Yeah I have done like that. I just don't get more than about 60% to root.
I think it's because the clones can only be stuck about an inch into the cubes as they are so small.
Before when I cloned directly into coco or into big cubes I never had any problems.

Guess the best thing to do would be to buy a good cloning machine tbh.
I clone in trays now.
