No, mycorrhizae live in a mutually beneficial relationship WITH the roots. The mycorrhizae live on the roots and the roots benefit from the mycorrhizae breaking down nutrients into a more easily useable form for the plant to use.
Mycorrhzae on their own will not encourage root growth on cuttings/clones.
Honet supposedly helps root formation, but I have never tried it. You just dip the end of the stems in the honey, then plant into the rooting mix/cube etc.
Cuttings will take root by just placing them in a glass of plain water, but it does take 3 weeks or so, just change the water every second or third day. Root development can be sped up with the addition of an air bubbler/air stone in the water.
Best to buy some clonex, it works well and works faster than anything else.
