I ordered several Hoya cutting from a trustful nursery in Thailand. The cuttings are all in good condition, but I wonder about the medium they were planted it. Obviously this is coco husk that was pressed together. The roots of the cutting are thoroughly entangled with this coco propagation disk.
My question is: How should I cultivate this cutting? My idea was to put sphagnum moos underneath each propagation disk and place them on a irrigation mat ( a mat that is able to soak up the underneath water).
