I have had 0% success with rooting clones in rockwool and Ive tried to root 50.

I've used heating pads humidity domes and open them all the time and mist them and so on. They only seem to root after 2 weeks in a bubble cloner.

So what do I just grow them toabout 10 inches and snip the top 4 inches for clones?? and then let the plants grow on 4-6 main shoots?
