Late summer prune for Kiwi cuttings

Any advice on doing a late summer pruning of some of my Hardy and my Fuzzy Kiwi?  I want to try to grow some cuttings over the fall and think I should have 6 weeks before the first hard frost.  

I am building a misting bench for my shaded greenhouse and have some Vermiculite and Perlite for the media.  I am thinking of doing a mist spray of 5 seconds every 10 minutes for 24 hours a day.

The bench is self draining since it has hardware cloth and landscaping cloth under the media.  I can bring them into the house and put under grow lights before the first heavy frost.  

I will strip all the leaves except one at the top and cut it in half.  I will scrap the bark off around 1/2 inch at the base and apply rooting hormone before sticking the vines into the media. I will use little peat cups to hold the plants and for relocating inside.

Any suggestions? Is this the right approach?
 

My hardy kiwi rooted readily, just didn't survive dormancy, but it's very slow growing here.

I am planning on bringing them in over the winter and planting after it is warm.

Do you get cold enough for a good freeze? The soil can freeze the up to 2.5 ft deep here. You might not have the dormancy issues I have.

Our frost line is maybe 10 to 12 inches but it rarely gets a long duration cold.  Usually 3 to 4 nights below 15F at most.

Any update on your kiwi cuttings, Dennis? I am planning to do the same and wondered if the natural method of using cinnamon or honey works as an alternative to rooting hormone. I would think that these act as natural antibiotics rather than rooting hormones though. I don't have access to willow in my area.

I started with 9 cuttings and still have 7 going strong.  Some have new leaves and others have the original leaves.  I started them on September 4th and I will investigate them next weekend for evidence of roots.  I think they will be ready to go on to compost dirt mix soon. I will bring them inside over the winter to let them continue to grow.
I used a commercial rooting hormone I bought at a local seed store.  Never used cinnamon or honey.
SOme people can get away with just putting the cuttings in water for a month or two.  That might work for you if you have a lot of cuttings.  I might try that as an experiment since it is getting fall and the plants will soon go dormant.  I have some new shoots that look like some good possibilities.
