How long will it take for roots to show for clones

Need advice please fellow members thank you alot ty

Depends on how your cloning them?

Can you use rock wools for cloning?

Get one inch rock wool cubes. Seedling tray (thick walled one if possible or they break easily). Humidity dome.
Soak rock wool in ph adjusted water or theyll be way off on the ph and wont work as well. After soaking remove and place in cloning tray. Do not squeeze out, just shake out once.
Cut lower branches that are though and at least 4.5 inches long. Dip in clonex gel (not powdered rooting hormone) cause clonex works great. Then stab into rockwool and mark names on a plant marker.
Place dome over the clones and make sure that its warm and theres a floro tube or two above them thats on for 24 hrs straight.
Every morning and night spray the leaves and the inside of the dome lightly. Make sure the rock wool never dries out. If the cubes dry out the roots start to die. But if its too wet in there they all die too. So just damp all around. 9-14 days and youll see roots, then break them to the life outside of the dome SLOWLY! And transplant.

Do you need a dome?

I never use a dome. But, it probably depends on where you are and the RH. I think they root faster without a dome but with a heating pad.
