I used to clone in a clear plastic box I used to have.
Kept a heating pad on a timer, so it would come on max power 15 minutes per hour, keeping the temps high, and the humidity really high. I'd open the box twice or so a day to let in fresh air and to mist them with a mix of "R/O, pH balanced water, one or 2 drops of super thrive, and a SINGLE DROP of bleach (to retard bacteria growth in a humid environment)".
I would take the cutting, and put it in water to prevent air bubbles. Then take a 45 degree cut from the bottom of the stem, and even run the razor (sterilized) and scrape the outside of the bottom 3-4mm of the stem, then i'd dip the stem 6-7mm into the rooting hormone powder, then put them into a warm soaked peat pellet. Took me about 9-12 days before I would see new growth. I'm sure I have some pics around here somewhere, let me see if I can track them down.
