here is cloning a fan leaf,it can be done
Leaf-Bud Cutting
This type of cutting is made up of a leaf blade, petiole, and a short piece of the stem with an attached bud. Leaf bud cuttings are best of species that are able to create roots but not shoots from cut leaves. This method works best when you have a healthy plant, but have very little cloning material to work with because it maximizes the propagating material.

From my horticulture classes 20 years ago:

Any time you expose a section of the cambium layer, the living part of a stem or branch, you have a possibility of forming roots.

In one of our excercises we created roots on a ficus limb while it was still on a tree. We cut two rings through the bark of a branch about 2" apart. We then cut from ring to ring and peeled off the bark around that 2" length of branch exposing the cambium layer. We dusted that with rooting compound, wrapped damp spagnum moss around the exposed cambium, then covered that with plastic. I think we tied the plastic with twist ties or rubber bands. After a week or two of occasionally rewetting the spagnum, we removed it all and found roots growing off the limb where we removed the bark. It was a simple process of snipping the limb and planting in soil for our new plant.

I haven't tried this on cannabis. I imagine the operation would be a bit more delicate since the outer layer is much thinner, but would be interesting to see done on a large one.

b.t.w., this is why you cut clones at a 45 degree angle. It increases the amount of cambium layer exposed by almost 2X.

what u describe is called air layering and it can be done with cannabis
i know that pretty much anything will root,but alot hype was started that a fan leaf cant be cloned...
thats y i did this
it has to be cut with the bud still attached,not just cut and rooted

yes that is air layering we did the excact same thng at tec when i did my diploma

What you did was regular cloning, the clone from fan leaf has to be just that a fan leave nothing more nothing less, nothing like a piece of bud attached.
I have done it with just the fan leaf and the stem did root and stay alive for weeks but nothing else happened after that, it started to wilt after time though

ur missing the point....
instead of taking a cutting and making 1 clone,u can take a cutting and make several clones...i.e.cloning from 1 fan leaf

You aren't cloning from one fan leaf... you are cloning from one very tiny bud site (Before it grows) and making sure it has a big fan leaf connected to it to support it until it has leaves large enough of its own. It's the same thing as any other clone except rather than using decently sized bud sites, you are using the tiny underdeveloped ones with a big fan leaf for life support. You still need that bud site to get anything new to grow, you aren't simply rooting a fan leaf.
