower than other in my expirience.

Actually right now I have one Kirkii leaf in water for 4 months, and still nothing.

Its better to do it yourself. Coco coir, Coco chips, perlite. 3:1:1

That’s it.
