Hello Marcus the way I do it is, get a small pot with coco in it, let it drain, cut your clone at a good angle, dip it in clonex, make a small hole in the coco with a toothpick or something similar, push clone into hole pushing coco round the stem of the clone to seal it in the pot, cover pot with a large zip bag and zip it up tight and leave it to do It's thing, you should have roots within 3 weeks or less.
The zip bag acts as a humidity dome and you don't need to water it, job done
.
Forgot to say, the coco I use has a light feed in it, enough to feed a good rooted clone for about a month or so, so don't need to use any extra feed.
