So you're talking about air layering, and then fogging roots (in what ill assume to be a working fogger cloner), and you think you'll get done in 3 weeks? I quoted that video you said you were looking for, it says 3 weeks to even get roots in the bag of soil when air layering. It's not going to happen that fast, and it's already proven there are much faster options. Cut a clone normally and try to fog it i say, if that isn't faster itself adding other slower ways,.. ugh,.. i don't know, i don't get why. Air layering is a neat thing to do, I'm going to try on a house plant, only.
