I've had great success with my cloner this season. Most varieties rooted without issue as long as they were viable from the start (I had a few Black Jack's which did nothing, but the source threw them in for me and we both expected very little).
I'm winding down, but if anyone has cuttings they want me to drop into the cloner I'd be happy to give it a try. You'd ship me the cutting and I'd pot it up and you'd pay shipping back to you.
My 'fee' would be one rooted cutting so long as multiples rooted (if only one of a batch lives, it goes to the sender, not me). This assumes that it's a cutting I want <g>.
Thick green cuttings seem to work well as do dormant thick cuttings. Slender cuttings don't seem to have enough energy to take.
Please respond if there is any interest.
