Cloning that shows roots fast?

Hello,
I have a dwc cloner running, one cutting sitting in plain water (ph'ed to 6.0), and another sitting in a cup with a dome over the top. Its been a week, and all 3 clones show no roots after 8 days using 3 different methods. I prefer just the plain water method as it doesnt require anything, however this is the slowest method im sure.

Anyway to get roots within 5-7 days?

I use jiffy pellets and soak them for 24 hours in plant magic from vitalink, I use clonex on my cuttings and then into a unheated propagator under a 45w led panel (cheap chinese) this time round I saw roots after 6 days.

Some times it just takes time

I wait 7-14 days no more

after scraping the cut, I dip in clonex and stuff it into the rapid rooter for hairy roots in a week
