If it is your first time cloning and you are relying on the clone. I would go for trying the cloning gel. I have done both I got cuts to root in a week with Clonex, and almost 3 weeks without. I'm sure some people can get cuts to root fast than that without it. I also had better luck with the rapid rooters than the rockwool. you need to presoak the rockwool with the right ph because the material is basic in ph
