Clone height

Can anyone suggest the best height to make clones for the swiftest propagation? I have been taking like 2-3" cuttings, but they are not rooting super fast. Talked to a guy that cuts from his mother at 8"...anyone have any experience or input. Thanks

I think you will get different answers from different people and also different strains act differently.... I have experimented with small clones to big ass chopping the top to make clones..... The big ones will clone but for me take longer, I found a 4 to 6 inch clone works best for me in the ez cloner... tale care.. Donut
