If you want to make it easy / make or buy an aero cloner or bubble cloner. You can make a bubble cloner for cheap as shit. It’s just a simple DWC set up basically. Container, air pump, air stone, net cups and collars.
It’s gonna take a bit more practice otherwise.
I cut, light scapes on side, I like technaflora gel.. gel it. Pop it in your medium - soak medium and cover.
The tricky part for me was learning how to work the stem/future root zone during the next two weeks. I’ve found you wanna have it very wet 2-3days then start cutting down the moisture in the medium.. couple days of so so moisture (let it dry out a bit). Around 6-7 days from cut i really make sure it’s just drying up considerably.
This is tougher to do in soil frankly. Rooting directly into coco worked well for me but the best is rockwool outside of an aero/bubble cloner.. you can just squeeze water out of it if there’s too much there.
Message me if you got more questions. I struggled figuring it out for a month or two but now I’m at 95%+ success.
